Read access on pre output value "path" in combination with synchronization mode not allowed.
Description | There is a programmed read access with V.G.M_FCT[<M_Nummer>].PRE_OUTP_PATH or V.G.H_FCT[<H_Nummer>].PRE_OUTP_PATH on the early output that can be read as lead distance P-CHAN-00070 in mm or inch. This read access is not permitted since the corresponding synchronization mode of this M/H function is not of type MEP_SVS (P-CHAN-00041).
Response | Class | 2 | Abort NC program processing.
Solution | Class | 3 | Set synchronization mode MEP_SVS in the corresponding M/H function and define path advance with P-CHAN-00070. Then, in NC program, a read access with V.G.M_FCT[<M_Nummer>].PRE_OUTP_PATH or V.G.H_FCT[<H_Nummer>].PRE_OUTP_PATH is possible.

Note:

The current synchronisation mode can be read with the variables

V.G.M_FCT[<M_Nummer>].SYNCH

or

V.G.H_FCT[<H_Nummer>].SYNCH

Hint:

Parameter | %1: | Error value [-]
Identifier of the programmed variable
%2: | Current value [-]
Identifier of the techno function
%3: | Current value [-]
Current synchronization mode of the M/H function
%4: | Current value [-]
Number of the M/H function
Error type | 1, Error message from NC program.
