8.8.2 Configuration of T functions
Transfer and
acknowledgment of
T function
MP_type specifies the type of tool call.
Use the parameter MP_condition to define the conditions for the output of
the T strobe.
There are two possibilities for transferring the T strobe to the PLC and for
acknowledgment by the PLC:
Transfer and acknowledgment with MP_signal
• Transfer of the S strobe: The PLC marker defined in MP_signal is set.
• Acknowledgment of the S strobe: The PLC marker defined in
MP_signal is reset.
Transfer with MP_signal and acknowledgment with MP_acknowledge:
• Transfer of the S strobe: The PLC marker defined in MP_signal is set.
• Acknowledgment of the S strobe: The PLC marker defined in
MP_acknowledge is set.
HEIDENHAIN recommends that you only use MP_signal for transfer and
acknowledgment.
If MP_signal and MP_acknowledge are not defined, the data of the S strobe
is saved without synchronization with the PLC program. The output is
immediately acknowledged.
