Hello Everyone,

I’m trying to write a remote tag value from one Ignition gateway to another. I have performed this activity earlier with two gateways running the **same Ignition version** , and it worked correctly after enabling **Service Security → Tag Access → Read/Write** on the remote gateway.

In my current setup, one gateway is running **Ignition 8.3** and the other is running **Ignition 8.1**. I have applied the same Tag Access settings, but I’m still unable to write the remote tag value.

Is this issue related to the **version difference** between the gateways, or are there additional configuration steps required for cross-version remote tag writes?

Any technical guidance would be appreciated.

Which direction are you trying to write? I know 7.9 to 8.1 had some issues in the 7.9 to 8.1 direction...

Had the same question. Take a look at this thread.

> Found it mentioned in the Upgrade Guide. 8.3 won’t sync to 8.1 over the gateway network.
