There is a tag named Frequency.Frequency 1 (s) you can use with NO contact

You can use inverted contact of "General.Ladder Initial Cycle" as a condition to store from your HSC to a global tag.

Look at Help and search Interrupts immediate. There you find related information. I´m not sure if your selected HM+PLC will be able to handle that functions.

Yes you can, thise Samba model comprises two RTD/TC inputs. https://www.unitronicsplc.com/support-technical-library/

Take a look to "Load Timer/Counter Current" option under Store menu.

Puede intentar usando la función MODBUS #6 (preset holding register) en lugar de la #16. Algunos dispositivos esclavos no pueden procesar todas las funciones MODBUS

You need set jumpers for current analog input and current analog output, did you?

CopyMemory reads 4 consecutive addesses (long type). Column defined as Timer needs 4 bytes (integer type). I don´t remember the reason I read 4 long registers to read timers, but it works.

I´ve read timers from datatables using VBA in Excel using this code: Call CopyMemory(resultLong, DB(lAddress * ElementSize + 23), 4) resultSingle = resultLong / (24 * 60) resultSingle = resultSingle / (60 * 100) Workbooks(NombreArchivoDatos).Sheets("Referencias").Cells(lAddress + lRowReadIndex + 2, 4) = resultSingle Workbooks(NombreArchivoDatos).Sheets("Referencias").Cells(lAddress + lRowReadIndex + 2, 4).NumberFormat = "[hh]:mm:ss.00" lAddress and ElementSize depends of RAM address of specific datatable you want

If you use CopyMemory function to get data directly from PLC memory address, then use PtrSafe in declaration of module: Private Declare PtrSafe Sub CopyMemory Lib "kernel32" Alias "RtlMoveMemory" (Destination As Any, Source As Any, ByVal Length As Long)

The rung you show is disabled, then is not asigned preset to T0

Version 1.28.34 does not change date modified. I also expect that any file just opened without any modification saved, is not changed its modified date.

Right click on desired jump condition, then Clear jump option

I just realized that npn/pnp field exists. I never had to change it before. Is it really relevant or just to visual indication?

Note that initialize resets all memory to zero and if you have set some important values like PID parameters they will be all deleted. I find it useful only in new projects downloaded to used PLC.
