HI @A_10333884 ,

Have you verified that tag which have created in Kepware with Number related Data Types of Float, Long, Word .., to that property? Because if kepaware data type is not matched with Thingworx property base type means after you bind that tag with thing property, it will automatically change the base type based on kepware tag.

Thanks & Regards,

Hi,

Sorry, i accidentally clicked accept as solution.

Yes i already checked it, i chose default, but when i opened the tag in Quick Client, it showed me that the tag data type is float.

It should works. If Possible, Can you please share your snapshots of Kepware Tag details and Property bindings with Thingworx Thing for more clarification?

Hi,

Can you please choose basetype as float for 1 Kepware tag property as per PLC Address? Also try to disconnect the exist binding of that property from Thingworx & check the thing property basetype is Number and then do re-bind it . Meanwhile you please let me know in which type of channel you have created those device tags?

Thanks & Regards,

Hi,

In kepware, if the tag quality turns to bad after the changing the basetype means better to check with that PLC team / program for data type configured in that PLC address.

Additionally, if you want to view the actual data types of PLC tags in kepware means while creating of device itself you can do Right Click on Device > Tag Generation > Create Tags it will automatically create the tags with groups once PLC is connected with Kepware device.

Thanks & Regards,
