zASCII mode (COM3: M1320 = OFF, COM1: M1139 = OFF):

When X0 = ON, MODRW executes the function specified by Function Code H10 PLC ÖVFD-B, PLC sends: “01 10 2000 0002 04 1770 0012 30” VFDÖPLC, PLC receives: “01 10 2000 0002 CD”

(No processing on received data)

zRTU Mode (COM3: M1320=On, COM1: M1139=On):

When X0 = ON, MODRW executes the function specified by Function Code H10 PLC ÖVFD-B,PLC sends: “01 10 2000 0002 04 1770 0012 EE 0C” VFD-BÖPLC, PLC receives :＂01 10 2000 0002 4A08＂
