Allen-Bradley Df1 Protocol - Plc Error Code Tables - C-more micro EA1-S6ML Hardware User Manual

Allen-Bradley DF1 Protocol – PLC Error Code Tables
The following PLC error tables cover possible errors that are detected by the panel from Allen-
Bradley PLCs using the DF1 protocol. This includes full and half duplex communications for
the MicroLogix 1000, 1100. 1200 & 1500, SLC 5/03, /04, /05, ControlLogix, CompactLogix
and FlexLogix, and full duplex communications for the PLC5.
Note: The following errors can be generated from the designated PLC, are monitored by the C-more Micro-
Graphic panel, and displayed on the panel's screen as a hexadecimal value in panel error code P499, if active.
Please refer to the PLC users manual for additional information.
