Introduction Libraries are used to store reusable blocks. The blocks can be copied into a library from existing projects or they can be created directly in the library independent of projects.

Standard A Standard Library is installed when you install STEP 7. You can access this Library standard library from the SIMATIC Manager (File 4 Open 4 Libraries) or from

the Block Editor ( Overviews 4 Libraries). The library contains the following S7 programs :

Communication Blocks:

Functions (FC) for communication between the CPU and the distributed I/O via communication processors.

Organization Blocks: Organization Blocks (OBs).

S5-S7 Converting Blocks:

Blocks that emulate STEP 5 standard function blocks and that are necessary for converting STEP 5 programs.

TI-S7 Converting Blocks:

Generally usable standard functions such as analog value scaling.

IEC Function Blocks:

Blocks for IEC functions (IEC: International Electrotechnical Commission), such as for processing time and date information, for string processing and for selecting maximum and minimum.

PID Control Blocks: Function blocks (FBs) for PID closed-loop controls.

System Function Blocks:

System Functions (SFCs) and System Function Blocks (SFBs).

Miscellaneous Blocks:

FCs and FBs for switching between daylight savings time and standard time (summer and winter times).

Note Additional libraries are added when optional software is installed.

Obtaining Help There are various ways of obtaining help:

1. You use the Help Contents menu to activate the general help.

2. You use the Fl hot-key or the icon in the toolbar to start the context-sensitive help.

Tabs

"Hot words"

• "Contents": Displays a list of help topics under general headings.

• "Index": Allows you to access the help information by displaying a list of available terms in alphabetical order.

• "Search": Enables you to look for certain words or expressions in the help topics.

Certain words are highlighted in green and are underlined with a broken line in the help texts (called "Hot words"). A mouse click on these "Hot words" leads to a further help text with detailed information.

Context-Sensitive Help ...

... Activating

With the context-sensitive help, you can find information directly connected to the selected object. As the slide shows, the object can be a system function or it can be an STL instruction in a block, for example.

You can activate the context-sensitive help from any tool by selecting the relevant object and then pressing the Fl function key.

Use the "Help on STEP 7" button to jump from the context-sensitive help to the general help.

Note You can find additional information on STEP 7 in the electronic manuals.

Choose the following menu options to open the electronic manuals:

General You use the "Set PG/PC Interface" tool to define the connection between an application such as STEP 7 and a module such as CP 5611. The tool is activated with Start - Settings 9 Control Panel .

Access Point Other examples of access points are:

• CP_H1_1 for SIMATIC NET (Ethernet)

• CP_L2_1 for SIMATIC NET (PROFIBUS)

• DPSONLINE for ProTool/Pro DP-Slave

• Micro/Win for the S7-200 software

• MPI (WinCC) for the WinCC Software

Interface Parameter Here, enter the module used, such as, CP5611 and the interface used, such Assignment Used as, MPI. If you connect the PG to the PROFIBUS, use the setting CP5611

(PROFIBUS). To save a switch-over of the PG/PC interface, you can also use the setting CP5611 (Auto). The bus parameters are then automatically

determined. With this setting, however, the connection takes longer.

Properties In this tab, you adapt the parameters of the interface. For "Address", enter the MPI address of the PG. This must be unique in the network.

To make communication possible, the "Transmission Rate" and "Highest Node Address" parameters must be the same for all nodes (stations).

The "PG/PC is the only master on the bus" setting is only activated if only slaves are connected to the PG.

Diagnostics With this, you can check whether a connection can be made.
