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