Delta device driver

Delta

The device driver is used for SK series HMI to read and write the data or state of Delta DVP series PLC register. The serial communication connection is established through the serial port of HMI and the serial port of Delta DVP series PLC, so as to operate Delta DVP series PLC. Prior to use of the driver, one shall carefully read related technical specifications of the chapter and Delta DVP series PLC.

How to establish connection with Delta DVP series PLC

1. Hardware connection

Connecting cable:

RS232 (serial port RS232 protocol)

SK HMI COM1/COM2		Delta DVP series
2	RX	5	TX
3	TX	4	RX
5	GND	8	GND

Terminal of SK series HMI is DB9F; that of Delta DVP series PLC is MD8M.

RS485 (serial port RS485 protocol)

SK HMI COM1/COM2		Delta DVP series
8	TX-	B
9	TX+	A

Terminal of SK HMI is DB9F, and that of Delta DVP series PLC is two-wire terminal.

2. Software settings

ü Select Delta Corporation in connection device service.

ü Select the corresponding item in connection device service according to the connected PLC model or supported protocol.

ü Ensure that the communication parameters in touch screen connection parameters and PLC station number are consistent with the PLC connected.

ü For settings of the PLC, refer to the technical documents of the Delta DVP series PLC.

3. Operational register and address range

Register name	Address format	Input range	Remarks
X	ooo	0~377	Bit: input connection point, read only
Y	ooo	0~377	Bit: output connection point
M	dddd	0~4095	Bit: auxiliary relay
S	dddd	0~1023	Bit: internal relay
T	ddd	0~255	Bit: timer status
C	ddd	0~255	Bit: counter status
D	dddd	0~9999	Word: temporary data storage
TV	ddd	0~255	Word: current value of timer
CV	ddd	0~199	Word: current value of counter
CV32	ddd	200~255	Double words: current value of 32-bit counter

Note:

d represents decimal system, input range is 0-9;

o represents octal system, input range is 0-7;

Bit in the remarks: represents the register can only used as bit;

Word in the remarks: represents the register can only used as word;

Double-word in the remarks: represents that the data type of the register in configuration must be 32-bit;

Read only in the remarks represents that the register can only be read but not be written;

The names of the registers supported by different equipment model may be different, and the scopes may also be different.

For detailed name and scope, please consult related technical document of the connected device.
