Module Diagnostics
Introduction
This chapter describes error codes and fault conditions to help you
troubleshoot the 1756-HSC module.
1756-HSC Error Codes
Errors are displayed on the Connection tab of the Module Properties dialog
box in RSLogix 5000 software and in the .EXERR field of the message
variable when you reconfigure the module.
The final number of each code represents the channel number that is reporting
the error: 1 = channel 0 and 2 = channel 1.
For example, code 16#0011 means that a BADCOUNT has occurred on
channel 0.
The following table lists possible errors on your 1756-HSC module.
