Hello this is my first post go easy on me please.
I am having an issue with a panelview 1000 (2711-T10G1) i am getting an error "661 Timeout- no block transfer writes" The panelview communicates with the 1747-L532c/d 5/03 CPU through a 1747-sn RIO Scanner. There is also a Wonderware PC/HMI connected to the programming port on the PLC communicating through (DF-1 I think) But The Wonderware updates with no issues. Level is polled by wonderware and a Volume calculation is done and sent back to the plc and then written to the panelview. The #F and #N are COP to #M0 to write to the panelview instead of BTW because BTW is not supported. The #N seem to update on the panelview but the #F do not.
If power is cycled to the panelview or i restart from the system pages the floats will update once but not continuously. If I disconnect the Wonderware PC, the Panelview Will update the last value calculated in Wonderware and I can change the value in rslogix500 data table and it updates on the panelview.
I changed one of the read/write registers in wonderware and then MOV it to the register written to the panelview in case the read/write tags in wonderware was the issue but did not make a difference. Also the operators tell me this problem comes and goes for months at a time....
