Record select (positioning mode)

A positioning task in Record select mode is written with one
record of nominal values.

A record can be started in the status “Operation enabled”
with the record number. 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

1. Set the desired record number in the output data of the

master. Up till the start the controller replies with the
number of the record last processed.

2. With a rising edge at START (CPOS.B1) the controller ac-

cepts the record number and starts the positioning task.

3. The controller signalizes with the rising edge at Quit 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 (CPOS.B1)
has been reset to zero or not.

4. When the record is concluded, MC (SPOS.B2) is set.
