DW No.
Bit No.
76543210
Alarm DB 32
Default value: All bits default to 0
K = 0, 4, 8, 12, ... 116 (1st to 30th axis)
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 axes.
2) If the identical bit is also set for operational messages (PLC MD 6043), the PLC goes into
the Stop loop.
Sample application:
DB 32 D 3.3 1 signal error message 8211;
PLC MD 6035.1= 1

Note:
If the identical bit is also set for operational messages (PLC MD 6044-6047), the PLC goes
into the Stop loop.
