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)
MMC/SD
The
DinBox RTU M4
has an optional MMC/SD card socket. This memory can be used
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)
FRAM
The
DinBox RTU M4
has optionally 2 FRAM (ferro electric RAM) of 64 Kb (8.192 x 8
bits). This non-volatile memory will be used to store the configuration, measured data,
IEC60870-5-104 events and log information.
See next chapters for more technical details.
