My Program Development Terminal (PDT) has stopped working. What do I do?

November 27th, 2018

Hopefully the circuit boards are just loose inside. Simply remove the top and with the power off, re-seat the cards in their sockets. Replace the top and power on. If this worked, you are indeed lucky, as there are no parts left for the PDT. While your unit is working, we recommend that you upgrade to Logicmaster software which can run on a PC (see How do I communicate to my Series Six PLC on our Series Six programming page). Then when the PDT finally powers down for the last time, you will be prepared for the transition.
