Byte No.
Description
Byte 12
Reserved for expansions
Byte 13
Bit 0: flags are stored in the NOVRAM (1)/are not stored (0)
Bit 1: PLC run time measurement on (1)/off (0)
Bit 2,3: terminal bus/PLC cycle sequence
0: terminal bus inputs before PLC cycle, terminal bus outputs
after PLC cycle
1: terminal bus inputs and outputs before PLC cycle
2: terminal bus inputs and outputs after PLC cycle
Bit 4: Nominal cycle time and background execution time are
set via TWinCAT BC / TWinCAT PLC (1) / are set via
UserPrmData (0) (Byte 43: Nominal cycle time, Byte 44:
Background execution time)
Bit 5: BC state is copied into flag (1) (PROFIBUS state into flag
byte 508,509, terminal bus state into flag byte 510,511) / is not
copied into flag
Byte 14
Bit 0: 1
Bit 3: in the event of a PLC STOP, the affiliated terminal bus
outputs remain unchanged (1)/the affiliated terminal bus
outputs are set to 0 (0)
Bit 4: in the event of a terminal bus error, the affiliated PLC
inputs remain unchanged (1) / the affiliated PLC intputs are set
to 0 (0)
Bit 5: in the event of a field bus error, the affiliated PLC inputs
remain unchanged (1)/ the affiliated PLC inputs are set to 0 (0)
Bit 6: in the event of a PLC STOP, the affiliated DP outputs
remain unchanged (1)/the affiliated DP outputs are set to 0 (0)
