Priming switch data

You can prime your I/O configuration in a work IODF with the switch serial number for the active processor. For the prerequisites for this function see Prerequisites

To prime, select the action Prime serial number from the context menu (or action code  i ) on the Switch List.

The Confirm Priming Switch List shows the selected switches with the sensed data for the switch types, serial numbers, switch control units, and switch device numbers, and their corresponding definitions in the IODF.

Note:
Only one defined switch control unit and one defined switch device is shown even if several have been defined. If the sensed switch control unit and device is one that has been defined, it will be displayed. Otherwise the defined switch control unit and device with the lowest control unit number will be displayed.

An update of the switch serial number also updates the serial number of the corresponding switch control units and switch devices.

The sensed data for the switch serial numbers are shown on the Confirmation panel, and can be accepted, or rejected before being incorporated into the IODF. If a value is blanked out, the defined IODF value is not changed. If you use the F12=Cancel key, none of the sensed values is used.
