Inverse engineering to a plc omron cj1m cpu13

[fofig 0]

I have a plc omron cj1m cpu13 with: power supply cj1w pd025, cpu unit cj1w-cpu13, 2 modules E/S cj1w-ID211 0.00-0.15 and 1.00-1.15, 4 out modules cj1w-OD212 2.00-2.15*3.00-3.15*4.00-4.15*5.00-5.15 and 2 modules cj1w-TS562 of temperature. I connect me with him and download the program, but I need understanding the same. I do not understand as they link the entered physicses with symbols in the program. please help me, I need know.

Symbols are references to a specific addresses. Double click "Symbols" from the project tree. There are 2, Global and Local. Also if you can not see the addresses in the ladder diagram, check the Options. Select "Tools > Options > Ladder Information". Make sure "If name empty" is NOT selected under "Show Address".

Thank you very much for taking interest , but I need to know like to relate the direction to the entrance and or exit in the rack cj1w ID211 or cj1w OD212 , if some definite method is necessary to he depends on the manufacturer or if that the user defines it , for example: Do I eat would name him the entrance 0 of the first module ID211?? Do I eat would name him the entrance 0 of the first module ID211?? thank you

I'm trying to understand your question. The ID211 and OD212 may be installed in either order. If you have an existing program then you must install them properly. See both configurations below: Edited 24 Jul 2015 by IO_Rack

Please forgive me for my translation to English, it was an error not to check the answer. My objective is to be able to understand as an entered or physical exit in the rack relates with the symbol or direction. Never before I have elaborated a program, but I have read very much to be able to accomplish this work, all bibliography says that the first thing is to define the symbols, but nobody says or puts an example of the correct mode to do it. I need to know the correct mode to declare in that a switch connect the rack's entrance for example, to be able to identify it next in the program. In this way I believe than pus reading the program that I have in front the other way around and that I not elaborate . I believe in that to the less Thank you very much for your help

Let's say you have a button in the electrical drawing that is named S1 and that the ID211 is the first IO module on the plc, then you can insert the name you want for it in the symbols (either global or local). In the Symbols you have a column that is called name, and one that is called comment. The name holds whatever name you want for the IO and cant have any spaces in the name. The comment can have spaces in it.
