Kepware Bad Data Quality for Variable Data Tags

[JP_10607974]

I am setting up an Atlas Copco MTF6000 controller using the KEPServerEX Torque Tool Ethernet driver. I am expericing an issue seeing Variable data in the OPC Quick Client. Some addresses, such as COMM_CONTROL_SER_NUM display data and display 'Good' quality. However, another tag with an address of format 1202.30237 does not display data in the OPC Quick Client and shows 'Bad' Quality. 

The Torque Tool Ethernet Driver help page uses 1202.30237 as an example of Variable Data addressing, but I am unable to determine why this does not display data. In fact, I have this issue for all MID.PID address formats.

Does anyone have any ideas? Am I addessing the tags correctly?

It appears as though you may have addressed the Variable Data tag incorrectly. To allow access to these values, the format of the tag addresses needs to be “MID”.”PID”.”Step”.Unit as outlined on the page of the Kepware help file in the following link:

I would also make sure you are running  the latest KEPServerEX release (V6.13), since newer MID's have recently been added to the driver.

I recommend opening a support ticket with the Kepware Technical Support Team if you are still having an issue after the recommended change. Here is a link to My Kepware portal where a support ticket can be logged:
