Since there are some applications for which you may not wish to enable these multiple point updates, this facility is controlled via a logical name, ALL_UNSO, which is defined in the CIMPLICITY logical names file.
ALL_UNSO applies to all device interfaces that support unsolicited data except OPC.
Enable a multi-point update function for all device interfaces configured for your system:
Define the logical ALL_UNSO to True by
Add a record similar to the following to log_names.cfg, a text file located in the Program Files\GE Fanuc\Proficy CIMPLICITY\data directory.
Restart the device communications process to make the change active.
Important: In a multi-node system, you need to make this change on the node where the device communications interface is configured to run.
Enable a multi-point update function for a specific device communications interface:
Add a logical
<PORT> corresponds to the CIMPLICITY port for the specific interface.
For the Device Communications Interface, the valid ports depend on the device communications that you are configuring.
If a logical is not defined in the log names file, the default mode, single point update, will apply.
The following native device communications (that are not OPC) support unsolicited data.
