Inovance device driver

Inovance

The device driver is used for SK series HMI to read and write the data or state of Inovance H1u/H2u series PLC register. The serial communication connection is established through the serial port of HMI and the serial port of Inovance H1u/H2u series PLC, so as to operate Inovance H1u/H2u series PLC. Prior to use of the driver, one shall carefully read related technical specifications of the chapter and Inovance H1u/H2u series PLC.

How to establish connection with Inovance H1u/H2u series PLC

1. Hardware connection

Connecting cable:

RS232 (serial port RS232 protocol)

SK　HMI COM1/COM2		Inovance H1u/H2u series
6	RX-	4	TX-
7	RX+	7	TX+
8	TX-	1	RX-
9	TX+	2	RX+

Terminal of HMI is DB9F, and that of Inovance H1u/H2u series PLC is DB9M.

2. Software settings

Select Inovance 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 Inovance H1u/H2u series PLC.

3. Operational register and address range

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

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
