Several HMI manufacturers (e.g., Eaton, PROFACE, etc.) support the CODESYS V3 Ethernet driver, which can be used with a WAGO PLC to read and write tag data.
The driver utilizes the CODESYS symbol configuration file, allowing you to program the HMI with the same tags used in the PLC program. This reduces development time and improves accuracy by eliminating the need to enter tag names twice or use any mapping translations.
This document uses a PROFACE HMI, but HMIs that support the CODESYS V3 Ethernet driver will import and use the tag data in a similar manner.
