Status Relay Controller Overview

The Status Relay Controller (SRC) is a mini PLC programmed to work with DataXchange.  The SRC comes pre-programmed and ready to work with DataXchange out of the box.  Every SRC is programmed identically and the configuration is done with the expressions.  DataXchange will poll the SRC and retrieve the status of each of the inputs and assign the status values to the SRC variables so they can be used in expressions. 

The Standard SRC has 8 inputs.  By default all 8 Inputs are be used for Equipment Status and each of these inputs are mapped to a variable allowing standard DataXchange expressions to be used to evaluate the status of the attached equipment.  The SRC can be configured to have the an input used for a part counter and have that input associated with the SRC part count variable.

The Extended SRC has 8 additional discrete inputs as well as 4, 4-20 milliamp input connections.  The additional discrete inputs can be used to track additional points on the machine such  returning a High or Low value to the SRC.  Another feature is allowing any of the extended 8 digital inputs to return data as an integer within DataXchange.  There is more detail on the integer conversion here.

Both versions of the SRC have 6 outputs and each output is mapped to a continuous and pulsed variable allowing standard DataXchange expression to be used to control devices connected to the SRC outputs.
