In the tools section you can change this repesentation to "X and Y" if you prefer. This is determined by the setting up of the I/O table. In the symbols editor the input/output is also shown with the rack and slot position. With respect to analogues and the I/O map, if you set up an I/O table in the "IO Table And Unit Setup" section in the left hand section of the screen, CX-Programmer will automatically place "I and Q" in front of inputs and outputs for you. Sub routines are similar to other PLCs in that the sub routine is only active when called.
Tasks can be turned on and off and are only scanned when turned on, thus reducing scan time to only the running tasks.
Omron cx programmer addressing software#
I must say that I came up with DOS software and was used to a very long program in one section, although I still structured the program into similar blocks in the very long section of ladder.Īnother useful way of programming provided is "tasks". It is a way of "structuring" the program into like routine blocks and is quite useful for another person when trouble shooting a machine or process. The program is scanned from top to bottom section by section as if the whole program was in a very long block. I then normally write my shut down alarms into the next section etc etc. Quite useful - I normally start with a setup section for writing values to be used in the program (values into data memories on the first scan flag). They are not sub-routines, tasks or anything else but program broken into usable pieces. These sections are just a way of breaking up the program into organised "chunks" if you will.
When you speak of sections I presume you mean the "sections" that can be named with routine or process names down the left hand side of the page. I do not have a problem with you contacting me though as I may miss a topic otherwise due to work pressures and locations.ĬX-Programmer offers a multitude of programming options and at first these can be confusing. I have placed the enquiry in the open forum as many more people may contribute and/or learn from the exchange. The other problem is that I normally do my checks after dinner and a bottle or 2 of "big" Ozzy red wines. Snail mail is pretty painful when accustomed to cable broadband and I try to use it as little as possible. Sorry to have been so long responding but I just checked a few things while working out of town and have just returned. You can email me at if you dont want to use the interface. But where does the analog data end up? Thanks alot. How do you address analog inputs and outputs? I see that the digitals are 0.001, 1.002, etc. Does it do this automatically? No need to use SBS calls? I just want the program to scan all the sections from top to bottom. Anyways, you say you dont use them, how do you get the program to scan the diffent sections? ie, I have a main section, a Z1 heat section, door sections, ect. I came across a post you had on sub-routines, and thought id give you a try. Im mostly an AB guy, and ive just started a program for a CJ1 plc. I was wondering if you would be willing to give me a few pointers on using cx-programmer.
