Simple Math!

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.

Yes, I can.
Now I changed it to marcus_insyncs.
Tell me whether it is ok or not.

Yes, I can.

Hi,

Can you change it to just insyncs?
