I am having trouble communicating with a 1747-ASB Module (series: A). I keep getting a PRC (partial rack communication) error on the 1747-ASB display screen. I am able to read inputs from the remote rack but cannot write outputs to the remote rack. I am trying to use a 1736-A13 (series: A) rack as a Remote I/O rack for a Control Logix controller (Logix 5555). I am using a 1756-DHRIO Card as my scanner and the 1747-ASB as my adaptor. It is a straight run for the cable, these are only the 2 cards on the circuit. Both have 150ohm end of line resistors. I have the Dip switches set up on the 1747-ASB as
SW1 - OFF ON ON ON ON ON ON ON
SW2 - ON OFF OFF ON ON OFF ON ON
SW3 - OFF ON OFF ON ON OFF ON ON
The remote rack is logical rack #40(octal)/#32(decimal).
Any help would be appreciated, and if you have any questions, please ask.
Thanks, Kyle.
