So, I was able to bring up the TED Computer IPD program and it displayed real time elevator operation for car A,B. I was also able to inject car and hall call up & dn and the two cars would dispatch a car to answer the call However, car C would not allow me to see it's current status of operation and would not answer a hall call. The car would work normal inside the car but would after a while without a demand would park at the 2nd floor for a longer time and then closed doors and maybe answer a hall call or just go on a random trip to the top or bottom floors.
The TED system displays POWER DOWN and BALANCED under it and when I tried to select car C the system shows that car C is OFFLINE.
I was thinking that this group is and maybe always was operating in this manner and really who would have ever really noticed this unless they were trying to capture this car by sending the other cars away.
This 3 car Group is hooked up as a serial link communication which has wires to each car to and from the main car and to the TED computer display. I hope that your answer about the third car being a slave car is exactly what's happening and it is working as intended. I was headed to load weighing problems, maybe not. I agree these 3 car groups are the worst for a really busy building. Thanks for the feed back to both of you. .
