As a system integrator for golf course irrigation system, customer A provide a complete remote control solution which includes pump station, PLC, gateway and remote monitoring capabilities. To achieve efficient management of golf courses, a remote control and monitoring solution is required:
- Remotely turn on/off pump stations based on weather, golf course conditions and etc.
- Monitor real-time Allen-Bradley PLC data via VNC/HMI
- Conduct remote PLC programming and maintenance
Traditional Solution for Remote Irrigation Control
Traditionally, a remote network is built between remote site and engineers via global IP address.
- Motors inside the golf pump station connect to the Allen-Bradley PLC via Modbus.
- Onsite PLC, HMI and Windows PC connect to InRouter900 VPN gateway via Ethernet.
- InRouter900 connects to the Internet via global IP address.
- InRouter900 enables private IP to global IP mapping.
- PC and mobile devices access HMI web service and conduct remote PLC programming.
- VNC client accesses Windows IPC remote desktop.
The traditional solution has the following issues:
- Network access via public IP address is exposed to various network attacks including port sniffing, DDoS. When network attack occurs, access to onsite PLC/HMI is not available.
- Unencrypted business data can also be attached by hackers.
- For system integrators, getting public IP address is difficult and costly, especially in developing countries.
InConnect is a simple service which build a secure remote network easily and cost-effectily.
- Motor - PLC connection and configuration unchanged.
- InRouter900 VPN gateway connects to the internet via 4G LTE or ADSL, with no global IP address required.
- InRouter900 adds InConnect configurations and connects to InConnect server automatically.
- With InConnect, PC, mobile devices and VNC client can access onsite PLC/HMI directly for remote monitoring and control.
