Environment:
MMI Side: Intouch 10, ABCIP.5 connects with one 1756-L71; ABTCP.1 connect with few PLC5 1785-40E
PLC side : 1756-L71 5570 Controller Rev.21.11, 1756-ENBT/A; PLC5: 1785-40E
Studio 5000 V21.00
Almost every half hour (random), I still see the Heart bit is still blinking on Intouch MMI, but the REAL/Float data are not updated. Some time,both Bits and Real data can't be updated.
I resolve the problem by Choosing "No optimization Mode" instead of default "Optimize for read". So far so good after the changes in 4 hours.
I read the ABCIP.5 manual, Page 111-112 is talking about the requirements . But on my side, the L5571 has firmware 21.11, so it does support "Optimized mode".
Anybody has similar case? Any more specific document can be refered for my problem?
Edited: PLC5 connections are always OK. I used ABTCP.1 connects to 3 PLC5 1785-40E.
