Support Questions / Error stops hmi execution

« on: August 02, 2021, 06:50:41 AM »

I have a prototype hmi (laptop for now) connected to a chiller via modbusRTU.
Sometimes the chiller will be powered down while the Hmi si still powered up.
When this happens I get an error on the hmi screen 'convert from string 'setpoint' to 'double' is invalid.
I get it, the reply from the modbus (corrupted or none) is not compatible with VB.
However I dont want the hmi to give the option to quit, the operators will foul things up.
Can I handle the error or stop the do you want to quit message?

Support Questions / Auto boot project on power up

« on: August 01, 2021, 07:12:18 AM »

I want to find a way to boot the project on power up, operators here are not that bright.
I tried using publish bit soon found thats not the way to do it.
Is there an .exe I can run or some settings to change to get the thing to run the project on power up?
Not had any replies to my other question, I wonder if this forum is still active.

Support Questions / Gauge component, show an integer to 1 decimal place

« on: July 28, 2021, 09:43:33 AM »

I'm using the gauge function to show a temperature, it comes from the controller as temp X 100, so 1 is 0.01% and 100 is 1%and so on.
I set the scale factor to 0.01 which displays the temp to the nearest degree, then I tried to set numeric format to 0.0 but I get a type error, presumably because the variable is a integer not a float.
Can I get the gauge to show 1 decimal place?
