Omron CJ1M memory area ?
Omron CJ1M memory area ?
(OP)
Hi, I have been working with Allen Bradley products for the past few years. Now I'm starting with Omron. I'm lost.
I'm using CX-One to program a CJ1M 11 CPU. The manuals are not clear at all.
What I need to know is the memory area. What are the different files used for?
How are my digital inputs addressed?
My digital outputs?
My analogue inputs?
My analogue Outputs?
My internal bits?
My internal INT?
My internal Reals?
If I want to adresse a bit within an INT or word?
What about Timers & Counters?
I'm used to B3:0/0
N7:0/1 or N7:0
T4:0/dn
So on and so forth.
Any help would be apreciated.
Thanks
Ray

The CJ1/CS1 processors have CIO (common I/O area), W (work or internal bits and words), HR (memory retentive I/O area), DM (data memories or registers - these are all memory retentive and need to be reset to clear data).
Counters and timers are pretty simple but there are a variety of them. In the setup from the start, you can actually set up your timers and counters to be either BCD or decimal based. All timers and counters are then set up to the base you have chosen.
For analogue cards etc, you really need to get on line and create an I/O table to make things easy for yourself. CX-Programmer will then automatically allocate the address range to the analogue card. You can read and/or change the address area from the I/O table section. You can also set up your comms cards from there.
By the way, if you can get on line to the PLC and create the I/O table, CX-Programmer will show you the addressing for each card in the I/O table section. You can then go in a re-address any card to any area of the CIO table. You can even go in, when on line, and adjust the time delay for each individual I/O card. This can be quite handy to suppress noise.
I could go on for ever but I hope you get the general idea.
Have fun. It is a really great little PLC.
