ThingWorx Manufacturing Apps cannot browse into my PLC Tag

I have 2 VMs

VM1. MS Window Server 2016 with ThingWorx Manufacturing Apps and KepserverEX 6.6

VM2. MS Window 7 with RSLogix 5000 and SoftLogix.

These 2 VM can ping each other.

In VM.2,

I create a PLC program, download into SoftLogix and simulate some data.

In VM.1,

I configure the tag in KepserverEx and check the data in OPC Client already.

In ThingWorx Manufacturing Apps, I add new machine and try to configure the KPI.

But in the configuration and setup, when I browse into PLC tag. I cannot see the tag I just add into KepserverEX.

I found just the simulate tag, not tag from SoftLogix.

Cannot find Tag in Kepserver that added from Softlogix
