Posted 20 May 2021

Hi,

we have a Mitsubishi PLC Fx3U-128MT and a A&D weighing module AD 4212L.

The weighing module supports MODBUS RTU communication via RS-485.

We are looking for the most affordable and simpler way to establish communication between PLC and weighing module.

At pag 20 of the manual " MODBUS Serial Communication Edition " https://dl.mitsubishielectric.com/dl/fa/document/manual/plc_fx/jy997d26201/jy997d26201g.pdf

there are three options of communication equipment.

According to your experience, what specific interfaces do you suggest us to invest in? Thanks
