Connecting PLCs?
Connecting PLCs?
(OP)
How do we connect AB SLC5/04 PLCs using a data highway cable so that they communicate with each other.
Teh actual problem we have is we have a motor controlled with a plc. Now we have another plc in another location. How do we connect these two plcs using a data high way cables and control the motor with the second PLC in another room. we also have a rsview software available that should be used

Having said that, I still wonder about your application and why you need to do what you are saying. Wouldn't it be easy to control the motor directly from the same PLC it is connected to? Plus you have rsview. You can do wonderful things with that to control both PLCs.

So using DH+ how do we configure the PLCs?
RE: Connecting PLCs?
Now in your logic setup an MSR block in you PLC that has the motor connected to it. Set the MSG block as a read. I suggest putting it here because you then can monitor the MSG block for error and take appropriate action with the motor. Such as in cases where the remote PLC is not available you could stop the motor.
I would suggest reading more registers than required incase more control is required later.
With out knowing your setup better that is all I can say.
This should be rather simple.
What PLC do you have? PLC-5, PLC-2, SLC50/4 ect.
What programming software do you have? Logics, A.I. Icom ect.

1. how to make the PLCs talk to each other and
2. How to program RS View( Cause we donno anything about programming RSView.)
