Title: Micro800 series array tag name
Post by: thunting on July 13, 2020, 02:15:56 PM

Hello,
I'm testing AHMI to use on our plant floor. I'm not experienced with VB. The PLC is a Micro850. I'm using the EthernetIPforMicro800Com driver.

I'm trying a basic tag read and write HMI with a button and a label using the Properties / PLC Properties dialogue. I can read / write to the 1 dimensional array SensorGPM[1] without a problem. I can read / write to the 2 dimensional array Recipe[1,1].

Trying to read / write to the 2 dimensional array Recipe[RecipeSelect,1] results in invalid tag name. Both tags a global. I must have the formatting wrong, can someone please help me out?

Thanks

I assume RecipeSelect is a tag in the PLC. The PLC cannot decipher tags embedded into another.

You must first read the value of RecipeSelect, then use that value

Dim RecipeSelectValue as string = EthernetIPforCLXCom1.Read("RecipeSelect")
Dim RecipeValue as string = EthernetIPforCLXCom1.Read("Recipe[" & RecipeSelectValue & ",1]")
