Status Indicators for the 1756-OF8I Module
All 8-channel modules have Status (ST) and Fault (FLT) indicators on the
front of the module that have no equivalent on the 6-channel modules. All
8-channel ST and FLT indicators operate according to the description in the
8-channel module manual, even when in Emulation mode. Also in Emulation
mode, only ST, and FLT indicators 0...5 are active, indicators 6...7 are always
off.
The following table describes the status indicators.
