Issue Details

When using NI OPC Server 2016 to communicate with the Omron NJ501-1500 PLC, setting some tags data type as 'Double' gives the following notification:

       Omron FINS Ethernet

       Data type 'Double' is not valid for device address 'D13404'.

This notification is shown in the following dialog box:



NI OPC Server CJ2 address doesn't support 'Double' data type. You can change to the 'Float' as a workaround.
