Crashing on writing to variable

[kempmaritz]

Ever since upgrade to v2.0.2 the node crashes Node-red when I write a value to the PLC. I have an S7-315 with ethernet card (343-1)

Here is a snippet of the code that causes the crash.

Can you help with this please? Was working perfectly for the last year.

I've imported your flow and the variable you're writing to is not listed in the "Variables" tab (changed its name probably?). This shouldn't crash Node-RED, but the flow at least won't work.

Even though, could you please provide the logs of Node-RED when the problem happens?

I'm getting the following after I write a value to the PLC:

This was an issue of the underlying nodes7 library that has already been fixed. Closing the issue for now
