pedro.jdacunha Posts: 5 Rating: (0)	Hi all, i have an OP77A with something like 600 Alarms and some additional information. This Panel is in a large Profibus network. Now the problem is: everytime the alarm trigger shots i have the error 50000 and 50001. I already have given 5 seconds to the alarm refresh but the error is still appearing. Have i too many alarms in this panel or the problem could be anything else? In the WinnCCFlexible Help i found this explanations to the following errors: 50000: The HMI device is receiving data faster than it is capable of processing. Therefore, no further data will be accepted until all the current data has been processed. Data exchange then resumes. 50001: Data exchange has been resumed. I really don't know what can i do to solve this. Can anyone help me. Thanks in advance

Maybe you should change the device, because the OP77A are not the fastest panel! The problem are that you did not know what Data are send to the panel, so you can only test it. But if you sure that the problem comes from the "fault messages", then you can try to buffering the messages in the plc. Good luck....

pedro.jdacunha Posts: 5 Rating: (0)	Theres no problem to change to OP77B? i mean the hardware isn't exactly the same... Buffering the messages in the PLC isn't a possible solution. Thanks for help
