Disabling group diagnostics
The "Group diagnostics" parameter is used to enable and disable the transfer of channel-
specific diagnostic messages (for example, wire break, short-circuit) of the module to the
CPU. For reasons of availability, you should disable group diagnostics at
unused input or
output channels of the F-SMs listed below:
●
SM 326; DI 8 x NAMUR
●
SM 326; DO 10 x DC 24V/2A
●
SM 336; AI 6 x 13 Bit
WARNING
Group diagnostics must be enabled at
all connected channels of fail-safe input and output
modules which operate in safety mode.
Verify that group diagnostics is only disabled at unused input and output channels.
Diagnostic interrupts can be enabled optionally.
The following applies for SM 326; DI 24 x DC 24V, SM 326; DO 8 x DC 24V/2A PM, SM 326;
F-DO 10 x DC 24V/2A PP and SM 336; F-AI 6 x 0/4 ... 20 mA HART:
By disabling a channel in
HW Config you also disable its group diagnostics function.
