A.3 Diagnostics messages [ID:151040988811]
Diagnostics alarms
A diagnostics message is generated for each diagnostics event and the DIAG LED on the
DI16×24VDC PA 󹪞ashes red or the MT LED lights up yellow.
The diagnostics messages can be read in the diagnostics bu󹪜er of the CPU, for example.
Diagnostic messages are assigned either channel-speci󹪝c to an input or assigned as module
messages to all inputs. All channels are switched o󹪜 for diagnostics messages that a󹪜ect
the entire module. Only the corresponding digital input is a󹪜ected by diagnostics messages,
which refer to individual channels.

Assignment Meaning Remedy
Wire break 6
H
Channel Impedance of encoder circuitry is too high Use another type of encoder or
wiring, for example, use con‐
ductors with a larger cross-sec‐
tion

Module Error is reported because the events occur
faster than they can be processed in the
system.
