Transferring auxiliary functions -M-, -H-, -S-.
5.4 Transferring auxiliary functions -M-, -H-, -S-.
The M and H functions are transferred per channel. Transferring S functions does not depend
on the channel.
When executing a block that contains M, H, S functions, the following information is
transferred to the PLC.
Transferring -M- functions.
The CNC assigns the numbers of the M functions programmed in the block to registers
MFUN1 through MFUN7. Some M functions have an associated function (DMxx) that is
activated when sending the M to the PLC.
The CNC activates the general logic output MSTROBE to "tell" the PLC that it must execute
them. This mark is kept high (=1) for a time period indicated by parameter MINAENDW.
Depending on the type of synchronization, the CNC will either wait or not for the general input
AUXEND to be activated indicating the end of the PLC execution. The type of synchronization
is defined in the machine parameters
The CNC cancels the general logic output MSTROBE to conclude the execution.
Transferring -H- functions.
The CNC assigns the numbers of the H functions programmed in the block to registers
HFUN1 through HFUN7.
The CNC activates the general logic output HSTROBE to "tell" the PLC that it must execute
them. This mark is kept high (=1) for a time period indicated by parameter MINAENDW.
After this time period, the CNC considers its execution completed because there is no
synchronization.
When sending several blocks in a row just having H functions, the CNC waits twice the time
indicated in parameter MINAENDW.
Transferring -S- functions
The CNC assigns the values of the S programmed in each spindle to registers SFUN1
through SFUN4.
The CNC activates the general logic output SSTROBE to "tell" the PLC that it must execute
it. The CNC waits for the general input AUXEND to be activated indicating the end of the PLC
execution.
The CNC cancels the general logic output SSTROBE to conclude the execution.
