Koyo device driver | SKTool Manual | Factonation

Koyo

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

How to establish connection with Koyo SN series PLC

1. Hardware connection

Connecting cable:

RS232 (serial port RS232 protocol)

SK HMI COM1/COM2		Koyo SN series
2	RX	4	TX
3	TX	3	RX
5	GND	8	GND

Terminal of HMI is DB9F, and that of Koyo SN series PLC is 6-pin registered jack.

2. Software settings

Select Koyo Electronics 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 Koyo SN series PLC.

Note:

o represents octal system, input range 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
