GE DS200FCGDH1B On site interface module
The GE DS200FCGDH1B gate allocation and status card is a high-performance and highly reliable control card developed by General Electric. This card board is specifically designed for precise control and management of various door operations in the system, including its allocation and status monitoring.
Firstly, the DS200FCGDH1B card is mainly used to receive SCR trigger signals from digital signal processing cards. After decoding these signals, the card can accurately allocate door operations, ensuring that each door can be opened and closed according to predetermined parameters and timing.
Secondly, the DS200FCGDH1B card also has powerful status monitoring functions. It can not only obtain real-time status information of the door, but also return this information to the control system through the VME motherboard. This allows operators to constantly understand the current status of the door and make corresponding control decisions.
Communication protocol refers to the specification and agreement for exchanging data between communication devices. In GEPLC communication, there are several commonly used communication protocols:
1. Profibus is a commonly used fieldbus communication protocol developed by Siemens in Germany.
Profibus supports point-to-point and multi-point transmission, suitable for control and monitoring tasks. It has the characteristics of high speed, reliability, and good real-time performance, and is widely used in the field of industrial automation.
2. Modbus Modbus is a commonly used serial communication protocol suitable for communication with PLCs. It is simple, open, and easy to use, with good compatibility, and can support point-to-point and point-to-point communication methods.
Modbus supports multiple physical layer media, such as RS-485, RS-232, TCP/IP, etc.
3. Ethernet Ethernet is an Internet based communication protocol that can support high-speed data transmission and network connection.
In GE PLC communication, commonly used Ethernet protocols include Ethernet/IP and Modbus TCP. Ethernet/IP is an industrial Ethernet communication protocol with high performance, real-time performance, and reliability.
Modbus TCP is an implementation of the Modbus protocol on the Ethernet, which can provide faster data transmission speed and larger network coverage.
