This video shows an example of how to connect to a PLC using InduSoft Web Studio HMI and SCADA sfotware. The PLC in this case is a WAGO 750-841 Programmable Fieldbus Controller using the MODBUS/TCP protocol.
It’s important to note that WAGO PLCs may differ slightly from other PLCs using the MODBUS/TCP protocol. Most MODBUS and MODBUS/TCP devices start their addressing at 4X:1, whereas the WAGO controller starts its holding register addressing at 4X:12289. Continue reading
