Micrologix 1200 and 1500

What is the difference between the 1200 and 1500

i desperately need help li

Here is the link to the micrologix home page. Follow the links to the two types and do your comparison.

There are only one HSC and one PTO in ML1200, versus two of each in ML1500. ML1200 has no internall real-time clock (extra module only).
Their extension modules are not compatible.
The 1500 CPU is a separate piece of hardware that slides into the main unit. It may be with one or two communication ports.
The 1500 main unit may be of different types of I/O.
The 1200 is single unit, one or two ports.
1200 and 1500 main units choise is different by size and I/O type.
These are, generally speaking, all the major differences.

The difference is 300.

That would be a correct assumption -

On the top half of the planet the difference is -300. Now if the question had been phrased the other way around, what is the difference between 1500 and 1200, then the answer would have been 300 for the top half of the planet, and -300 for Alan and our friends downunder.
