I have a problem with combox-e.
without 1756-CNBR,it's OK that plc connect with combox-E.
plc:
1756-L61*2;
1756-ENBT*2;
1756-CNBR*2
1757-SRM*2;
in RSlogix 5000
I have only used Atlas torque runners with Profibus. It is most likely an address error (length, config) or a card setting error. Try to reconfigure to a new address after you check settings (some had dip switches).
