Ge’s BENTLY 3500 system is a unique monitoring system that reduces operating costs, improves product quality, increases plant safety, and maximizes plant availability. The 3500 system can send a variety of data to other systems, and through the support of these data, the quality of the operation judgment is higher. Its function is to monitor the operating state of the unit shaft system online, send the unit’s interlock protection signal to the interlock shutdown system, and communicate with the PLC system.
2. Bentley 3500 system hardware and software configuration
2.1 Hardware Configuration
The hardware part includes: 1 DELL GX270 microcomputer as an operation station and engineer station function. A 3500 rack and card parts
2.2 Software Configuration
Microsoft WINDOWS 2000 as the system operating platform; System 1 as the operating software, version 5.00; RackConfiguration Software as engineer configuration software, version 3.60; Configure user programs. They are installed on the operation station (engineer station).
First, PLC system
1. The RTU manager module (RTM700B) and other card status indicators in the PLC system are running, and it is found that the OK light in the RTU is steady on (normal state), the TX light is off (normal state is blinking), and the other card indicators are normal.
2, check the RS485 communication cable, after inspection: the signal cable and the joint are tightly welded, and the multimeter test is in good condition.
3. Check the working status of the COM subroutine in the PLC program, and find that the COM program is in a standby state (that is, it is not in a normal working state), activated by the software, and there is no data transmission. Other programs are running normally.
4, PLC control station cold, after the communication program is not automatically activated.
5, replace the RTU manager module (RTM700B) module of the slave station and the master station in the PLC control station, repeat the operation of 3 and 4 steps, and the data transmission between the systems is not restored.
To sum up, the communication problems caused by PLC system and communication cable fault are basically eliminated.
2. 3500 system
1. Check the operating status of the MODBUS gateway module (3500/92) and other card status indicators in the system 3500, and find that the OK indicator of 3500/92 is blinking (normally steady), the TX/RX indicator is off (normally blinking), and other status indicators are normal.
2, the card after hot plug, restart, still does not work normally.
