Simple Math! - insyncs - 30-03-2017

Hi can you help please,
 
Trying to compute some simple math in the ewon but I’m not getting anywhere with it.  Have looked through reference manual,  but cannot find a math example.
 
“Running_Hours%” is a Dword,  “ComAp_Running_Hours_MSB%” is an INT “ComAp_Running_Hours_LSB%” is an INT
 
I cannot get any values from the calc into the “Running_Hours” tag, even if I use Running_Hours% =1
 
The % needs to be added at the end of the Tag as per the manual for an INT – doesn’t cover a DWord so % is probably wrong, have tries without also.

Code in basic IDE:


Code:
$Running_Hours% = (65536 * $F_Running_Hours_MSB%) + $F_Running_Hours_LSB%



All I want to do is put two 16bit values into a 32bit word.  

Cheers

There is no need to put a $ char in front of the variables unless it is a local variable of a function (which is not your case).

See an example that works :



Code:
F_Running_Hours_MSB% = 195
F_Running_Hours_LSB% = 80

Running_Hours% = (65536 * F_Running_Hours_MSB%) + F_Running_Hours_LSB%
PRINT Running_Hours%

Hi,

Thanks for the response. It doesnt work for me.

a bit more info for you. the two tags below are modbus tags:

F_Running_Hours_MSB%
F_Running_Hours_LSB%

I want to read the values from the modbus tags, then create a 32 bit value stored into Running_Hours%( Local memory variable?)

hope that's clear?

PS can you help me change my username so its not my email!

Cheers

ok got there thanks.

i some how deleted the format of the script template so i guess it wasn't being called.

this is what i used in the end thanks.

// Calc For Historical Report
Running_Hours_MSB% = Running_Hours_MSB@
Running_Hours_LSB% = Running_Hours_LSB@

Running_Hours% = (65536 * Running_Hours_MSB%) + Running_Hours_LSB%
F_Running_Hours@ = Running_Hours%
PRINT Running_Hours%
// Calc End

If you could let me know about the username that would be grand.
