I have made a simulation of two robots doing conveyor tracking. These robots, as well as their tool paths, are identical. One robot can run contentious cycles, while the other stops after one cycle. Each robot is set up with its own conveyor. The error messages I get is: IRB\_2400\_20kg\_1.55m\_1 (Station): 10002 - Program pointer has been reset 18-12-2015 12:30:13 Event Log IRB\_2400\_20kg\_1.55m (Station): 10002 - Program pointer has been reset 18-12-2015 12:30:13 Event Log IRB\_2400\_20kg\_1.55m\_1 (Station): 10011 - Motors ON state 18-12-2015 12:30:13 Event Log IRB\_2400\_20kg\_1.55m\_1 (Station): 10052 - Regain start 18-12-2015 12:30:13 Event Log IRB\_2400\_20kg\_1.55m\_1 (Station): 10053 - Regain ready 18-12-2015 12:30:13 Event Log IRB\_2400\_20kg\_1.55m\_1 (Station): 10151 - Program started 18-12-2015 12:30:13 Event Log IRB\_2400\_20kg\_1.55m (Station): 10052 - Regain start 18-12-2015 12:30:14 Event Log IRB\_2400\_20kg\_1.55m (Station): 10053 - Regain ready 18-12-2015 12:30:14 Event Log IRB\_2400\_20kg\_1.55m (Station): 10151 - Program started 18-12-2015 12:30:14 Event Log IRB\_2400\_20kg\_1.55m\_1 (Station): 10122 - Program stopped 18-12-2015 12:30:21 Event Log What do these error messages mean?
