Fault text and
code:
Suggested action: Description:
Fault
type:
ChB
Res/Pgm/Test
36024 Soft,
warning,
or none
The PLC Communications
Adapter Board has detected the
PLC controller being switched
from the run mode to another
mode.
Check the PLC mode switch and the
I/O control reset. Clear the fault by
issuing a Clear Fault or a Drive Reset
command, or by recycling the 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 430 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 0=1 indicates a fault if configured
to do so in Parameter 430 (ChB RIO
Flt Sel).
Check parameter 439 (ChB Warn Sts).
Bit 0=1 indicates a fault if configured
to do so in parameter 431 (ChB RIO
Warn Sel).
ChA Rack Fault
36025 Soft,
warning,
or none
The PLC Communications
Adapter Board has detected that
the PLC controller either has its
rack number (rack address)
inhibited, or is no longer
scanning the rack.
Check if the PLC has its rack inhibited.
Check if the PLC is scanning the rack.
Check the rack address on the PLC
Communications Adapter Board.
Refer to the table in Chapter 2 to verify
the DIP switch settings.
ChB Rack Fault
36026
Soft,
warning,
or none
The PLC Communications
Adapter Board has detected that
the PLC controller either has its
rack number (rack address)
inhibited, or is no longer
scanning the rack.
Check if the PLC has its rack inhibited.
Check if the PLC is scanning the rack.
Check the rack address on the PLC
Communications Adapter Board.
Refer to the table in Chapter 2 to verify
the DIP switch settings.
