Hi this is my first post and I hope I would get information from very Elite people on this forum.
I want to communicate a Master controller to other slave controllers ( here controllers are dedicated PLCs designed for controlling the machines). But the Master and slave controllers work on their own propritory protocols ( all the slaves work on same protocol as they are of same make).
The Hardware iterface is ready with me having two ports and they are sufficient for interfacing.
I have the example software developed for interfacing between ( converting)Propritory protocol and Modbus Protocol. In that software, the blocks used are: Modbus_Open, Modbus_Close etc..
On the similar lines I have to prepare the blocks for Opening and closing the ports for propritory protocols.
If I could know how it is done for Modbus, I would be able to implement it for the propritory protocol.
So whether somebody can tell me what is meant by Opening and closing the port and how it is achieved ( for example in Modbus protool)
Thanking You
