Hello All,
I have an application using a SLC 5/05 processor with a SST profibus card. The application controls 10 servo drives and field bus devices that will be communicating over profibus. I'm looking into using only 1 SST card (32 input words & 32 output words) for controlling all 10 drives and field I/O. The drives will use approximately 120 total words.
My questions relates to the use of the M0 and M1 for drive information. Has anyone had any problems related to receiving/sending drive information and plc scan time? It's my understanding that receiving M0 and M1 data takes more time than I,O. I'm concerned about certain drive parameters not being immediately set or reset because of the longer communication times required for M0 and M1. Are there any issues I should to be aware of when using M0 and M1?
Thanks
