We are using a Flexy connected to an AllenBradley PLC. The IO Server is a DF1. The tags we are referencing are with an address starting with the letter L, such as L45:10.
When we set the tags up with a csv file and import into the Flexy unit then the tags are working just fine.
When we try and change the tags using the web interface of the Flexy unit the error will pop up for the tag address.
