Hi
I am a beginner within the PLC world. But I want to learn as much as possible. So here are som questions based on the product information about Beckhoff's CX9020.
It runs with a Processor with these poroprties: ARM Cortex™-A8, 1 GHz. What does the abreviation ARM stand for? What is Cortex, other than a company and/or brand name? What does -A8 means?
1 GHz means 1 billion Hertz. But what does that figure correspond to in reality?
The information says that the number fo cores are 1. Is the core the same thing as the brain of the Central Processing Unit (CPU)?
What is a flash memory?
It says that its flash memory has these properties: 512 MB microSD (optionally expandable), 2 x microSD card slot
Are there any other types of flash memories than microSD wihtin the PLC world? If so, which are there?
It has an Internal main memory with 1 GB DDR3 RAM. What does 1 gigabyte correspond to in terms of plc programming rungs/commands/etc?
RAM is an abrevation för Random Access Memory, to the best of my knowledge. But what does DDR3 mean?
Its persistent memory is 128 KB NOVRAM integrated. What does 128 000 bytes correspond to in terms of plc programming? What does NOVRAM stand for?
Its interfaces are 2 x RJ45 (Ethernet, internal switch), 10/100 Mbit/s, DVI-D, 4 x USB 2.0, 1 x optional interface.
Ethernet is ordinary network cable. I also know what USB is. But what is DVI-D and 2 x RJ45?
Its I/O connection is E-bus or K-bus. What is a E-bus and a K-bus?
