M171 EPPROM Parameters issues

[Ross1993]

I'm using a TM171OF22R in Machine Expert HVAC. Not sure if anyone has seen this before but when using the Simulator, upon downloading application to the Sim all of my EPPROM variables are defaulting to max values and ignoring the assigned default value? Even BIOS parameters are doing this. I haven't been able to test outside the Sim as I don't have the Hardware. I even tried to created a completely new project with none of my code. Created EPPROM variables:

VAR1      Unsigned 32       UDINT

VAR2      Unsigned 32       UDINT

There was no code attached to these variables and all I did was download to the Sim and when read both the variables were  reading 4294967296. Both of these had default values of 0 with no min or max values and no scale.

Hi,

have you done a download all of the project (first big icon on the top from the right)?

At the end of the procedure a popup should open asking if you want to write all the default values.

If you download just the source the EEprom status is not changed (a new EEprom is initialized at 16#FFFF)

Or as decimal value -1
