When you perform a write operation to ABCLX device in V7 the value seems to flicker between old value and new value before updating to the new value. The issue is caused because the  driver has responded to say that the write succeeded, but has not updated its cache (i.e. has not yet polled the device again) before the IOConnector polls it again.



The issue only occurs in Version 7.0 and if you are running ABCLX driver version or before. This issue has been fixed in version ABCLX_3.03.08.004
