Installation and Programming Instructions
Before starting the remote reprogramming procedure, a telephone connection between the Controls Engineer and the Technician at the machine site must be maintained at all times through out the process.

To begin the process at the machine, a telephone line or suitable line for a fax machine/PC connection allows the Modem to reprogram or service a PLC control panel from a remote location. The technician at the control panel will take the following steps to prepare the control panel to be serviced from a remote location.

o Plug the 120VAC Adapter to the PLC Access ® Modem, and into a 110-outlet source.

o Connect the telephone line to the RJ-11 phone jack on the Dixon Access® Modem.

o Connect a programming cable (as specified by Allen Bradley, G.E., or Automation Direct, see list above) to the PLC (programming port), and to the DB-9 connection port on the Dixon PLC Access® Modem.

o Make sure the machine control is in "manual mode" for the servicing process.

o Inform the Control Engineer on the telephone that the control is now ready for the reprogramming process.

The technician must stay at the machine while the Control Engineer (at the remote location) makes the necessary changes to the control circuit. The technician must ensure that conditions at the machine are safe before cycling the machine during the reprogramming process. It may be necessary to remove tooling, various mechanisms, etc. to avoid any accidental machine damage during the reprogramming procedure.
