Hartelijk bedankt, I think you're right. I use floating point and every time you multiply or do something you have type a number along the lines of 10.0. I've used an number of ST function blocks, mostly all of them use a fair bit of floating point math. I totally forgot that in NL we use the comma as a decimal seperator. I only lived there the first 18 years of my life, give me a break. Thanks, I let you know how it works out. Arjan

A heads up to to the people who are not aware of it. Dell sells the latitude D630 and it has an actual serial port on the back. No card reader & webcam options etc., but I really like mine. It also has the non shiny screen (matte) which is imo nicer for every day use. It's a 14.1" screen with 1400x900 resolution. Vista ultimate gives me no problems with CX-One by the way. Mine came with both XP & Vista. XP was installed and instead of upgrading I installed Vista next to XP. All works fine. I've also seen a PCMCIA serial adapter, I think that installs as an actual hardware serial port not an emulated one.

Thanks anonymous, I switched to Omron recently. I've been using CP1Hs sofar. I used to use the S7-200 through the microwin software. I was used to Function blocks where you loose the internal variables every time it scans through the function. I am really liking the structured text function blocks, I started programming basic, pascal, & C++ back in the 80's when I went to school. I am using the edge detection for a counter, counting the edges if P_1S. It's an easy way to create your own timer.

That's a slick way of doing it. Should the InternalReset be an external value, or will it maintain its value as a internal value. Just wondering since it is a function block.
