Set all tag values to 0 before disconnecting the device

Hello,

I am working with an Omron NJ101 PLC. I have a problem where, when the device is disconnected, the tags freeze with the last known value. I want all tag values to be set to zero when the device is disconnected from KEPServer, and restored when the device reconnects.

Does anyone know how to achieve this?

The requested feature is not natively supported. However, if you could share the reason or use case behind wanting to camouflage the values, we may be able to suggest an alternative approach.
Additionally, could you please let us know which Kepware driver you are currently using?

Hi,

I am using the Omron driver. I collected data from an Omron NJ101-9000 PLC.
My system setup is:
PLC (Omron) → KEPServerEX (Omron driver → Data Logger) → ODBC Data Sources (32-bit) → MySQL Server

When I disconnect the device from KEPServerEX, I get data that looks like this:

The red color indicates the time when the device was disconnected. You can see that the data is 'frozen'.
I want the data to be set to zero when the device is disconnected.
