Techwayson device driver

Techwayson

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

How to establish connection with TaiLing DX series PLC

1. Hardware connection

Connecting cable:

RS232 (serial port RS232 protocol)

SK HMI COM1/COM2		TaiLing DX series
2	RX	3	TX
3	TX	2	RX
5	GND	5	GND

Terminal of HMI is DB9F, and that of TaiLing DX series PLC is MD8M.

2. Software settings

Select TaiLing Electric in connection device service.

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

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

For setting of the connected PLC, please consult related technical documents of Siemens TaiLing DX series PLC.

3. Operational register and address scope

Register name	Address format	Input scope	Remarks
X	oooo	0 to 377	Bit: input coil, read only
Y	oooo	0 to 377	Bit: output coil
M	dddd	0 to 7999	Bit: intermediate relay
SM	dddd	8000 to 8999	Bit: special intermediate relay
S	dddd	0 to 999	Bit: state bit
T	dddd	0 to 256	Bit: timer state
C	dddd	0 to 256	Bit: counter state
D	dddd	0 to 7999	Word: register
SD	dddd	8000 to 8999	Word: special register
TV	dddd	0 to 255	Word: current value of the timer
CV	dddd	0 to 199	Word: current value of the counter
CV32	dddd	200 to 255	Double-word: current value of 32-bit counter

Register name	Address format	Input scope	Remarks
0x	dddd	1~9984	Bit: output coil
1x	dddd	1~2048	Bit: input coil, read only
3x	dddd	1~512	Word: 16-bit input register, read only
4x	dddd	1~9999	Word: 16-bit holding register

Note：

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

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

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

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

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