  1. OMRON CJ2M-AD08V1 - AD data fluctuation

    Hi Dan,  Thanks for the reply. I will try as u said.
  2. OMRON CJ2M-AD08V1 - AD data fluctuation

    Hi Dan,  Thanks for the reply. Yes, Values in open circuit fluctuates as the previous video. 0v is acceptable SPDT as show in the pic? 
  3. OMRON CJ2M-AD08V1 - AD data fluctuation

    hi Dan,  1) those are button switches in the control console.The reason added a switch to prevent someone accidently using potentiometer.  2) these are voltage signals. 3) Pure voltage from PSU to the ADunit via push button and potentiometer  4) Currently i don't have have any screens. Just copied from the manual for future use.   but fluctuation reduced after i connected A5 & B5 to 0V. 5) the values should be &0-4000 UINT. high count is only on open circuit condition. The values are accurate and stable at closed circuit.

    okay . thanks alot  
  5. HI,  I am re-posting this thread as i did'nt  manage to solve. The AD conversion values are fluctuating during open circuit (refer to video). And values remains stable once it is powered.My 8 AD channels are sharing  power supply. Refer to pic.   Appreciate all  help and suggestions.   thanks 15faad186bf0b0124a0db59248b78c34.mp4
  6. OMRON CJ2M-CPU13 - SCU32- Communication

    HI,  I still didnt manage to get it done.  The values are fluctuating ( like 6555**, FFF** etc) during open circuit and potentiometer is low resistance. And values remains 0 during open circuit and potentiometer at high resistance(no fluctuation).   My 8 AD channels are sharing  power suppply. DO i need connect anything to AG terminals. Appreciate all  help and suggestions.   thanks    
  7. OMRON CJ2M-CPU13 - SCU32- Communication

    Hi,  Thanks a lot for the suggestions. 1)For the ADs i used IO table to setup changed CH1-8 to enable and 0-10V in (All  voltage/current hardware dip switch set to  off). I am not sure whether any open circuit static V or anything like that. ( wiring attached, Blue color cable to 0V. A5 & B5 are NC). 2) For the data writing issue, i checked the CPU1 side D100, very stable and no issue.  But  at CPU2 side, i can see the data fluctuation in D2000 . Seems like Before transferring is ok and d2000 is overwriting only after receiving. scu32_TEST.cxp  
  8. OMRON CJ2M-CPU13 - SCU32- Communication

    Hi,  I manged to establish the communication after adding a end code. Is there any problem if i use 'FF' as start code and FE as end code.? I can receive the data now.  but i have 2 issue now. After uploading program, need to power cycle the receiving SCU32 , then only 1534.06 works. Is it common or i miss something like restart bits? ( program remains same as previous posts) i am transmitting D100-108(D100 is DI, D101-d108 are AD) data to receiver's D2000-2008 memory (18bytes).  My analogue input  in TX side fluctuates from 0000 to 655XX if not powered, so the Received data in d2001 -d2008 follow that fluctuations. During this time some bits in  d2000  also activating, seems somthing is overriding my data.  is there any chance that d2001 data can override d2000? THANKS A LOT  T J SHARON

    thanks  a lot for the reply.  To have a better understanding, i am adding up some more info below. Surface rack - CPU1 ( CJ2M CPU13) + SCU32 (unit0 port1, 4 wire & terminating resistance on)  MCP RACK - CPU2 - CPU2 ( CJ2M CPU13) + SCU32 (unit1 port1,4 wire & terminating resistance on) Connection via 2m twister pair Wiring, setting and program as shown  in pic.   SURFACE-NewProgram1-TXDU.pdf scu32_TEST.cxp
  10. OMRON CJ2M-CPU13 - SCU32- Communication

    hi ,  i have some issue, I tried communication between two SCU32s. But the RXDU is not updating constantly. I have used the below ladder diagram. Is it correct? ( the note says NO of  A202.03  AND NC of n+9 .06, but ladder is different?) No i am confused. Also what is logical port  ( "3"in the control word#31120001 ) and what is the purpose.?

  12. OMRON CJ2M-CPU13 - SCU32- Communication

    HI ,  I am doing on the memory adresss allocation now and i would to check whether the Wxx.xx memory can be transferred from PLC to PLC. Or should i move to D and CIO memory?     thanks a  lot.

    Thanks a lot micheal, Does"no protocol' work with 1000m cable? Do you have any sample code or video?   thanks a  lot.
