Hi everybody,
In my company project, We have 4 PLC and computer, connect follow diagram:
PC
|
|
Master PLC (CP1H)
|
-------------------------
| | |
| | |
Slave 1 Slave 2 Slave 3
And some case:
- Master PLC communicate with PC to display status information of machine (Alarms, running, stop,...) and master PLC will collect these info from 3 Slave PLC.
- When user run/stop any icon on screen of computer, computer send a command to Master PLC. Next, master PLC check a command and send it to right Slave PLC (1 or 2 or 3).
This is my an idea but i don't know
1. Am i an idea true ?
2. which is protocol network used ?
Thanks for any help.
