A request was made to add a PLC handshake for stopping shear operations. This will allow a PLC to control the production rate of the line. The PLC must give permission for every shear while in the Run Mode (Automatic). Full documentation on how the Handshaking works is documented in the MODBUS spec.

When waiting for the OK to Shear from the PLC the controller will display "STANDBY" in the run status.
