HaiWell device driver

HAIWeLL

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

How to establish connection with HAIWELL device

1. Hardware connection

Connecting cable:

RS232 (serial port RS232 protocol)

SK HMI COM1/COM2		HaiWell E/S/H series
2	RX	2	TX
3	TX	1	RX
5	GND	3	GND

Terminal of SK series HMI is DB9F, and that of Haiwell E/S/H series PLC is MD4M.

2. Software settings

Select Haiwell Technology Corp. in connection device service.

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

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

For settings of the PLC connected, refer to the technical documents of the Haiwell E/S/H series PLC.

3. Operational register and address range

Register name	Address format	Input range	Remarks
X	ddd	0~1023	Bit: External switch input
Y	ddd	0~1023	Bit: External switch output
M	ddd	0~12287	Bit: Internal relay
SM	ddd	0~215	Bit: System status
S	ddd	0~2047	Bit: Step status
T	ddd	0~1023	Bit: Timer status
C	ddd	0~255	Bit: Counter status
AI	ddd	0~255	Word: Analog input register
AQ	ddd	0~255	Word: Analog output register
V	ddd	0~14847	Word: Internal register
TCV	ddd	0~1023	Word: current value of Timer
CCV	ddd	0~47, 80~255	Word: Current value of counter
SV	ddd	0~154	Word: System register
CCV32	ddd	0~31	Double word: Current value of counter

Note:

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

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

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

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.
