Application-specific fault processing (in-rack modules) by program
Presentation
Algorithm
Application-specific fault processing can be performed using the debugging and diagnostics screens.
It may however be advantageous to use a program to perform this processing.
The following algorithm is an application example of the detection and management application-specific (in rack) module faults by a program.
Test the %S10 bit
(general input/output default)
No default of input/output
No
%S10=0 ?
Yes
Locate the module at default in the rack
%Iy.MOD.ERR = 1
Diagnose the default module
READ_STS %CHy.MOD
%MWy.MOD.2
Locate the channel at default via
%Iy.i.ERR = 1
Diagnose the default channel
READ_STS %CHy.i
%MWy.i.2
