ModBus AOI Studio 500 issues

[turner15429]

Has anyone had an issue with modbus inputs going High ever few minutes with a AB client AOI? I'm receiving discrete inputs from an automation direct P2000 PLC to a compact logix controller using ModBus TCPIP. It works well but every now and then i see all my inputs go high for a split second.

If you map a handful into read registers, do those values change state?
