HEIDENHAIN MANUALPLUS 620 - 7.8.2 24 V- switching input;outputs

January 2012 7.8 PLC Inputs/Outputs 1365
7.8.2 24 V– switching input/outputs
In PLC addresses you can find the current states of the switching inputs and
outputs.
For the current states of the inputs/outputs of the external PL:
 Read all inputs with Module 9002
 Update all outputs with Module 9005
With Module 9004 you can evaluate the rising or falling edge of the PLC
inputs.
If all PLC outputs are switched off (e.g., during PLC program compilation or
due to a PLC run-time error), the outputs defined via the configuration object
CfgPlcDeferCutoff can be switched off delayed by a time between 0 and 5
seconds. The delay only affects outputs that cannot be switched off by an
emergency stop, since for the outputs that can be shut off by an emergency
stop, the 24 V supply is shut off immediately.
MP_port
Number of the physical output port on the PL
Available from NCK software version: 597 110-02.
Format: Numerical value
Input: 0 to 31
Default: No value, parameter optional
Access: LEVEL3
Reaction: NOTHING
MP_time
Delay time during switch-off
Available from NCK software version: 597 110-02.
Format: Numerical value
Input: 0.1 to 5.0 [s]
Default: No value, parameter optional
Access: LEVEL3
Reaction: NOTHING
Note
Before the PLC program is converted, the PLC outputs are reset. In
addition, the memory of the PLC outputs is reset.
During a loss of power (power fail), the control tries to reset the PLC
outputs.
