Execution channels<br />
4.4.2 Non-synchronized transfer.<br />
This type of transfer takes place with the H function and with the M functions set without<br />
synchronization.<br />

EXECUTION<br />
Transferring -M- functions<br />
1 The CNC indicates in registers MFUN1 to MFUN7 of the channel the M functions<br />
programmed in the block and it activates the MSTROBE mark so the PLC executes them.<br />
2 The CNC keeps the MSTROBE mark active for a time period indicated by parameter<br />
MINA<strong>EN</strong>DW.<br />
3 After this time, the CNC goes on executing the program regardless of the time required<br />
by the PLC to execute that function.<br />
Transferring -H- functions<br />
1 2 3<br />
MINA<strong>EN</strong>DW<br />
1 The CNC indicates in registers HFUN1 to HFUN7 of the channel the H functions<br />
programmed in the block and it activates the HSTROBE mark so the PLC executes them.<br />
2 The CNC keeps the HSTROBE mark active for a time period indicated by parameter<br />
MINA<strong>EN</strong>DW.<br />
3 After this time, the CNC goes on executing the program regardless of the time required<br />
by the PLC to execute that function.<br />
Considerations for transferring these functions.<br />
The value of parameter MINA<strong>EN</strong>DW should be the same or longer than the PLC program<br />
execution period parameter PRGFREQ in order to ensure that the PLC detects that signal.<br />
When sending non-synchronized H or M functions corresponding to consecutive blocks of<br />
the same program, the CNC waits between blocks for a time period indicated by MINANEDW<br />
so the PLC can read all the functions.<br />
