Alarm channel DB
Alarm channel DB
Default value: All bits default to 0
Bit = 0 The system software does not evaluate the bits in the corresponding interface
byte for error messages.
Bit = 1 The system software evaluates the bits in the corresponding interface byte for
error messages.
Note:
The bit applies to all channels. If the corresponding bit is also set for operational messages
(PLC MD 6040/6041), the PLC goes into the stop loop in the startup routine.
Sample application:
Error message evaluation when a DR8 bit is "1": PLC MD 6032.5=1
Bit 9.5 in channel 2 (DB 11) results in output of error message number 6145 (see PLC
Installation Section).

Default value: All bits default to 0
K = 0, 4, 8, 12, 16, 20 (1st to 6th spindle)
Bit = 0 The system software does not evaluate the bits in the corresponding interface
byte for error messages.
Bit = 1 The system software evaluates the bits in the corresponding interface byte for
error messages.
Notes:
1) The bit applies to all spindles.
2) If the corresponding bit is also set for operational messages (PLC MD 6042), the PLC
goes into the stop loop in the startup routine.
Sample application:
DB 31 D 7.9 1 signal error message 8021;
PLC MD 6034.0= 1 (See PLC Installation Section)
