Analog Module Application Case
1. Expand module through the host PLC parallel port
.................................................................................................................................... 9
1.1. Module power supply
...........................................................................................................................................................................9
1.2. The analog need't be written any conversion program, read the analog register value directly.
............................................ 9
1.3. Programming skills
............................................................................................................................................................................10
1.4. Display analog value on SCADA, HMI
........................................................................................................................................... 10
1.5. When the engineering value is not used, the default code value is 0 ~ 32000
........................................................................11
1.6. Module CR code application example: Read the module channel disconnection alarm
........................................................11

Software operation steps
.................................................................................................................................................................13
2.6. Remote IO application example(RS485 mode): The PLC read the 4 communication temperature values of S04AI
module
......................................................................................................................................................................................................... 15
2.7. Remote IO application example (RS485 mode): The PLC writes the 8-channel output values of S08AO module
...........15
2.8. Remote IO application example(Ethernet mode): PLC read and write each channel input and output values of S08XA-e
16
2.9. Haiwell Cloud configuration communicates directly with S08AI module example
