How we can communicate PLC to PLC

Question

Accepted Answer

PLCs can communicate with each other through various methods such as Ethernet, serial communication, or fieldbus protocols.

PLCs can communicate using Ethernet/IP protocol, which allows for real-time data exchange between multiple PLCs.
Serial communication, such as RS-232 or RS-485, can be used to establish a direct connection between PLCs.
Fieldbus protocols like Profibus or Modbus enable communication between PLCs over a shared network.
PLCs can exchange data using OPC (OLE for Process Control) servers, which provide a standardized interface for communication.
Examples of PLC-to-PLC communication include synchronizing data between multiple production lines or sharing sensor information between different machines.

Accepted Answer

We can communicate PLC to PLC through various protocalls one of them majorly used is ethernet, through IP address.
