CX9020 and TwinCAT 2 #41

Closed xavier-1197 closed 3 years ago

Hello PLCHome,

I have a problem with the node-red-contrib-ads module. I can read a global variable in my CX9020 PLC (with TwinCAT 2) but I can't read a variable in a program. I write the right path

Can you help me please thanks

Here you can see my configuration

variable wCTUCv

PLCHome commented 3 years ago

Compteur is not a function block under MAIN. Compteur is a program so "MAIN." leave out and it should go "Compteur.wCTUCv". The writing will blocked by twincat 2. Reading goes.

You can see it with ADS symbols. There are flow examples in read.me.

Thanks a lot @PLCHome That works. The example

node red contrib ads

took me down the wrong path.

It makes perfect sense now
