What kind of programming is simpler and easier to use for communication between general DCS and other PLCs? Can an expert explain the program or write it down? Thank you, do you usually just use the CPU properties and change the frequency, or use a communication module to connect to the PLC? If you don’t know how to write, can you please tell me. ///
Generally, the communication between DCS and PLC directly uses the 485 interface, just use the MODBUS protocol, and just configure the master station and slave station. Generally, no special programming is required.
Generally, DCS has a communication module, which may require programming for data processing, or use analog signals (such as: 4-20mA) programming control, or status input programming control, the question is too general
What you said above makes sense. Generally, communication does not require reprogramming, as long as the addresses and nodes are defined for each other!
Generally, the RS485 modbus-RTU protocol is used to assign the address and set it up. No special programming is required.
Generally, if you write it yourself, either modbus or opc will work: lol I usually use these two.
Profibus and Modbus communication protocols are more commonly used. Just assign the address. If you communicate with third-party software, you can use OPC.
