Record start sequence

1 Set the desired record number in the PLC’s output data. Until

the start, the CMAX responds with the number of the record
last executed.

2 If SPOS.ACK (Acknowledge start) = 0, the PLC can intitiate

execution of the record with a rising edge at CPOS.START.

3 The CMAX accepts the record number and starts positioning.

The actual record number is set to the new record in the PLC
input data and SPOS.MC is reset.
