Convert word type in boolean

[orla090978]

Dear all,

From PLC I receive a tag in word format via S7+ driver.
I'd like to split this word in 16 tags boolean to use these bit splitted.
How to convert these tags in WinCCOA?
Is it recommended to create a script or create a para.pnl ad hoc?
Does it afflict performances?

Thanks a lot
Best regards

There are several possibilities to split a word into its bits:
-- Address configuration with a subindex for the address (if supported by the driver)
-- Address configuration on the node of type "struct" + datatype (driver splits the word automatically in its bits)
-- Using a dp function
-- Writing a script

Please have a look at the following post in another thread:

Thanks for fast reply.

Do you know if S7 + driver support subindex configuration?
Do you know if DP function can slow the system performance?

Have you an idea about script (always for this purpose) and when it shall be triggered?

Thanks a lot.

The S7Plus driver does not seem to support subindexes, but perhaps slice access is possible.

A DP function will increase the event manager startup time a little bit.
