requirements 3. Intrinsic Safety
Intrinsic safety system is to be composed in accordance with the requirements of the classification society.
The Zener Barriers are applied to the 4-20mA Input/Output signals and the RTD Input signals from hazardous areas and contact barriers are applied to the contact input signals.
4. Power Supply
- AC440V, 60Hz, 3 Phase or AC380V, 50Hz, 3Phase
- Voltage : ±10% nominal
- Frequency : ±5% nominal
Fully covered all of IAS power, except engineer’s cabin human interface station(Extension VDU), is assured by uninterrupted power supplies. A UPS is fed from normal feeding line, the other fed from emergency feeding line. The autonomy of each is 30min. Both of normal and emergency feeding power are always coming from ships power bus. On the wheelhouse station(DOSS), ECR stations(DOSS), CCR station(DOSS), DOHS, DOGS, and PCNS are used normal line in case of both feeding alive. When the normal feeding fails, those are change to emergency feeding by automatically. This change has a specific lag time then supported by small UPS to compensate the interruption during change over.

Figure 3.2.1 Graphic Display
Graphic displays can be built so that the operator can monitor and manipulate the process directly from them. Both continuous and discontinuous processes can be managed from graphic displays. Basically, any data point parameter or sequence can be monitored and manipulated from any graphic display.
Graphic behaviors such as blinking, color changes, bar graphs, appearance of subpictures, and numeric values can be controlled by parameters of data points

3.5 DOPC ІІ (DEO Process Controller ІІ)
1. General
DOPC ІІ is a multi-function controller employing control loops, logic functions, sequence control and I/O processing.
- Built-in control / calculation algorithms
- Sequence control implemented by CL (Control Language) - Distributed I/O for space saving
- Remote I/O capability by fiber optic connection
- Peer to peer communication with other DOPC ІІs over the DEO-NET using the tag name basis
- Memory back-up by flash ROM
DOPC ІІ consists of ;
- DOCM (DOPC Control Module)
This is a main module of the DOPC ІІ consisting of the control modules and the communication interface modules.
- Distributed I/O
The I/O modules are mounted on DIN rail.
2. DOCM (DOPC Control Module)
DOCM Configuration shows the DOCM system. The DOCM is composed of the following modules.
- Control Module (MSC) - Ethernet Module (ETM)
- X-BUS Module (XBM)
Three (3) sets of control modules (MSC) have redundant configuration, and execute the same processing synchronized with each other. The ethernet module (ETM) and the X-BUS module (XBM) compare outputs of three (3) MSCs, and get data by “logic of majority”, i.e., 2 out of 3. Even though one of MSC outputs incorrect data, the remaining two (2) data are correct and used for the control and monitoring.
