Explanation: Counted value output
The counted value typical always adds the newly formed difference value
(difference between the new and last received counted value) to the value
currently output at the counted value output.
The counted value output is a double word in which the counted value is
stored in BCD format or as a 32-bit integer value (depending on the
"BCD_Format" parameter, see above).
The counted value id always output as a positive number. If the maximum
counted value that can be represented is exceeded, the counted value starts
again at 0 and counting continues in the positive numeric range.
Since the parameter is an in-out parameter (IN_OUT), the value can be reset
to 0 or another value at the counted value output by the user program at any
time.
5.7.1.14 Data typical Dat12D_S
Function
Send maximum of 12 double words with any data content.
The content of each double word may be a value in double word (DWORD, DINT, REAL)
format, it can also be a mixture of other data types which together form a double word, for
example:
● 4 bytes
● 2 words
● 2 bytes + 1 word
Sending the data area can be triggered in two ways:
● By a change check
The data is transferred as soon as a bit changes ("SendOnChange" = TRUE).
● By the user program
The transfer can be triggered by an edge change 0
→ 1 at the "TriggerInput" input
For time-driven transfer FC Trigger can be used.
With "SendAll" you can also specify whether the transfer always includes all data or only the
data double words that have changed.
