Netvar-sender node

Hi there,

I'm using netvar-sender node to send network variable list to my Wago PLC. I have about 145 variables at this moment. When I add one more, the variable don’t arrive at the PLC anymore.
At first I thought a syntax error but then I deleted other (working) variables and it worked again. So I guess I reached a limit somewhere. I put a debug node behind the function that formats the array for sending it and everything looks ok and complete. PLC shouldn’t be the problem either so I’m guessing that the netvar-sender has reached his limit? Does anyone experienced this before? Anybody a suggestion for solution? There will be a lot of variables to add in the future so I’m kind of in trouble…

Thanks in advance!
