You can use the C200H-NC211. The CS1 can use C200H modules. I am guessing that the discrete modules (ID, OA, OD) are either 8 or 16 point modules. These will cross over without issue. The NC211 will map into different memory addresses then on the C200H cpu. Your best bet is to refer to the W339 manual. This manual covers in detail the memory mapping for Special I/O modules, both C200H and CS1. Addressing will depend on the Unit or Mach Number set on the front of the module. C200H modules had a single rotary switch, CS1 modules will have two switches (16 to zero power, and 16 to the first power). Hope this will help.

Thanks for the correction Sleepy. I do very little with AB, and was thinking about directly addressing a bit instruction with a N7 bit address. Was not thinking about using an instruction to access the bits.

With CX-Progammer V2 you will have to create a program. Newer versions have an auto-online feature that will connect and download the code.

Yes! Starting on manual page 21 (pdf page 27), it will walk you through the process. How to start a project, creating a ladder, downloading, and monitoring the program. You may also want to visit www.knowledge.omron.com. The manuals for the CQM1 will be available for downloading there. Hardware manual is W226, programming manual is W228. Do a search for those numbers and it will take you to the manual. Is the RS232 port being used on the processor? By default, it should be set up for Host Link and you should be able to connect to that port. Default communications are 9600 baud, 7 data bits, 2 stop bits and even parity.

The Data Types conversation usually becomes a real "can of worms". The data type ONLY defines how CX-Programmer will display the data on screen. The PLC always stores and works with data in HEX. Data Memory (ie: D00001) is similar to the N7 memory area in an AB PLC (however you can NOT access the bit level like AB). In the example, they are moving the analog value to a data memory address to allow further processing of the value, or to "snapshot" the value if it may be changing. You can move your analog value from channel 1 (2021) to any DXXXXX address you like. None of the zeros in the D00001 address reference unit 0. Just keep track so you do not overwrite the value somewhere else in your program. CX-Programmer will remove "leading" zeros from the address. Therefore D1 is the same as D00001. You will probably want to use "channel" data type here as well. I am sure there will be other discussion on this data type question. This is only my thoughts. Just try to remember that the data type ONLY controls the way CX-Programmer will display the value. Hope this will help.

I have not experienced this problem. What are the indicator lights on the CPU doing: Does the RUN light go out? What is the status of the Alarm/Error light, solid, blinking, off? Do you have a handheld programmer? If so, what is the error message on that unit? Any additional information would be helpful.

Can you tell us to which module you will be connecting the solenoid? Documenation is available for most modules. You will normally find it in the Operation manual for the plc you are using.

I just uploaded the User Manual for CX-Programmer V2. There is a quick start in one of the first chapters. CX-Programmer V2 User Manual at Mr. PLC.com Hope this will help.

Sorry about the incorrect information, it has been a long time since working on an NT20M. Have you tried swapping the NT600M-LK201 units? This may tell you if that unit is the problem. Since you do have one working NT, by swapping the host interface unit, if the NT that is now working gives the HOST ERROR message, you can be pretty sure the NT600M-LK201 is the problem. Just a thought.

OK, I think I understand. The HOST ERROR message would be expected based on the fact that there is no PLC connected to the NT20M. The NT is not getting a response signal, so it thinks there is a problem with the PLC. I am pretty sure that is true. With no files loaded into the NT, the unit will not know how to communicate with the PLC. The PT Control and PT Notify areas handle the communication between the two devices. I would try loading your program into the NT20M and then see what happens.

What software are you using? You may need to turn on monitoring to see element status. All of the software has this capibility, but some packages required initiating it separately. Hope this helps.

The W339 was the original CS1 op manual, and the CJ1 is basically just a physically smaller CS1. I know that statement is not 100% true, but close for this conversation. The W340 manual, which is the original CS1 programming manual comes in at over 1200 pages! That is a lot of paper! There are some CJ1 specific manuals that will help if you are using the -CPU2x controllers with the built-in I/O, W393, W394 and W395. I usually end up going back to W339 and W340 because the explanations seem to be more complete. Any other questions, please just ask.

Kcor, Hate to tell you this, but I have had more than one customer have problems trying to connect with the Belkin unit. Have had fairly good success with a unit from BAFO model #BF-810. However, it is not 100%. Omron does offer a USB to Serial unit #CS1W-CIF31 that they have tested to work with all Omron products. Hope this will help.

You're welcome! Glad I could help.

Is this existing or new hardware installation? Are the NT files new or previously tested? I am trying to understand what may be happening. The error seems to indicate that the NT20M is not communicating with the PLC. Could be bad hardware, bad cable, or incorrect setup in the NT. Any additional information you can provide would be helpful.

My first guess is that you need to change the F to #20 to designate a constant value of 200 hz. By setting "20" the plc is trying to use IO channel 20 for the pulse value. Very good possibility that IO channel 20 value is zero (0). Hope this helps.

The manual you want is the W339 manual. It covers the CS1 and CJ1 products. The manual for the analog modules is W345. They can be downloaded from www.knowledge.omron.com, or may be in the download section on this site. Be careful with the analog modules! There are two rotary switches on the front of the modules that define the "unit" or "mach" (same thing) number! Physical placement has nothing to do with the addressing of these modules. This may help answer your questions regarding the MOV instruction. The ID211 will be (CIO=core IO, but not really part of the address) 0000.00 - 0000.15. The OC201 will be (CIO) 0001.00 - 0001.07. Feel free to ask more questions. I think you will really like the Omron PLC once you get use to it! gtsuport

Your welcome. Glad I could help!

Do you have a valid screen number set in DM0000. Note that zero (0) is not a valid screen number. This will need to be set in the CQM1H.

Lets start out by turning SW1 pin 1 to ON. This should turn off automatic reset and hopefully will display the error. Maybe this will point you in a direction.

OK, so you made me set up the system to make sure I tell you correctly With CX-Programmer connected to the controller and on-line, click on IO Table and Unit Setup in the workspace on the left. When the IO Table box opens, you need to double right click on the [0000] Main Rack. If this is all blank, then click on the Options pull down and Transfer from the PLC. You should now see the SCU in the appropriate location in the rack. Click on the SCU, then right click to open a menu box. Move cursor to Start Special Application, then choose Start with Settings Inherited. You should get a box to choose CX-Integrator or CX-Protocol. Choose CX-Protocol and CX-Protocol should start, and you should be good to go.. Good Luck! Hope this will help.

I think it will depend on the version of software you are using. With CX-One, I believe you can access the SCU through the IO Table and start CX-Protocol with settings inherited (knows to go through existing connection). I think this is correct. If using previous versions, pretty sure you will have to do as you described. Good Luck!

Copying post from PLCs.net I do not know the capability of using a web browser into the ethernet port. I know you can set up the ethernet module using a browser, but I don't think you can directly monitor I/O. This is an interesting topic, anybody able to offer some input? Thanks, gtsuport
