The Target Tag can be either entered manually or selected using the Tag Browser in the PLX50
Configuration Utility. The Tag Browser requires the controller to be available on the network.
To browse to the tag, click on the Browse button. The Tag Browser opens and scans all the
tags inside that controller. If the controller has been recently scanned in this session, then a
cached version of the tags will be displayed. A rescan of the tags can be triggered by selecting
the Refresh button in the Tag Browser’s toolbar.
Only tags of a relevant type will be enabled, guiding you to select a suitable tag.
NOTE: When mapping PLC5 Boolean files (e.g. B3), it is recommended that the
destination Logix tag be a SINT array, rather than a Boolean array. Using the
latter may result in unexpected results due to the packing format of Logix
Boolean arrays.

NOTE: It is youra responsibility to ensure that the Logix tag array datatype and
size matches that of the selected DF1 Data Address. Failing to do this can result
in communication faults and unexpected results.
