omron plc addressing

HI EVERYONE Can please tell me what is the addressing: input o(zero) ch 8 bits input 1ch 8 bits output 10ch 8 bits output 11ch 8 bits Thanks in advance Mike

Addressing for the CIO (AKA the IO area) is as follows: Channel #.bit number So, the input channel bits are: 0.00 - 0.07 and 1.00 - 1.07 the output bits are: 10.00 - 10.07 and 11.00 - 11.07 Hopefully that helps.

Thanks for the reply .You did clear my confusion. Mike

One follow up statement: the bit numbers in the address are in decimal format. So, if you have 16 pt modules, the bits after 0.09 are 0.10, 0.11 ... 0.15 (as opposed to 0.A, 0.B ... 0.F)

HI MICHEAL I have a CP2MA as a single unit as mentiond before 0Ch, 1Ch, as input and output as 10Ch and 11Ch but when the uploaded is reviewed noticed there are output as 18.3, 18.2, 18.1,18.0, and some as inputs 11.00 ,11.01. I do not understand how these are created if outputs are10.00 to 10.07 and 11.00 to 11.07 then where 18.0 comes from. my other question is it possible that out put is created in the program but not wired to terminal so the input of the output is used somewhere in the program as a input. THANKS A LOT

In the PLC the channels [words] assigned to I/O is just memory area that maps physical Inputs and Outputs to the processor. If you have no physical I/O at certain memory addresses they can be used in the program as "Virtual" I/O.

hi guys, im newbie of OMRON ... im using cx-programmer , master module start with PA202 , CJ2M-CPU12 , CRM21 , ID231(0000-0003) , ID231(0004-0007) , OD231(0008-0011) , OD231(0012-0015) connect to 1 unit of CRT1-MD16(0016) CH5? isit the address is correct?

Hi Alvis, Each 231 ID/ODs only uses 2 Words For the CRT1/CompoNet unit, you need to consider the Unit No. of the master (CRM21), and the communication Mode being used, which can be selected using the rotary switch. If you aren't using Mode 8, it should be around CIO 2000s. Also the node address for the CRT1-MD16 will relate to the actual addressing Edited 3 Sep 2015 by innoaloe

hi innoaloe , thanks for replying my noob question. each ID/OD card using 2 words.... Means - PA202 , CJ2M-CPU12 , CRM21 , ID231 (0000.0>15 - 0001.0>15 ) , OD231(0002.0>15 - 0003.0>15 ) And then CRT1-MD16 is mix input and output slave.. CIO-2000.00 > 07 input ? CIO-2000.01 > 07 output ? or CIO-2000-00 > 07 input , CIO 2000-08 > 15 output? Edited 4 Sep 2015 by alvis

Hello, Not quite right there. Since you have two ID231 installed consecutively : - 1st one will use 0.0>15 and 1.0>15 - 2nd one will use 2.0>15 and 3.0>15 Same rule apply for the ODs Also if you feel unsure, you can check the I/O Table to see which word it started. Example your 1st ID231 should have 00 on its I/O Table, and 2nd one should have 02 on its I/O Table. This means the first ID231 occupies address 0 and 1, while the 2nd one occupies address 2 and 3. For the CompoNet slave, if you are using Mode 0 and Unit No. 0, - Output of MD16 : 2000.0>7 - Input of MD16 : 2008.0>7

Hello.i am new in Omron Plc.I have a very easy question but for me is not. I need to add a new wire from where I can take a new signal , is a new sensor , i dont know how to assign it , don't know how to assign a new adress in cx programmer so the plc can see it ok.The omron Plc has 4 murr attachements , where i need to assign it( it is the nr X3 03 from carte D murr) ,maybe you can tell me the correct  format of adressing for this one so I can make it.thanks

You should really start a new topic. No one will be able to answer your question without knowing a lot more information.

What is the PLC model?

What is the Murr attachment? Model number? Type of connection? Protocol? Node address?

It would probably be best if you could post your PLC program and whatever network configuration file you may have.
