A.2.5 Carry out record (Record Select)
A record can be started in the status Drive enabled".
This function is usually used for:
 moving to any position in the record list by the PLC
 processing a positioning profile by linking records
 known target positions which seldom change
(formulation change).
Sequence

Up till
the start the controller replies with the number of

accepts the record number and starts the positioning
task.
3. The controller signalizes with the rising edge at Ack_Start
that the PLC output data have been accepted and that the
positioning task is now
active. The positioning command
will be processed irrespective of whether Start_Position
ing_Task has been reset to zero or not.
4. When the record is concluded, MC is set.
