Hello, I have a PanelView C400, the moment it powers up it starts the runtime without a provision to exit or to go to configuration. How can I access the HMI so that I upload the HMI application to my PC? Also, Can you assist me with USB RNDIS driver for Allen Bradley PanelView XP. I am using FactoryTalk View 5.0 ofr communication with RSLinx Entreprise. Regards,

Hello, I have a micrologix 1200 which is connected to a PanelView C400, the PLC had a Fault which I cleared and now it is OK and running, but the HMI that is connected to the PLC is now displaying Data Access Error for Alias /*S:0 Param2*/,Controller /*S:0 Param3*/, Address is /*S:0 Param4*/, Communication Flag is /*S:0 Param1*/ Communication cable is connected. Please Help. It's urgent. Regards,

Dear all, I have a red flashing fault on my Micrologix 1200. Also, as soon as I connect it to PanelView C400, the inputs of the PLC get de-energized (but PLC is still on with red flahing fault). How, can we go about it? Regards,

Hello, It is solved now, just a power issue. Thanks...

Hello,  I just installed RSlogix 500 and RSlinks on Windows 7 32 bit. in other similar machines it worked fine. But on this one it is bringing the issue of port may be in use for all of the port up to 31. Therefore I cannot configure the drivers. Regards,

Hello,  I am receiving this error Fault code=0001h after communicating with RS232. Bear in mind I also have a Battery fault. My battery has 0 volts as of right now. Is that related to Fault code=0001h ?  Regards,

Hi, thanks for replying. Yeah I remember seeing NVRAM error. No I haven't tried clearing. What about battery fault? Could i still use the PLC with a dead battery? Regards,

Hello, Would you like to help connect a  a FX-16MR to HMI? Regards,

Yes the PLC is that one. I have many different Siemens HMIs.

Hello, I have received one CP1L PLC CPU for troubleshooting. It is password protected. Is there any way to solve it and backup the program? if no, is there any way to reset everything.?Regards,

Hello, A power surge occurred in a plant and the ERR led on the  CMP1 CPU30  is now ON. If you have noticed I have a post referred to as Communication failed for CMP1 CPU30. Now that I am waiting for a new communication cable to be shipped, I would like to know what remedy is possible for this issue. Best Regards,  

Hi Bob, How could know if the PLC is dead after communicating?  Regards,

Ok. Thanks a lot man.

Hello, I am trying to connect an OMRON CMP1-30CDR-A-V1 to my PC. I used a CQM1-CIF02 cable which I connected to RS232-USB converter and then to my laptop. Is this the right way to do it? I have seen on the OMRON website the attached diagram. Should we use that device or an RS232-USB converter will be enough? Also. I tired to use a PC with RS232 port directly but it also failed. Regards,  

Thanks for all your support. Now that I have decided to purchase a new cable. Which cable will assure communication between a PC and  an OMRON CMP1-30CDR-A-V1 . Regards,

Hello, Can you guys help me sort out what's wrong with this? info: I have never connected this PLC to a PC. I got it like that. I just powered it on and as you can see the led. few things are faulty. Also, I don't have batteries and MMC but it's okay. Even with a different CPU and CP it's the same thing. regards,

Thanks, are you sure that's the problem? Without a battery and MMC it's okay for an  S7-400 CPU since it has got internal RAM.

thanks  all for your support. It really is urgent for me that why I'm trying to modify the above cable. shipping will take time.

Thanks, Can you help me modifying the cable I have so that it will work. 

Thanks, Do you mean that each time I use the peripheral port I need some kind of box to covert the signals? which one will suit my  CMP1-30CDR-A-V1  PLC? Regards,

No interface box. But you re a that we use   CPM1-CIF01 . is it necessary to use that? this is what i use.

Yes, the serial to USB adapter works fine because I succeeded to communicate with two other Omron PLCs with different cable ( but same adapter). Now, Could it be the cable shown above that might be problematic?

Yes, there is a driver for rs-usb converter. but what do you mean by pin configuration?
