I have two 24V power supply's both with connected to the same 0V common (and system ground) in addition both supply's are connected to two-stage AC line filter. The analog sensors and analog inputs modules have one of the two 24V power supply and other powers the Unistream HMI and discrete IO.
I checked the power supply's and are with in a (+) 0.4Vdc of the 24Vdc.

During calibration of a pressure sensor (4-20ma) I was unable to achieve an precise calibration 0 to 30.00 PSIA within 0.7 PSIA at the lower or upper range when using the scaling functions.
The sensor was calibrated from the manufacture within 0.1% accuracy.
I decided to check the Analog Input with a calibrated Fluke Processmeter from: 4.000 ma to 20.000ma.
The Hardware was configured for 4-20ma input and default scaling 0 to 8191 inputs with strong filtering enabled. Unilogic version 1.22.13
Here are the results:
Fluke(ma) Actual Count Expected Count Count Diff. 4.0000 -45 0 -45 6.0000 954 1024 -70 8.0000 1954 2048 -94 12.0000 3953 4096 -143 14.0000 4957 5119 -162 16.0000 5951 6143 -192 18.0000 6951 7167 -216 20.0000 7949 8191 -242 The counts are non-linear corresponding to the 4-20ma inputs, i would expect the counts difference to be constant.
I was not able to check all the channels, but could this be just a bad channel or are the values within the specification of the AI card?

We used a MODBUS (SLAVE) Client to Profibus Server(Master) Gateway successfully using Unistream/Unilogic.

I would like to suggest the option of an "OFF/ON/CANCEL" in the Message Box button options in UniLogic. I use the message box to turn OFF and ON; valves, motors and other devices in the binary image properties.
Thanks for listening.

During a recent Unilogics software upgrade my PNG files that I had created were deleted from the Windows 7 Unilogics folders.
I had created a folder...
\ProgramData\Unitronics\Data\UniPics\MyPics
Lesson learned - store your PNG images that you create outside of the \Unitronics\... folders.
Store DTI to file - Append not working with "Only csv"
in UniLogic Software

We have also confirm this issue on one of the newly purchased HMI/PLCs system using the Unilogic firmware 1.28.34 .
We'll use the append option "1" (all files formats ) with the "Store DTI to..." as a work-around until new update is fixed. Thank you for posting.
