Appendix C Use Ladder Logic To Perform Run Time Services and Reconfiguration
The following ladder-logic example shows how to change the High and Low
engineering values (scaling parameters) for an analog output module in
Slot 3 of the local chassis.
Rung Description
0 This rung moves new Channel 0 scaling parameters to the configuration portion
of the structure associated with an analog output module in Slot 3 of the local
chassis.
The new values move at the user’s discretion (represented by the user defined
XIC instruction) after making sure the desired new high value is not equal to the
desired new low value. This rung only moves the data to the configuration
portion of the structure but does not send it to the module.
1 This rung sends the Reset Module service to the analog output module. Upon
receipt, the module will initiate a hardware reset on itself, behaving as though
it has just been inserted into the system. A connection is established and the
new configuration parameters are sent.
