Since there are some applications for which you may not wish to enable these multiple point updates, this facility is controlled via a logical defined in the CIMPLICITY logical names file. This file is located in your project's \data directory and is named log_names.cfg.
To enable this multi-point update function for all device interfaces configured for your system, define the logical ALL_UNSO to True by adding a record similar to the following to this file:
Since this file is a text file, you can add this record with any text editor. After the edit has been completed, you need to restart the device communications process to make the change active. In a multi-node system, you need to make this change on the node where the device communications interface is configured to run.
Alternatively, you can enable this function for a specific device communications interface by adding a logical
where <PORT> corresponds to the CIMPLICITY port for the specific interface. For the Allen-Bradley Device Communications Interface, the valid ports are ABINT0, ABINT1, ABINT2, and ABINT3.
If a logical is not defined in the log names file, the default mode of single point update will apply.
This logical applies to all device interfaces, which are based on the CIMPLICITY Device Communications Toolkit. This applies to those interfaces provided by GE Fanuc as well as those developed by third parties.
Important: If you use OPC Client device communications, do not configure the ALL_UNSO logical. Instead, use the <PORT>_ALL_UNSO parameter.
