Is Modbus serial / TCP (ethernet) communication possible with the Zelio logic modules?
Both Modbus Serial and Ethernet communication are possible but only with Zelio logic SR3 modules supplied with 24 VDC (SR3B... BD).
The SR3MBU01BD communication extension must be used for serial, or SR3NET01BD for Ethernet Modbus / TCP.
For more information on using this module, refer to the Zelio SR2/SR3 catalogue. You can find this, along with other relevant documentation, on our website www.se.com/uk/
