Suggested action: Description:
Fault
type:
ChB Comm Loss
36022
Soft,
warning,
or none
The PLC Communications
Adapter Board has detected a
loss of channel B
communications with the PLC
controller.
Check for a break in the
communications cable. Verify that all
connections are intact. Clear the fault
by issuing a Clear Fault or a Drive
Reset command, or by recycling
power.
Check parameters 430 (ChB RIO Flt
Sel) and 431 (ChB RIO Warn Sel) to
determine the drive response to faults.
These parameters determine the
resolution of the condition, either fault,
warning, or none. Both parameters are
bit coded.
• Bit 0 determines the resolution to
ChB Res/Pgm/Test. If bit 0 is set in
parameter 430, a soft fault is logged.
If bit 0 is reset in 425 and bit 0 in
parameter 431 is set, a warning fault
is logged. If bit 0 is reset in 430 and
431, no action is taken.
• Bit 1 determines the data output
status of a fault. If set to 0, zeros are
transmitted. If set to 1, the last state
is transmitted.
Check parameter 438 (ChB Flt Sts).
Bit 1=1 indicates a fault if configured
to do so in parameter 430 (ChB RIO
Flt Sel).
Check parameter 439 (ChB Warn Sts).
Bit 1=1 indicates a fault if configured
to do so in parameter 431 (ChB RIO
Warn Sel).
