Goals and Symptoms
'140NOA6xxxx Interbus-S' modules are not recognized in the traffic cop.
Facts and Changes
Causes and Fixes
The '140 NOA6xxxxx Interbus-S' modules are displayed in the traffic cop with a black question mark
inside a yellow circle when 'ProWORX 32' is connected to the PLC. (The module functions correctly).
The reason for this is because the status information is not provided by the executive firmware of the
'140 NOA6xxxxx Interbus-S' module. Since there is no status information for the 'ProWORX 32' traffic
cop to use, it doesn't know the module type and displays a question mark.
