IO_Rack

Yes, you can make your own. This is a simple RS232C connection. The CQM1-CPU21 has a built in serial port so you can use this cable. Choose SYSMAC WAY for your Network Type, default Omron settings are 9600, 7, E, 2. Alternatively, you can purchase the CQM1-CIF02 Omron cable. This cable has the electronics inside for protocol conversion and would utilize the Peripheral Port.

To the best of my knowledge... No. After all, the LK201 is the interface used for programming the PLC to begin with. To elaborate on your question... Your PLC possibly has a 'Registered I/O Table'. I guessing this because of the ALARM you got when you removed the modules. So the PLC possibly knows where it is at on the rack. But... The pre-Alpha series PLCs did not require a registered I/O table except for some 'Special I/O'. I could be wrong about the special I/O... maybe it was just to generate an ALARM when something has changed. I'll bet Jay A. knows! Anyway... my testing has proved that with a registered I/O table or not, memory module or not, I can plug the LK201 in any slot on my CPU BASE UNIT rack and connect with CX Programmer. The only other thing I can think of is, if your PLC were initiating communications to your HMI PC. In this case it would have to address the correct Host Link unit. I don't believe the CPU21 is even capable of this. The string you posted from Hyperterminal shows the PC asking the PLC for information. This is very common as Host Link is a Command > Response protocol. In either of the cases above, I believe the original programmer has made provisions for this in the ladder program. The fact the you swapped ROM modules and you appear to have a registered I/O table. It is probably writing to DM memory on power up. This is the memory that sthompson was referring to. I believe if you get a working unit and match the switch settings then you'll be OK. Good luck.

In my experience these units are very tough. Rarely, do I see them go bad. Nonetheless, your testing has shown us they will not respond. Do you know what happened prior to the PLC going bad? I do not wish to beat a dead Host Link unit but just for good measure, you should try each Host Link unit in the CPU Base Unit rack again, attempting to communicate with your monitoring system and with CX Programmer. Take note of the status of the XMT and ERROR lights. If either of them come ON then that is an indication it is receiving something. The manual does suggest the indicator circuit for the RCV light could be faulty. The LK201 is obsolete and is the only option for communication with these PLCs, other than the 3G2A6-LK201, in which case you'll also need the BP001 due to your OC224 module in the way. You may have a difficult time finding one. You'll probably have to search the web. There are some 'after market' repair centers and Ebay. Alternatively, you could upgrade. The physical upgrade would be very easy as you could reuse all your modules and you can get them with a Host Link port built into the PLC. The down side is, the Host Link commands may (or may not) need to be tweaked and you still need the program from your existing unit. Contact your local distributor for more information.

I'm sitting here with FactoryTalk View Studio Ver. 6.1 open in front of me. I do not have a PanelView Plus to test but I'll take an educated guess. Right click on the Display that contains this object. Choose "Display Settings..." Click on the "Behavior" tab. Click the check box that says, "Disable Highlight When Object has Focus". Let us know if that works.

I have created a similar situation with my test rig. (C200H CPU01). I created an I/O table then swapped the modules around. I get the flashing ALARM light as well. I am still able to connect with the LK201 even though it is in a different slot. Only try this if you are comfortable doing it. Use a 9 Volt battery and connect the minus (-) side to pin 7 of the RS232C port of the LK201. Take the plus (+) side of the battery and briefly touch it to pin 3 of the RS232C port of the LK201. The RCV light should come ON. I did this with mine. I did this using small pieces of wire and sticking them inside the pins. - The PLC must be powered ON and the RUN light on the LK201 must be ON. - Double check your connections before touching the 9 Volts. I don't know what will happen if you select the wrong pins. - If the RCV light does NOT come ON then I would have to say that the LK201 unit is bad. Try both units. I find it unlikely that both of them are bad. - If the RCV light does come ON then you either have a bad cable, connector or connector pin.... or you are not sending data.

Jay and Bob, Thanks for the feedback! I'm smacking myself in the forehead right now because I'm well aware of the interference issue and the use of the PRO CON BASE units (BP001 and BP002). I just didn't relate the issue when reading the manual.

I did notice that both of his modules are in the restricted slots. After revisiting this I found conflicting information in the manuals. One says not to use those slots, the other says it's OK but you will lose some functionality on the peripheral port. I don't know. I did try mine on the slot next to the PLC (7ch) and it worked OK. In any case, look here: I would continue the troubleshooting with CX Programmer although you said you get the information from your HMI to Hyperterminal. Remove all the modules from the rack and try the Host Link in another slot. Maybe the backplane is bad. The PLC configuration does not matter. All the configuration is done with the LK201 switches. Do you have lights on the other I/O modules? Maybe the PLC power supply is bad. Check that you have 24 VDC at the 24VDC OUTPUT terminals. Check the RUN OUTPUT terminals when the PLC RUN light is on. You'll need to tell us in more detail what you have done.

Have a look at the manual supplied. Look at the Pulse Output section in the manual. Pulse Output is acquired by special instructions. NOT programmed as a coil.

One of the other old school guys will have to answer this one. What is the part number of your back plane? The ones I'm testing with right now are C200H-LK201 and C200H-BC081. Neither of them are V1's. This may or may not be an issue if they are mismatched... I don't know. I would still think you should see the RCV light.

Yes, as long as it is NOT in the first two slots immediately to the left of the CPU.

The RCV light should blink every time your PC sends that string even if the PLC is not responding. If it is not blinking then you have a bad connection. You should verify the cable. The string, " @00RR100002043*" appears to be missing a character. This is the PC attempting to read IR memory from the PLC.

I did an internet search for your PLC. Here is the C200H CPU21 Installation Guide. It is a pre-Alpha series. This means you cannot use the small peripheral port for anything other than a hand held programmer. The long port at the bottom is for a 3G2A6-LK201. This is basically the same as the rack mounted unit you have. The rack mounted LK201 should NOT be mounted in either of the two slots to the left of the CPU or on a remote rack.

The manual in the link I posted above describes these functions. SW1 = 0 and SW2 = 0 This means the Host Link Unit Number is 00. This is a node address. If this is a 1 to 1 connection between the PC and the PLC then this is probably correct but not guaranteed. SW3 = 5 Baud rate is set at 9,600bps. SW4 = 2 More serial parameters, ASCII 7 bit, 2 stop bits. This is common Omron serial settings. Also the command level is set for a custom application for full read and write. Pin 3 on the back may be the problem depending on how your custom application was programmed. It determines if addressing is required in the event of a muli-link system. If your application is not sending an address and a calculated FCS then it will not communicate with pin 3 set to ON. Try turning if OFF. For communications with CX Programmer, you should be able to use the same cable that is currently connected to you custom application. It's on page 9 in the manual. As far as using the peripheral port... I'm not sure. If it were a C200HS or HX, I was say yes. I'm not familiar with the C200H CPU21. Be careful what you plug into it. I have blown internal circuit board fuses on some of the older C200H's by trying to use that port. On the older ones, it was only intended for the hand held programmer.

Have you tried to re-install CX Programmer? You should perform Omron's Auto Update and at least get the lastest CX Server. The CX Server installation actually contains the necessary USB drivers. I've never had to go searching the web for Omron's anything, unless it was obsolete.

The DIP switches are on the Host Link Unit. C Series Host Link Units

When you connect the PLC via USB the first time, it will prompt you for the driver. With CX Programmer properly installed it should reside here: C:\Program Files\OMRON\CX-Server\USB.

I'm not sure about the X32 vs. X64 issue. I have had the problem you describe above. I installed RSLogix500 Professional from our ToolKit then tried to activate it using our customer's dongle which was licensed for RSLogix500 Standard. Have a look at this if you have ToolKit access. 67676 - RSLogix 5, 500, 5000 Not Seeing Activations

You can verify your communications via the PanelView's configuration screen. My practice is... once I establish communications with the PanelView, uncheck the "Replace Communications" check box when performing additional downloads.

You didn't mention this so I'll ask.... Does the IP address you assigned via BOOTP match the IP address in the RSLogix5000 project? You should get a warning dialog before the download if they do not.

Here is the manual: CPM1/CPM1A/CPM2A/CPM2C/SRM1(-V2) PROGRAMMING MANUAL The CPM2 will only do 20kHz Input and 10kHz Output. Have a look at the specifications on the CP1L.

The "W" are indeed cryptic. I don't believe you need to concern yourself with those numbers. The CVM* versus the C500* numbers are a bit confusing. This is probably because the CVM series was designed to replace the old C500 series processors while still utilizing the C500 I/O. There are some Omron guys here to confirm my antiquated memory. Even the CVM may be obsolete at this point so yes, the manuals are difficult to find. You have come to the right place to find them.

I'm going to attempt to transfer a runtime application from one PC to another. Let's say, the customer has a working dongle but does NOT have the original CD with the license key. Will the dongle override this or otherwise take of it? If not, what are my options without the original license key?

OK, so I was being a bit facetious with this remark. As it turns out, the wonderful maintenance guy at this facility had everything! I did get some wrong information about the version. I verified the current running version was 1.24. He had the install disk for CX Supervisor 1.2, the upgrade disk to version 1.24, the touch screen software and development license key. I was truly amazed. Furthermore, he has backups for all the PLC programs, all the communication card programs, and network configuration files. Very rare in my experience. The new PC did have a parallel port. I installed the dongle then ran the dongle installer as PdL suggested. The entire installation and setup was easy. They have several systems at their facility, I would still be interested in others experiences with a PCI or USB parallel port for future reference. Thanks.

Thank you for the info. You say Ver 1.1 came with a DB25 dongle. This is good information as this may be a problem as well. I haven't seen the PC yet but most are not equipped with a parallel port these days. Have you (or anyone else) attempted to utilize the dongle with a PCI parallel port card? How about a USB to parallel port converter? That last resort would be to upgrade. I'm assuming that I'll need the development files to create a new runtime. Is this correct? I'll find out more after my site visit today. Maybe they'll have all the relevant material neatly tucked away in a filing cabinet somewhere.
