Data interface between the remote device and the control center
At remote and dispersed processes there is often an issue of establishing communication with the control center and between the processes themselves. RTU Unit (Remote Terminal Unit) implements an open-standard protocols and enables connectivity of field devices with the control center via the mobile network.
The unit has a built-in 4G LTE modem that provides a communication link between the control center and the remote system. Radio modem can be connected to USB port, protocols enable connectivity between devices and systems from different manufacturers.
The following features are supported in the ME-RTU.
|DNP3 connectivity||DNP3 slave Level 2|
|Ethernet, Serial (via USB to RS232 converter)|
|IEC 60870-5-101/104 connectivity||IEC 60870-5-101/104 slave support|
|IEC 60870-5-104 master to IEC 60870-5-104 slave gateway|
|IEC 61850 connectivity||IEC 61850 Client to IEC 60870-5-104 slave gateway|
|PLC iQ-F/Q/L series connectivity||L series and Q (SN11012 or later): Socket communication|
|Q (before SN11012): Fixed Buffer communication|
|iQ-F series: Socket communication|
|SMS messaging||BFM value triggered SMS message with dynamic values in text|
|Time synchronization||User defines where the time synchronization should be made from. Options are: PLC, SNTP servers, DNP3 or IEC 60870 Master (Controlling) stations.|
|Integrated I/Os||2 module digital inputs and 2 module digital outputs used as an expansion for the PLC IOs|
|Online PLC programing and monitoring||Online PLC programing and monitoring via cellular or local network|
|File transfers||FTP, SFTP|
|PPP||PPP for serial/USB modem connections|
|IT functionality||DNS, DDNS, SNMP, HTTP|
|VPN functionality||For secure communications|
10% less energy consumption due to more effective control, 15% less congestion on the remote devices, and a 20% reduction in management costs because of remote control.
Fields of application
Control and management of remote systems: aqueducts, pipelines, transformer stations, switching stations, road tunnels and wastewater treatment plants.
