Z1: NC/PLC interface signals

19.5 Help function output to PLC (H2)

DB31, ...
DBX62.5 Fixed stop reached
Edge evaluation: no
Signal state 1 or The fixed stop was reached after selecting the FXS function.
edge change
This signal is used by analog drives, e.g. to switch the actuator from speedcontrolled to current or
0 → 1
torquecontrolled mode so that a programmable clamping torque can be set.
Signal state 0 or The fixed stop has still not been reached after selecting the FXS function.
edge change
1 → 0

19.5.1

Signals to channel (DB21, ...)

DB21, ...
DBX30.5 Activate associated M01
Edge evaluation: no
Signal state 1 or PLC signals the NCK that the associated M01 (help function) should be activated.
edge change
0 → 1
Signal state 0 or De-activate the associated M01 (help function).
edge change
1 → 0
Corresponding to .... DB21, ... DBX 318.5 (associated M01 active)
19.5.2

Signals from channel (DB21, ...)

DB21, ...
DBB58, M, S, T, D, H, F functions Modification
DBB60 - DBB65
Edge evaluation: No
Signal state 1 or One M, S, T, An D, H, or F function has been output to the interface with a new value together with
edge change the associated change signal at the beginning of an OB1 cycle.
0 → 1 In this case, the change signal indicates that the appropriate value is valid.
Signal state 0 or The change signals are reset by the PLC basic program at the start of the next OB1 cycle.
edge change The value of the data involved is not valid.
1 → 0
