7 Configuration for: Read Input Status / Response.

Click on the left-hand side on the relevant function and you get the windows on

the right.

Result: All values are displayed in hexadecimal (when changing the values you

can enter in decimal and it will be automatically changed into hexadecimal).

There are 5 sub menus of the response:

1. Slave address

Default is the Modbus address of the MC32 (decimal 32 = 20 hex)

2. Function

Command 02 (read input status)!

3. Byte count

Number of bytes (see query): 40 bits / 8 = 5 bytes!

4. Data length is 5 bytes (see 3)

Data location is 7, because "Read coil status" starts at 2 and needs 5 bytes

5. Checksum

Do not alter
