5.4.1 Synchronized transfer.
This type of transfer takes place with the S function and with the M functions set with
synchronization.
When the PLC is requested to execute several M or S functions at the same time, the
corresponding SSTROBE or MSTROBE signals are activated; but the CNC waits for a single
"AUXEND" signal to end all of them.
Transferring -M- functions
1 The CNC indicates in registers MFUN1 to MFUN7 of the channel the M functions
programmed in the block and it activates the MSTROBE mark so the PLC executes them.
2 The PLC must deactivate the AUXEND mark to let the CNC know that the execution has
begun.
3 Once the required auxiliary functions have been executed, the PLC must activate the
AUXEND mark to let the CNC know that the execution has ended.
The AUXEND mark must be kept high (=1) longer than the time period established by
parameter MINAENDW.
4 After this time, the CNC deactivates the MSTROBE mark thus ending the execution of
the functions.
Transferring -S- functions
1 The CNC indicates in register SFUN1 to SFUN4 the S value programmed in the block
and activates the SSTROBE mark so the PLC executes it.
2 The PLC must deactivate the AUXEND mark to let the CNC know that the execution has
begun.
3 After selecting the requested S, the PLC must activate the AUXEND mark to let the CNC
know that the execution has ended.
The AUXEND mark must be kept high (=1) longer than the time period established by
parameter MINAENDW.
4 After this time, the CNC deactivates the MSTROBE mark thus ending the execution of
the function.
