Default setting for starting reference of the Slave (DVP-PLC) to be read: H1064 (D100)

example, if D1399 nds to ID1~ID16

d) When both M1353 and M1356 are ON, the station number of ID1~ID16 can be specified by
the user in D1900~D1915 of Master P ample, when D1900~D1903 = K3, K3, K5,

7. Operation:
) Set up the baud rates and communication formats. Master PLC and all connected Slave
PLCs should have the same communication settings. COM1_RS-232: D1036, COM2_RS-485:
S-485: D1109.
