Modbus TCP Communication between Freelance 2013 AC700F and SM500F
Hi. I want to receive data from a ABB SM500F (paperless recorder). It is no problem to set ip adress, but I can‘t set a modbus adress in SM500F because there is no input field for that. In FBD function blocks I have to quote a modbus adress. Many years ago I established another modbus tcp communication to a third-party device that works fine. Kind regards
AFAIK if you set IP Address for Modbus TCP Slave device, you dont need any other address decleration. Maybe you need to use "Uniqe ID" for TCP slave devices, you can use "255" if you dont know exact ID of device. For your FBD block, is it used for Modbus Serial or TCP? You have to be sure first.
