Force Control Gateway is used in surveillance systems
In the Xingcheng Special Steel energy management and control system, due to the differences in on-site collection sites. The gateway uses OPC Client, OPC Tunnller, Modbus and other communication protocols to collect on-site data. Each site uses Modbus as the forwarding protocol to forward the data to the IO server of the energy management and control center. To ensure centralized management, dispatch and balance of energy supply and demand.Industrial gateway
Channel configuration
Use the OPC Client communication protocol. In the gateway configuration software – channel setting, select “OPC Client” for the channel protocol, enter the “server node” and “server name”, and set the server user name and password in the “extended parameters”. .
To use the OPC Tunnller communication protocol, you must first install the “OPC Tunnller” software in the on-site host computer (OPC server), perform “Communication Configuration” and “OPC Configuration” in the software; select the channel protocol “OPC Tunnller Master” in the gateway channel configuration “, and enter the IP address of the OPC Server, and write “2500” as the port number to ensure communication between the gateway and the OPC server.
Use Modbus communication protocol. In “Collection” – “Channel Configuration” “Basic Parameters”, select “Modbus Master” for the channel protocol and enter the P address of the PC Server, and write “5008” for the port number.
The collected data is forwarded using the Modbus protocol. In “Forwarding”, “Channel Configuration”, “Basic Parameters”, select Modbus TCP Slave for the channel protocol. Enter the IP address and port number of the forwarding port under the communication port TCP Server and write “502” “.
To use the OPC Tunnller communication protocol, you must first install the “OPC Tunnller” software in the on-site host computer (OPC server), perform “Communication Configuration” and “OPC Configuration” in the software; select the channel protocol “OPC Tunnller Master” in the gateway channel configuration “, and enter the IP address of the oPC server, and write “2500” as the port number to ensure communication between the gateway and the OPC Server.
2.2 Device configuration
Create a new device under the channel and add measuring points in the device: (l) Fill in “Roll Name”, “Description”, “Type” and “Read and Write Attributes” in “Basic Parameters”; (2) In “I/ Enter the variable address in OPCServer in “Connection Item”.
When you want to perform operations on the data collected on site, click Data Conversion to perform four arithmetic operations on the collected data. The collected data can be viewed through the data monitoring tool.
2.3 View forwarding points
Send some status. In this way, add the corresponding signal point to the forwarding configuration in the SCADA interface, establish channels and devices respectively, and send the address to the collection point to connect the data to the EMS system.Add it to the forwarding configuration and view the forwarding through the ModScan tool.
3 Force Control Gateway is used in monitoring systems
The channel and equipment configuration are the same as the monitoring point settings. In the collection point configuration, the read and write attributes select “Read/Write”; in the Xingcheng Special Steel EMS system, the water purification plant is used as a whole-plant production in the forwarding measurement point configuration. The forwarding type selects “DO discrete water delivery provider. There are 6 riverside water pumps that need to be remotely controlled. Due to the net output”, in the SCADA system, the forwarding address is “00001” instead of the SCADA data of the water plant collected by the gateway. , you can force the gateway to enter “10001” (take offset 1 as an example).
Take remote control.
4 Conclusion
(1) Use the force control gateway to remotely control the riverside water pump of the water purification plant. Safe and reliable. The signal points collected in the gateway include both read-only points (monitoring) and read/write points (monitoring), achieving the role of physical isolation.
(2) In the steel energy management system. The force control gateway can be used to remotely monitor real-time data and achieve remote control. It provides reference data for energy prediction and balance, and serves as a good reference for other energy management systems.
