To connect to the control center, instead of an integrated UMTS modem the Simatic RTU3010C uses external industrial routers such as Scalance M for network connection over an Industrial Ethernet interface. This lends greater flexibility when it comes to choosing a communication medium, with scope for mobile wireless network or wired network connection for instance over DSL. Power is supplied to both the compact RTUs over a DC12-24 volt interface, by a solar panel with rechargeable battery or simply using conventional batteries. The RTUs are also capable of powering the connected sensors. The new firmware version 2.0 enables additional batteries to be used, increasing the capacity to more than 70 ampere hours (Ah) and allowing significantly longer operating times without the need to change batteries.
Its robust design allows the RTU to be used under harsh ambient conditions at temperatures of between -40°C and +70ºC, and when fitted with an additional IP 68 rated protective housing, even under flood conditions. The RTUs can be remotely configured and updated with new firmware via web-based engineering. As the new firmware version V2.0 supports autoconfiguration in Sinema Remote Connect, the VPN connections to the RTUs can be simply configured using this management platform for remote networks.
