Hi
Can someone explain to me how the memory size limits the size of your program. For example an SLC5/01 has 1K of memory, how many rungs of program would that limit me to, or does it limit the number of Inputs and Outputs I use. If I want to control 12 outputs and 6 inputs, what kind of memory should I have at least and maybe even some spare memory in case I want to expand my program in the future. What's the minimum memory I should go with, 4k, 16k, 32k...
Also is it better to buy a TRIAC output card with SLC500 since I'll have to control coils which operate at 115VAC, or is it better that I use a DC Output card and have Solid State Relays. What's better in terms of money and life expectancy.
What's would I need when putting a SLC500 together, I'm assuming a Power Supply, CPU, Input, Output card. Correct me if I'm missing something.
And final question is what kind of cable is used to communicate with SLC500, is it Ethernet based, and how complicated is it to set up communication with the computer.
I know some of my questions might sound stupid, but I'm really new to PLCs and I would greatly appreciate all the available help and advice I can get from you guys. Thanks for your help in advance.
