We have six sites for SCADA, and the customer wants to monitor all the sites through one central site. Each site is 200 km away from other sites. All the sites are at remote location and there is no telephone line or GSM connectivity. Please suggest the best and economical communication solution for this SCADA installation plan.

There a multitude of solutions for this application, unfortunately I would need very specific information before a specific response could be provided.

Motorola Moscsad, Allen Bradley, Siemens and other PLC / RTU manufactures, Motorola and MDS radios - communications, IFix, Wonderware and such for SCADA software. Your project requirments and budget will determine a lot regarding the equipment and other aspects of the system - alarms, solar sites or not, controls, computer system, ect.

Since the sites are relatively close, you could go with solar powered sites, utilized spread spectrum radios, Motorola Moscad-L RTU's, IFix software.

If you require specific services, I would be pleased to provide the required consulting services and based uopn your project requirements a detailed quote. Contact me off line at:

Sounds to me like there is no best or economical solution to this issue based on what you have stated. You may well have to settle for what you can get.

For the most economical solution is that you can use narrow band radio transivers.
If you have PLC at your remote stations be sure that you have ethernet network at your remote stations as well as central station.
Your radio transiever conntected with ethernet network one at central and others at remote sites . Each PLC at remote sites must have a unique IP address.
About HMI intellution is the best as far as scada
connectivity is concern.
About PLC I think you can use SIEMENS S7 315-2DP with CP 343.

If you have no other means of communication use
packet radio

If you have TCP you may use
for process visualization.

How about exploring VSAT? Several references exist of using VSAT for SCADA related communications.

Ever hear of Meteor Communications ??
Visit their site at

Might sound like a strange communications technology, but it works great !!
