Scout PLC

Overview

The Scout PLC enables reading input values from a PLC (or any Modbus RTU device) and writing analog and relay control values to a PLC. The connection to the PLC uses the serial connector on the Scout. The protocol is Modbus RTU, where the Scout is the Master and the PLC and other devices are Modbus slaves.

The Scout PLC communicates with 12 or 24 registers in the PLC or Modbus device.

The I/O in the PLC can be any combination of analog (holding registers) or digital points (coils, inputs and status).

Values that are read from the PLC are compared against user-defined limits or changes of state. When those rules are violated, the Scout PLC starts calling up to 8 phone and/or pager numbers to notify personnel of the alarm condition.
