We need to develop an electronic platafform that can read Modbus RTU and have 4 analog inputs (each can select: 4-20 mA, 0-5 VDC, 0-2400 ohm), 4 binary input and 4 binary outputs. Optional a GPS. We need to be available to send information to a SQL database via 3G/4G and Ethernet. The request is analize (counts, sum, average, integration, etc) of the values of some address via Modbus and or Analog Inputs or Binary Inputs AND send via the communications channels above.
The same hardware must be available to connect to several Modbus Devices (at least 32 devices). The binary input and output have a fix functions to be determinte.
