Cortex M4 processor
All RTU functionalities are automatically guided by the M4 processor with the proper
firmware. This processor will/can control the following tasks ;
- Real Time Clock
- communication with the Sierra Wireless GSM module
- TCP/IP stack
- read AD converters to measure AI voltages
optionally calculations on measured or received data
-
- DI changes scanning
- set DO's
read/write Modbus slave(s) connected via the RS485 interface
-
- FRAM memory will be used to store IEC60870-5-104 event data
write and read data in/from the MMC/SD memory (optional)
-

to store firmware code, configuration, measured data and log information.
IO
This RTU has 2 analog inputs, 2 digital outputs and 8 digital inputs.
2 x AI - not galvanically isolated (- connection = GND)
8 x DI - galvanically isolated (optocoupler)
- active inputs (with internal 24Vdc dc/dc convertor)
2 x DO - galvanically isolated (opto mos 'solid state' relay)
