Hi, In one of my application, I am planning to implement Cat3 safety circuit with one E.stop controller and three E.stop buttons in series (dual channel). This sound simple but two of the buttons are placed 3500ft (1.1km) away. For 24 VDC system at 18AWG it should not be a problem. But as far as I know the controller would be checking the E.stop button wiring by sending pulses (I think at 5V but not sure). So would the length be too much and false tripping may result? If anybody has past experience with similar implementation please share. I am planning to use Allen-Bradley E.stop controller but any other brand that can handle this length is OK.

Hi All, I installed CX-One V1.1 few months back. Everything was working well till I wanted to connect to NS-12 and download a project. Whenever I tried "transfer to PT" it gave a message "unable to process CX-Server..." I contected Omron tech-support and I was advised to uninstall CX-One, CX-server and CX-server management tools. At the end of uninstall process (during which it gave various confusing messages like installing files...registering new installs etc..etc.., I wasn't installing believe me.) it said "ROLLING BACK ACTION" .. and the un install wasn't finished. Now this happened cuple of times, I tried to uninstall cx-server and server management tools. That happened without a fuss. I was given CX-server cleaner software by omron, used that and cleaned up everything of cx-server. Now the real problem started, I can not uninstall the CX-one. Re-install is also not working. I cleaned up registry manually but it doesn't delete couple of Fins gateway components like AmFinsRemote & AmShmem. I tried to install again and again but it's not working. Any solutions?

OK, I got the unlock from someone on who guessed it. All good now.

Hello All, I have a guardlogix processor that I just safety locked with a known password. When I tried to unlock, that password didn't work. Upon reading a bit I realized that the lock and unlock passwords are separate. I never set the unlock password but blank doesn't work. Could it be a leftover due to program copy paste or is there a way to find/reset this unlock password.    

TWControls, I'm not trying to hack a machine. I am commissioning one and set the Lock  password. Thought the same would work for unlock unfortunately it didn't. This is the first time I'm working with AB safety and so need some help.  Here is a question, if you copy an old program, modify it for another processor/cell, would the unlock password stay as the old program? Again guys, I'm not trying to hack or create trouble, its a genuine question and I need some guidance.      

I agree with Davkul. Disable all the network adapters other then one used for Bootp. 

Hello, I am using R88D-KN08H-ML2 servo drive with R88M-K75030T-S motor. PLC is CJ2M-CPU35, with NCF71 position control unit. There are total of 6 axis and the one in question with above combination is giving me trouble, rest 5 work OK. I get Overload trip error even at 200% of torque. The motor doesn't move at all. After disconnecting motor power cable, it is possible to move the assembly by hand so nothing sems to be jammed or binding. Tried Auto-Tune, ended with successful completion (at least no errors etc). But scenario didn't change. Motor doesn't have brake, as per model number as well as physically no brake cable on motor. Since all other axes are moving, with similar setting, not sure what is going on here! Any parameters I can change? Any other way to check?

Update: So I removed th motor from assembly, it was free to move. Still same overload error!! Removed both power and resolver cables, pins were okay too. Put it back (electrician), tightened it. Wallah.... Probably a loose connection on power cord? I noticed one screw out of 4 missing on power connector.

Hello everybody, I have CJ2M-CPU35 connected to couple of devices over ethernet IP. I would like to know which bits in CIO area (25 words for built-in E.Net port starting at 1500) gives me the status of Individual nodes (i.e. connected or not connected) Tried to go through W465 but there is a lot of information and I'm getting confused with built-in port, additional E.net IP units, Fins TCP, Fins UDP etc.

OK Gentlemen, I had another chance to connect the same PLC with a different device on Ethernet IP. And it works! The node address this time is 15 and I see that last bit on 1516 and 1520 is ON. Thank you so much. PS : Does the PLC have to be node 0 (curretly it is)? What is the significance of that question?

Thanks for the reply Sergey and Pdl. Sorry, Couldn't check the messages for past few days. And now I don't have temp setup However, I would like to understand following. Since this is the first time I'm doing Ethernet IP on Omron, I would reapply appreciate if you can throw some light on few basic question. -1516-1523 should indicate registered nodes. If zeros, these nodes are not registered for communication in the unit. > I saw all zeros. How do I register a node? I thought it is done by network configuration download to PLC. What else needs to be done? -Is the unit the connection originator? Is the unit #0? > I am not sure if I understand the question correctly. The PLC is set as originator & "Exclusive Owner". I thought the node address is unit # which for CPU is 10 and RFID is 59 (i.e. 192.168.0.10 and 192.168.0.59). Where can I see/set the unit#? -Was it restarted after the last download? > No, I didn't. is this expected after every network configuration download? -Is the mentioned node address 59 decimal or hex? If hex, it is out of the 4-word range. > I think it is decimal. This is set by clicking on device in network configuration and pressing "Change Nore address". This give a pop-up where IP address is set, i.e. 192.168.0.59!

Anyone idea?

So, finally I have a temp setup on my desk with CJ2H CPU64-EIP (192.168.0.10) connected with an IFM RFID reader DTE102 (192.168.0.59) on EthernetIP. I have done the network configuration and I see that the communication is working. The LED's are flickering with right colors and I do see some bits back and forth. I used the logic mentioned above, but don't really see any change in any registers 1516-1523. All bits remain 0. I actually changed the node address to 59(from 79) so thatit falls within 0-63 node area but nada.. Some general fauls are visible in CIO 1510-1512 bytes, but I am interested in node specific error. Any further suggestion?

Oh, One more thing, this is for node address 0-63, which is the last octate of the IP address. For 64-255 node addresses, allocated CIO area has to be set to user settings. See section 4-4 of W465 for more details.

Thank you Propeller head! I was confused with the terminology in W465 like Unit status, Communication Status, Connection status etc. which are also part of 25 word block assigned to internal EIP port. I wanted to add some screenshots from W465 explaining the bit status in Omron Lingo but it does not allow me to add screenshots. Anyway, the code is pretty straight forward. The exclusive OR makes sure that when the node is registered and connetion status is low, the O/P bit turns on.

Hello everybody! I have a question about the CIO are usage. The software manual W473 says thsi area CIO 3800 to CIO 6143 can be used in program (only). So I think I can use any of these bits/words in the program. However, I am trying to standardise some area for Axis Input and outputs for mutpliple stations and even for future projects. Hence the question to the masters, is there any restriction in using this area freely in the program?

Michael, Thanks for quick reply. I did see this recommendation in software manual as well. Is there a reason though? My question on this forum actually is to understand if there is any technical reason! Total for In and out words from 16 axes is 16 x 25 x 2 = 800, the W area can only give 522! CIO area also gives some flexibility like stating Out at x000 and IN at X500 etc. which can remain unchanged for any number of axes. W on the other hand can be used for HMI and some other specific program use. Any thoughts?

Hello, I would be adding two 32bit DI modules in existing CC-link network in one of my projects (on Q06HCPU). I am trying to figure out the X & Y address areas in CPU for these additional stations. Currently the network has 27 modules, 0-33 stations. I read the CC-link master user's manual (SH_NA_080394-M) but few things are not clear yet. What is the purpose of Srart XY or Start I/O No.in PLC parameter (0080 for the CC-link master)? Is it to identify and fix the location of the CC-link master? In other words, nothing to do with device memory for Remote Input (RX) and outputs (RY)?In CC-Link network parameters I have following setting - RX : X1000, RY : Y1000, RWr : D4000, RWw : D4200. X & Y defines device memory in CPU, 32 bits per station for the Digital IO (for 16 bit output first 16 bits are used, next 16 bits are unusable, correct?) but not sure what is the use of RWr and RWw. Also, there are 4 ch. Analog inputs that takes one station and 8 Ch. Thermocouple modules that take 4 stations.With above information how would I know where my digital IO addressing should start for additional stations 34 & 35?I have tried to glance through Q-Cpu programming manual and few others but its not clear to me. And as usual I am running out of time. I would appreciate any hints, suggestion of documents and answers of my questions. Thanks B

I bought the 1747-UIC for $404.32 CAD. Not sure when I will encounter another DH485 device!

Hello, I have an old color PV 600 that I want to use in one of the projects. It is a DH 485 version. The PLC would be Compactlogix 1769-L32E. There are few questions arising out of this odd combination. Assuming I set the Ch0 on processor to DH 485, the PV would talk with CPU. I have tested this successfully with an old SLC 5/05 kicking around. Has anybody already created a pasthrough from E.Net/IP to DH 485 to program the PV? I have been trying to achieve the passthrough on 5/05 but no success yet. May be some firmware of software version mismatch. I have read many articles on A-B tech support and tried many times but no results. L32E is arriving in 7-10 days. Does the DH485 work with USB to Serial converters (DF1 works like charm, no issues)? I could program the PV only with 2706-NC13 cable directly connected to an old laptop with DB9 port but new laptops don't have DB9. Any other option?How does the tag based addressing on Logix5000 work with B3 and N7s of old world that is needed in PV?Any example of using 1761-NET-ENI or something similar? I will share my findings over time. Would appreciate every bit of information I can gather here.

Thanks Ken for detailed reply. Much appreciated. I have 1747-UIC quote, pretty pricey for a converter! About the tag mapping, can you suggest me a document? Would like to read about all different data types. Ganie : Have you used 1761-NET-AIC for download as well as communication to Logix processor? Does it create passthrough for download to PV through CPU?

Ken, I guess the problem was not with the type of virtual machine but how the FactoryTalk security handles computers and users. If I kept the Host computer name as before, I could have avoided this situation. It would be a good experiment on your side to install the vhd on a different host computer (different name at least) and see what happens, you may share the experience. On a side note, I am fairly used to the Windows Virtual PC and it has worked for me so far (have Siemens, Omron, Mitsubishi, VB, Rockwell and few more working well on my Windows 7 SP1 Pro). Also any other machine would need a licensed XP where as windows creates the XP mode. And yes, I did explain everything to RA Tech support, hope they would add it to Knowledge base soon.

Hello All, Just wanted to share my experience and be helpful to fellow programmers (Its been long since I posted anything...) I was running Logix5K on Windows Virtual PC (XP SP3)...than my host computer HDD crashed Fortunately had copies of vhd and I was up and running Rockwell machine fairly quickly. The Factory Talk View Studio worked without complain but while opening Logix5K, it asked "Log on to FactoryTalk". So I tried all Username & passwords, nothing worked. I looked up KB article "468494 - RSLogix 5000 V20 software promptsLog On to FactoryTalk when started". By the looks of it, this should have given enough clues to solved my issue but it didn't. The log in fail message said "There is no account for the host machine in the network directory", but there is no way to add it, since you can't log in. Why the software on virtual machine should look for a host machine in network directory is difficult to digest! I just want to use local machine for all my applications, no hi-fi security settings etc.... So my friends, only solution is to reset the factory talk services platform (credits to Rockwell Tech support). To do that, connect the Rockwell installation Hard disk (Toolkit owners have this), go to add/remove program on virtual machine, select "FactoryTalk Services Platform...", press change button, than select "repair". Once the installation is done, the host machine name magically appears in network directory and all previously used host and Virtual machine names are also there. Thats it..

OK, so I have this CP5512 I used to configure and download to Profibus nodes with my old laptop. My new laptop does not have PCMCIA slot, so question 1) is there any proven USB adapter that worked with CP5512? I still have the old laptop but the Siemens software are on a virtual machine (much cleaner and safer option I learn over my many years of struggles with various make of software). so question 2) IS there a way to access the PC card from Virtual machine? So far I get "can't do" response but I want a confirmation from my own intellectual community before giving up that option. I really want to avoid loading all necessary software on host and then transfer of licences etc..

An Update.. 6ES7317-2FK14-0AB0 is the latest 317F CPU. It can only go down to FW3.1 which is available on Siemens website. Earlier version of same CPU was 6ES7317-2FK13-0AB0, which could have FW version 2.5.1 but that product is at the end of life cycle. Cancelled in Nov 2010. So I'm Ok with my first option.
