According to my own understanding of most PLCs, summarize the implementation process of PLC remote communication with most 232 interfaces or 485 interfaces.

[System Composition]

Using PLC- GPRS IP MODEM remote communication system, the basic structure is as follows:

Panasonic PLC equipment transmits data to four-signal DTU through 232 interface. Four-signal DTU uploads data to host computer software by using Internet and public mobile network, and host computer software can monitor data of field equipment.

[Implementation method]

[Hardware]

1. AFPX-C30T (PLC CPU unit)

2.AFPX-COM1(PLC RS232 communication card)

3.F2103(Xiamen Sixin GPRS IP MODEM)

4.SIM mobile phone card (GSM network, GPRS service needs to be opened)

5. wireless router

[Software]

IP Modem Configure (GPRS IP MODEM Configuration Software)

2.TCP2COM(Virtual Serial Port Software)

3.FPWINGR(Panasonic PLC programming software)
