Modifying S/N Parameter of a MODBUS RTU Device via KepserverEx

[VC_11347114]

Hello everyone,

I’m seeking guidance on a specific issue I’m encountering with a MODBUS RTU device connected through KepserverEx.

Previously, we communicated directly with the device, and we were able to modify its serial number (S/N) using a custom-built frame. However, we’ve since transitioned to using a KepserverEx server for communication, and I’m unsure how to perform the same operation in this new setup.

Here’s the current situation:

1. The MODBUS RTU device is successfully connected and communicating through KepserverEx.
2. We have access to the following suites in KepserverEx: IoT Gateway, Modbus, and Advanced Tags.
3. I can unlock the device's electronics and enable it to enter the mode required to modify the serial number.
4. The issue lies in accessing and modifying the S/N parameter via the KepserverEx server.

Thank you in advance for your help! Any pointers or guidance will be invaluable.

Best regards,

Hello,

The Modbus Serial Driver supports standard function codes as per the manual (refer to the section "Function Codes Description"). Are you referring to a custom-built frame with a function code other than those specified in the manual?

I recommend opening a support ticket with the Kepware Technical Support team to better understand the issue and provide a quick and effective resolution. Here is a link to the My Kepware login page where a ticket can be submitted:
