  1. Error on connecting to plc

    Hello, First thing, I'm new over here, so probably I don't know everything, and second thing, sorry if my English is worse than I think :( Now, what's the problem: I have CQM1H - CPU51 plc, and until yesterday it worked fine. But when I tried to look into its communication protocols via cx-protocol, something went wrong as I suppose. Since that, I'm unable to connect to plc - usually message is "Failed to connect, check following:..." or sometimes "No response from plc" (which probably means that there is connection if pc can send data to plc?). LED "comm" on plc is not blinking when I'm trying to connect, so it looks... not good for me. I tried using rs232 port in cpu unit, on serial communications board, only peripheral left, because I don't have matching cable. Anybody knows how to make communication work again?

  3. Download program to Memory card

    During downloading the program, in order to transfer it should be in a program mode. Now the CPU has no battery so I'm forcing AR14000 to download the program in the EEPROM. but I'm getting a Fatal error Memory Fail. Is my procedure correct or is there another way to download the program into the EEPROM? Hardware details: 1. OMRON CPU: CQM1H-CPU51 2. OMRON MEMORY: CQM1-ME08K
  4. Program lost after power cycle

    Anyone can tell how to retain the edited(downloaded) program into the omron PLC? it's my first interact for this brand but when I try to downoad my program into the cpu it works as long as it is power on, but when we turn off the power for the whole machine and power up, the program that I downloaded previously is removed. Is there a facility like a "Copy RAM to ROM" in siemens here in omron software? how can I download the program without losing it? Thanks!!!
  5. CONVERT FROM CQM1H TO CJ2M

    Hi there, I would like to ask you regarding the conversion PLC. Usually, it is not a surprise for us to get the errors occurring for the PLC conversion especially if both PLCs are not in the same compatible programming software. What I mean, currently, we have a lot of older version of PLC such as C20, C40H, C60H etc and these version needed to be converted to the newer version. However, lately we have problem converting the CQM1H to CJ2M, whereas both PLCs using the same programming software, CX-ONE software (ver 9.6). Most of the errors are displayed like this: ERROR: Step at rung 161 (6, 1) - SBN not defined - 4 There are 4 errors are listed referring to the same type of errors, that is the SBN not defined.  Is there anyone here ever experienced this? And why is it these two PLCs also got problem for converting? Thanks all.

  7. I'm having trouble communicating with my PLC. I have an CQM1H-CPU11, I'm using a USB-CN226 cable. I installed the driver that came with the cable. If I try to go online, it pops up "Failed to connect to the PLC." My dip switches are currently in the the positions of 1 off, 2 off, 3 on, 4 off, 5 off, 6 off, 7 on, 8 off.
