Address Name Type Initial Value Comment
100.0 CHGDIF_P DINT L#5000 Switchover difference plus
104.0 CHGDIF_M DINT L#5000 Switchover difference minus:
108.0 CUTDIF_P DINT L#2000 Switch-off difference plus
112.0 CUTDIF_M DINT L#2000 Switch-off difference minus
8.8.3 Incremental Dimension Number 255
Incremental dimension number 255 also allows you to set the distance.
You transfer the switch-off differences and the switchover differences together with
the incremental dimension. In contrast to the other incremental dimensions,
incremental dimension 255 uses the value for the switch-off and switchover
difference specified in the channel DB. The entries from the machine data have no
validity for this incremental dimension.
