Hello,
I have a project that I have never attempted before coming due.
I need to trend varibles in a Ultra 100. (can not use the analog out, already being used)
So I would like to set up a RS485 4 wire network, (15 drives) , master polling device will be a Controllogix 1756-L55M12. I will be using a RS232 to RS485 adapter on the com of the processor.
The Host commands are ASCII.
HAs anyone done this before or have any insight ?
Any help would be appreciated.
Thanks
Chuck
