Multiple Point Updates via a Logical Name (ALL_UNSO)

About this task

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:

Procedure

  1. Define the logical ALL_UNSO to True by
  2. Add a record similar to the following to log_names.cfg, a text file located in the Program Files\Proficy\Proficy CIMPLICITY\data directory.

    ALL_UNSO|P|default|10|true

  3. 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>_ALL_UNSO|P|default|10|true

    Where

    <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.
