Hello Walters;

Here is some of the available info for the LOGO! output swtich times:

This is taken from the Logo_e.pdf, downloable from the Siemens support website.

By the way, many do not consider the LOGO! (and its siblings like the Easy) as a PLC; it is a programmable relay. It does what it does very well, but it has no data manipulation/storage or communications available, which limits its use in control applications.
Hope this helps,
Daniel Chartier

Edit:
Ron, we seem to be on the same wavelength; you're just a little bit faster...
 
okay okay sorry for calling the logo a PLC didn't know its such a sensitive spot but thx for the info.

regards walters
