I have 4 thermocoupler modules model 7AT664.70 and I need to configure them to read a type K thermocouple. I have a CP474 and an AF101 analog interface module. From what I saw in the manual, there is a configuration words table, which I don’t know if they are reading parameters or if they must be configured in some way to monitor the module. Every time I connect it and put it in Watch mode, nothing appears on the monitor. Can anyone help me? ![Captura de tela 2024-07-25 091245](https://europe1.discourse-cdn.com/brcommunity/original/2X/4/4dadd8243787b56bc9c35c93f70d06064966df1e.png) ![Captura de tela 2024-07-25 091342](https://europe1.discourse-cdn.com/brcommunity/original/2X/5/53bc0e1c6c8a87ab174d3f1b4ed47a8c606eae6c.png) ---

I assume the IOConfig library must be used [B&R Online Help](https://help.br-automation.com/#/en/4/libraries%2Fioconfig%2Fioconfig.html) to configure the correct Configuration word. But this is very old. ---

Should this library be downloaded externally or do I insert it through the programming code? ---

Right click “Libraries” → Add Object and you should find something like B&R Libraries. ---

Thanks, I managed to add it and I’m trying to program it ---

I added a library and was using B&R support’s own reference programming. I created a program in ANSI C and i started. It gives an error 6024, which says it doesn’t recognize my variable. However, I created it in the command itself and I have already tried to create it in the variable configuration manually. Does anyone know how to solve it? ![Captura de tela 2024-07-31 113051](https://europe1.discourse-cdn.com/brcommunity/original/2X/e/edcfb6596afe059835f48d0c1bd682a8dabbff69.png) ![Captura de tela 2024-07-31 113133](https://europe1.discourse-cdn.com/brcommunity/original/2X/f/f7d5887424627e51800d65cfd76a609fc337a43f.png) ---

Have you switched on local declaration in Project → Settings? ![image](https://europe1.discourse-cdn.com/brcommunity/original/2X/0/0b6e6e569af25ce2600f680be17dfccd64e477c3.png) Or just declare the variable in the .var file, which might be the more common solution. ---
