CLX Driver
« on: May 04, 2015, 01:02:57 PM »
DigitalPanelMeter and label , when reading floating point value form CLX driver , all will flicker between some unknown value and  a good value,

have 3 panel meters reading temperatures and 2 labels reading temperature setpoints , what happens is that they will all continiously flip between ,
lets say 20 and 6.8976. All will show same value  - 398d seem to work fine, problem  the latest ver g

BevelButtonDisplay will not work now either, data type bool

Label will read timer values ok ,

I tested this out, but not seeing a similar problem. Can you put your PLC into program mode and see if the problem is still there?

Darrel - I've had a similar problem with the display flashing with  3.98g and clx . I put it down to incompatability with vb2010 . Are you on 2010 ?

Is it two floating points? Are they in any kind of array or UDT?

Forgot to mention that I tried it in program mode and same problem , appears to be every time it polls the PLC , I built a HMI that is polling only a MicroLogix 1400 and all is OK , when I add some components for Control Logix 5000 , everything flickers on/off , values from both PLC's.

I've been doing a lot of different testing scenarios, but haven't yet been able to reproduce this on my setup.
