When you develop a program using multiples of your own funtion block, it creates separate instances of the function. It is similar to drawing a flow chart or digital logic diagram.

It was my first time using function block programming, but I found it very intuitive. I recently did a large project, which I developed some fantastic Function blocks which made the job soo much easier, and are reusable on any future projects. The esiest software to program the quantum with is modsoft.however it will only work in dos and does not work with newer versions of windows.all said and done modicon is o.k.i am still pushing the plant to change to ab and it looks like some people are taking notice now that modicon has made there 984 series redundant.(The plant is only 7 years old and now cannot get spare parts for there plc).If you have any spefic questions let me know.i will try and help.also how are you going to comunicate? MBplus.Modbus? or serial? RE: Schneider Modicon Quantum PLC ScottyUK (Electrical)ĩ5% of my work is AB, but I think Modicon Concept is the best programming tool after using AB for so many years.

I am currently updated a plant to the quantum series controller.If the program you are going to be using is in ladder then the differences are not to bad.(I was trained on allen bradley and got thrown into the modicon almost the same way you are!.it took a while but now i find it difficult to program ab!).modicon uses similar function blocks and instructions.timers and counters are different as well as reseting.however the modicon beats ab hands down when it comes to on line editing.there is no difference between on and offline as far as its uld be a good thing or bad thing depending on what you do!.i would imagine you are going to be using the pro worx software which i find is similar to rs logix 500 or 5000 although it is not quite as freindly.
