I'm planning for TPM to connect several SLC 5/05 on ethernet and use a PLC to collect information ( counter an timer value or I/O status, other ) from each PLC. What will be the correct way to read and collect the information from the PLCs to collect the data, and write in the others. thank you

Hi:

I give up, what is TPM?

Thanks,

Bill

a TPM is Total Preventive Maintnance

There are many many ways to do what you are trying to accomplish. I am not sure that there is a "Correct" way. A method would certainly depend on how you want your final data formatted.

Do you just want to read data from, say five PLC's, into one common PLC, or do you want to transfer data to excel, or some other type of paper report.

To read data from the other PLC's into one I would just use a MSG instruction
