Connection Parameters Needed for HMI/cMT Products to Communicate with Delta Electronics DVP Series using EBPro (EasyBuilder Pro)

HMI Settings

Parameter	Recommended	Options
PLC type	DELTA DVP
PLC I/F	RS232	RS232, RS485
Baud rate	9600	9600, 19200
Data bits	7	7, 8
Parity	Even	Even, Odd, None
Stop bits	1	1
PLC sta. no.	1	0–255

Support communications between HMI and PLC in pass-through mode.

Set LW-9903 to 2 to enhance the speed of download/upload PLC program in pass-through mode.

PLC Settings

DVP-SS2 RS485 baud rate 19200 or higher must set D1038 (Data Response Delay Time).

D1038: Setting value range 0–20 (time unit: 0.1 ms)
