The Automation module... command inserts a function block diagram.
There are three function block diagram versions available: admin_normal, admin_mid and admin_big, which can be selected from an icon menu.
The normal function block diagram is quite sufficient for normal connections, but if you de-sign very large control loops, you can select a big function block diagram, which is four times as big as the normal function block diagram. Mid function block diagram is about two times as big as the normal function block diagram (Figure 65 Available function block diagram sizes).
If you want a big or medium− sized function block diagram, the easiest way to create it is as follows:
After starting the CAD tool, use the Page−Create command and give zero (0) as the number of pages. At this point the tool asks the size of the desired function block diagram.
ADMIN_NORMAL
ADMIN_BIG
ADMIN_MID
Figure 65 Available function block diagram sizes
The following data can be entered for the administration part of the function block diagram using a dialog:
LOOP TAG TAG_CODE
LOOP NAME (FIELD 1) LOOP NAME (FIELD 2)
LOOP STATUS complete
NAME OF PLANNER −
DATE OF PLANNING YY−MM−DD HH:MM
NAME OF MODIFIER −
DATE OF MODIFICATION YY−MM−DD HH:MM
PROCESS AREA 1 PROCESS AREA 2 PROCESS AREA 3 PROCESS AREA 4
The data that you write on the fields will be stored in the administration part of the function block diagram. All data except the loop status will be visible in the function block diagram.
7.14.2 Function module...
The Function module... command inserts a continuous control or its extension part in the function block diagram. Generally, one function block diagram contains one continuous con-trol and its possible extension parts. An exception to this rule is the usage of PLU−I/O functi-on, in which case a function block diagram includes not only the normal continuous control but also the actual PLU−I/O function and possible extension parts of both configuration func-tions.
Four versions of both continuous controls and their extension parts are available: fad-min_normal, fadmin_mid, fadmin_big and fadmin_long are the continuous control alterna-tives and extension_normal, extension_mid, extension_big and extension_long the corre-sponding extensions. The alternatives differ in size.
The normal or mid continuous control frame is quite sufficient for normal connections. The long continuous control frame is used mainly for recipe configuration. The big continuous control frame is used for designing very large function block diagrams.
A long continuous control frame is double the height of a normal frame and big is double the width of a long frame (Figure 66 Available continuous control frame sizes). Mid continuous control frame is about two times as big as the normal frame.
FADMIN_BIG
Figure 66 Available continuous control frame sizes
The following data can be entered for the administration part of the continuous control using a dialog:
FUNCTION MODULE NAME pr:TAG_CODE.F
PACKAGE IDENTIFIER AP01
EXECUTION INTERVAL<ms> 1000
EXECUTION ORDER 20
The data that you write on the fields will be stored in the administration part of the continuous control. All data except the continuous control execution order will be visible in the adminis-tration part.
When adding the extension, the dialog only asks for the identifier of the continuous control.
7.14.3 Externals in continuous... − External continuous inputs
The External in continuous option shows you an icon menu from which you can select an external input data point for a desired signal type (ana, anaev, bin, binev, intl, intlev, ints, intsev, bo, fails, float, other configurable type or table) for continuous communication. When you have selected the desired symbol, the symbol’s insertion point is also its connection dot i.e. the point from which the connection line will be drawn, for instance, to the input of a function block. (See further information of table type from chapter 10 Configuration of Tables.)
When you have inserted the symbol, you will be asked about the name, comment text, initial value of the input and the transfer interval. The name and comment text will be displayed in the symbol, but the initial value and transfer interval will not be visible. If the field is left empty or there is the default value of the field, the transfer interval is the same as the execu-tion interval of the continuous control. However, if a limit value HKEY_LOCAL_MACHINE\SOFTWARE\Metso Automation\EA\<Engineering environ-ment version>\Environenviron-ment\TRANSLIMIT is defined in the Windows registry and it is de-fined to be bigger than execution interval of the continuous control, the value of TRANSLI-MIT is used as the transfer interval.
A continuous external input data point is marked with the following symbol:
Figure 67 External continuous input
7.14.4 Externals out continuous... − External continuous outputs
The Externals out continuous... gives you an icon menu from which you can select an exter-nal output data point for a desired sigexter-nal type (ana, anaev, bin, binev, intl, intlev, ints, intsev, bo, fails, float, other configurable type or table) for continuous communication. (See further information of table type from chapter 10 Configuration of Tables.)
When you have inserted the symbol, you will be asked about the name, comment text, initial value of the output and transfer interval. The name and comment text will be displayed in the symbol, but the initial value and transfer interval will not be visible. If the field is left empty or there is the default value of the field, the transfer interval is the same as the execution inter-val of the continuous control. However, if a limit inter-value HKEY_LOCAL_MACHINE\SOFTWARE\Metso Automation\EA\<Engineering environ-ment version>\Environenviron-ment\TRANSLIMIT is defined in the Windows registry and it is de-fined to be bigger than execution interval of the continuous control, the value of TRANSLI-MIT is used as the transfer interval.
A continuous external output data point is marked with the following symbol:
Figure 68 External continuous output
7.14.5 Externals out conditional... − External conditional outputs
The Externals out conditional... gives you an icon menu from which you can select an exter-nal output data point for a desired sigexter-nal type (ana, anaev, bin, binev, intl, intlev, ints, intsev, bo, fails, float, time or table) for conditional communication. A conditional output can only be used together with the ccoX and ccoX2 function blocks. (See further information of table type from chapter 10 Configuration of Tables.)
When you have inserted the symbol, you will be asked about the name, comment text and initial value of the output. The name and comment text will be displayed in the symbol, but the initial value will not be visible.
A conditional external output data point is marked with the following symbol:
Figure 69 External conditional output
7.14.6 External ports in... − External input ports
The External ports in... option gives you an icon menu from which you can select an external input port for a desired signal type (ana, anaev, bin, binev, intl, intlev, ints, intsev, bo, fails, float, other configurable type or table). This port is a combination of an external continuous input and an input interface port. (See further information of table type from chapter 10 Con-figuration of Tables.)
After you have inserted the symbol, you will be asked for the name, comment text and initial value of the interface port and as well as the name, comment text and transfer interval of the external continuous input. All data except the transfer interval will be displayed in the sym-bol.
The external input port functions as a separate external input and an input interface port which are connected to each other. The name field of the external continuous input can be left empty i.e. the external data point will not be formed and the external port functions as a regu-lar interface port.
An external input port is marked with the following symbol:
Figure 70 External input port
7.14.7 External ports out... − External output ports
The External ports out... option gives you an icon menu from which you can select an external output port for a desired signal type (ana, anaev, bin, binev, intl, intlev, ints, intsev, bo, fails, float, other configurable type or table). This port is a combination of an external continuous output and an ouput interface port. (See further information of table type from chapter 10 Configuration of Tables.)
After you have inserted the symbol, you will be asked for the name, comment text and initial value of the interface port and as well as the name, comment text and transfer interval of the external continuous output. All data except the transfer interval will be displayed in the sym-bol.
The external output port functions as a separate external output and an output interface port which are connected to each other. The name field of the external continuous output can be left empty i.e. the external data point will not be formed and the external port functions as a regular interface port.
An external output port is marked with the following symbol:
Figure 71 External output port
7.14.8 Direct access left... − Direct access ports, connections on the left
Direct access left... gives you an icon menu from which you can select a direct access port for a desired signal type (ana, anaev, bin, binev, intl, intlev, ints, intsev, bo, fails, other configur-able type or tconfigur-able). Left indicates that the connection dot is at the left side of the symbol. (See further information of table type from chapter 10 Configuration of Tables.)
When you have inserted the symbol, you will be asked about the name, comment text and initial value of the direct access port. The name and comment text will be displayed in the symbol, but the initial value will not be visible.
A direct access port with connection on the left is marked with the following symbol:
Figure 72 Direct access port, connection on the left
7.14.9 Direct access right... − Direct access ports, connections on the right
Direct access right... corresponds to direct access left..., only the connections are on the left side of the symbol.
A direct access port with connections on the right is marked with the following symbol:
Figure 73 Direct access port, connection on the right
7.14.10 Interface in... − Input interface ports
Interface in... gives you an icon menu from which you can select input interface ports for desired signal types (ana, anaev, bin, binev, intl, intlev, ints, intsev, bo, fails, modstat, other configurable type or table). (See further information of table type from chapter 10 Configura-tion of Tables.)
When you have inserted the symbol, you will be asked about the name, comment text and initial value of the interface port. All data will be visible in the symbol. One function block diagram cannot contain several interface ports of the same name, therefore it is necessary to use reference points if the data of the port are needed in several places.
An Input side interface port is marked with the following symbol:
Figure 74 Input interface port
Interface ports also contain definitions of the data structures for the administration of the se-quence and subsese-quence:
seqadmin, type seqmng, sequence administration data structure
subadmin, type lseqmng, subsequence administration data structure
MODSTAT−interface port
Each function block diagram must contain one interface port of type ktstat. This port controls the execution of the function blocks of the PCS continuous control and continuous control’s data communications to other continuous controls of the same control task. It is possible to add an interface port of ktstat type in the function block diagram with the desired initial val-ues using the MODSTAT interface port. In case a port has not been added in the function block diagram, the port will be added automatically.
The update class of the continuous control at the duplicated Process Control Server
It is possible to specify an update class for the continuous control at the duplicated Process Control Server using the MODSTAT interface port. There are three update classes: A, B and C. Using the update class, the user defines how often the continuous control data is updated between the main and reserve machine.
7.14.11 Interface out... − Output interface ports
Interface out... corresponds to interface in... except that it is located at the output side.
An output interface port is marked with the following symbol:
Figure 75 Output interface port
7.14.12 Locals left... − Local data points, connections on the left
Locals left... gives you an icon menu from which you can select a local data point for a desired signal type (ana, anaev, bin, binev, intl, intlev, ints, intsev, bo, fails, float, other configurable type or table) with connections on the left. (See further information of table type from chapter 10 Configuration of Tables.)
CONNECTING A LOCAL DATA POINT
A local data point is marked with a round symbol with connection on its left or right side. The connection lines connect the data point to other objects to be connected. You draw the con-nection line directly from the local data point to the input or output of a function block or to another line. For the line−to−line connection you need a connection dot, which you select from the Draw menu (DOT). Then you point the exact location where the connection lines meet and place the connection dot here.
When you have inserted the symbol, you will be asked for the name, dimension, initial value and comment text of the local data point. The name and initial value will be displayed in the symbol.
The icon menu also contains the Any−type data point. Its type is user−definable and it accepts a long initial value extending to several lines (e.g. in connection with the ’tfunc’ function block). When the function block diagram is checked, these lines will be combined into one initial line.
A local data point with connections on the left is marked with the following symbol:
Figure 76 Local data point, connection on the left
7.14.13 Locals right... − Local data points, connections on the right
Locals right... corresponds to locals left..., only the connection is on the left side of the sym-bol.
A local data point with connections on the right is marked with the following symbol:
Figure 77 Local data point, connection on the right
7.14.14 Constants left... − Constants, connection on the left
Constants left... gives you an icon menu from which you can select a constant for a desired signal type (ana, anaev, bin, binev, intl, intlev, ints, intsev, bo, fails, float or other configur-able type). Connection to the function block is on the left.
When you have inserted the symbol, you will be asked for the initial value of the local data point. This value will also be displayed in the symbol.
A constant with connections on the left is marked with the following symbol (example: ana−
type signal):
Figure 78 Constant, connection on the left
7.14.15 Constants right... − Constants, connection on the right
Constants right... corresponds to constants left... but with connection to function block on the right side of the symbol.
A constant with connections on the right is marked with the following symbol (example: ana−
type signal):
Figure 79 Constant, connection on the right
THINGS TO BE NOTED IN CONNECTING DATA POINTS:
You cannot make a connection between two data points: in other words connections local−local, external−external or local−external data point are not possible.
Constants used for initializing data points (or function blocks) are not enclosed in paren-theses.
7.15 Fblocks1 − FUNCTION BLOCKS
From the Fblocks1 pull−down menu you can pick different kinds of function blocks and their variations.
Figure 80 The structure of the Fblocks1 pull−down menu
am... Analog measurement function block
am2... Analog measurement function block 2
ahs... Analog history function block
ahs2... Analog history function block 2
bhs... Binary history function block
bhs2... Binary history function block 2
bm2... Binary measurement function block
cnt... Counter function block
grp... Group control function block
mca... Motor actuator control function block
mgv... Magnetic valve control function block
mgv2... Magnetic valve control function block 2
mgve... Time−stamped magnetic valve control function block
mtr... Motor control function block
mtr2... Motor control function block 2
mtr2e... Time−stamped motor control function block 1
mtre... Time−stamped motor control function block
pid... Controller function block
qcnt... Quantity function block
vlv... Valve positioner function block
When you select a function block type from Fblocks1, Fblocks2 and Fblocks3 pull−down menus, you will get an icon menu containing the available versions of the function block.
Different versions have different numbers of inputs and outputs to be connected.
To pick the desired function block type you pick the icon presenting it. By contrast, if you select the function block from the FbCAD screen menu item Fblocks, you will not get an icon menu but a text menu containing descriptive names for the function blocks.
The following figure presents the variations of am function blocks as they are shown in the icon menu and the respective descriptive variation names as shown in the am submenu of the screen menu item Fblocks1.
Figure 81 am function block variations
The following things should be noted when entering function blocks:
When you pick a function block from a Fblocks menu, you must specify the block’s execution order in relation to other function blocks in the loop. On the basis of the specified execution order a number corresponding to the order is automatically generated before the function block’s name.
For example, if you pick an am function block and set its execution order to 2, the generated function block name will be 2am.
Constant values for function block parameters and initial values need not be inserted in pa-rentheses.
The configuration constants of previously entered function blocks can be changed through the Values item in the Edit menu.
When you have inserted a function block, you will be asked for its data in a dialog. The data to be specified in the field depend on the function block. They include the execution order of the function block, the name of the direct access port, and those function block parameters that are not connected in the function block diagram.
7.16 Fblocks2 − FUNCTION BLOCKS
Fblocks2−pull−down menu is similar in operation to the Fblocks1 pull-down menu. It only contains different function blocks.
