  1. So, here is a knife to the Beijers back- a simple and inexpensive programming cable for Mitsubishi FX series, to be used instead of SC-09. The cable is successfully used with FX0N, FX1N, FX1S, FX2N. EDIT: According to repeated complains this cable may not work with FX0, FX0S. The connectors on the diagram are 8-pin mini-DIN male on the PLC side and 9-pin sub-D female on the PC side. Take measures in order for the PLC pin 5 (+5V) not to be shorted with any other one in order to prevent the PLC or PC port damage. For AC powered PLC, the requirement to avoid phase conflict by powering PC from the same AC phase remains in power, exactly as for the SC-09 cable. The difference is that in a case of phase conflict at least cable is not damaged now.
  2. I am trying the Fins Color Coded Messaging Tool While successful with CJ2M, never could make it work with CP1W-ETN61 on CP1H. What should be the network, node and unit numbers in such case? The unit number is the most unclear. 
  3. ZCP Instruction

    Two inline comparisons in series give the same result, but execute 20 times faster (in CP1H).
  4. Conversion

    DBLL converts a 32-bit signed binary value to double-precision (64-bit) floating-point data. Not UDINT.
  5. Bits on Contactor

    The CP series does not support addressing individual bits of data registers. The CJ series does, but only for D registers, not C or T present values. If you need to monitor a bit in the counter present value, copy the value to W or CIO word, and use the bit from there.
  6. Why (U) an OTE?

    The OP never said the OTUs are interleaving with non-OTU coils of the same bit, but all are after the initial and only OTE. Therefore, not '"the last unlatch wins", but the bit is unlatched locally wherever required, and supposedly used after the last OTU. I often (though not extensively) use such technique, which I call a "collector bit". The example may be resetting a machine error bit with OTU or always Off OTE in the beginning of the program, and setting it locally anywhere it is decided. At the end of the program, the bit is used for beacon light control. Any technique has advantages and disadvantages. The advantage of this one is seamless adding or removal of standard pieces of code (the addresses of the collectors have to be standardized first, of course).
  7. Cj2m cpu33 No comms after downloading

    Double-click the "IO table and unit setup" in the project tree and transfer the IO table from the PLC. There is such icon there.
  8. Cj2m cpu33 No comms after downloading

    See this thread. Probably, it will help you at least with the USB communication.
  9. Cj2m cpu33 No comms after downloading

    The error HE is tag datalink communication timeout, and IP 07 (not 1P)  is the last octet of the erroneous node IP address. Did you download only the program, or data memory as well? The latter might change the communication settings, as well as "Set defaults" in the Ethernet port configuration.
  10. Minimizing OR function

    The complete instruction would be: <> K4M801 H0
  11. Omron Servo Encoder

    Because the PRV2 works only with HSC0. The PRV may be used to measure the speed programmatically, with certain limitations in resolution and update period.
  12. Sysmac Studio 1.22

    All posters: Mentioning the OS would make big sense in such cases!
  13. Half Screen when app is opened.

    Tried it. No result.
  14. Half Screen when app is opened.

    Same problem, but no such menu option in the v9.45. No matter the Information Window being On or Off.
  15. After changing the computer name, I cannot configure the RSLinx Enterprise communication in Factory Talk View ME Studio projects. It says no such computer in the Factory Talk directory. How can I fix this?
  16. What is the Use of Number data type for CJ2 Omron PLC?

    In other words, a Number type data is a named constant.
  17. From my experience, the mentioned error will appear if there is another session of the CX-Programmer running, with transfer-related dialog box active. Even if the transfer (upload or download) is already finished, and the dialog box is only waiting for OK. Or, when the CX server stops working. In such case, the CX-Programmer restart helps.
  18. I want to install and run the Rockwell software on new Win10 PC in the Oracle Virtualbox VM. However, my Factory Talk activations are tied to the hard disk serial number. Tried to change the VM hard disk serial, with couple utilities, but no success. Any suggestions?
  19. Motor Offset or Controller Offset?

    CompactLogix with integrated motion. Hyperphase absolute encoders. There are the Motor Offset and Controller Offset options in the Axis properties/Motor feedback. The manual says "in the most cases it would be the controller offset", however does not explain when and why. Could anybody explain the difference and the preferences.
  20. Motor Offset or Controller Offset?

    So many unnecessary technical details, and still absolutely unclear when and why use the controller offset or the motor offset.
  21. CP1H-XA "Failed to connect to the PLC" with USB

    500ms?! What may be such an application? I've tried this on a live CP1H, and it indeed falls into communication error. But, after changing the USB Respone Timeout from the default 2s to 20s, I was able to communicate and revert everything back. However, the responses were SLOW. Expect almost a minute delay between every mouse click and its result.
  22. CP1H-XA "Failed to connect to the PLC" with USB

    What did you change the constant cycle time to? And can you afford wiping off the entire controller content?
  23. CP1H-XA "Failed to connect to the PLC" with USB

    I have seen couple CP units with the USB port damaged by 24V due to wrong wiring. The incident may be instantaneous; the wrong wiring may not be there anymore. I used a communication adapter board in such case as an alternative port, e.g. CP1W-ETN61. 
  24. CP1H-XA "Failed to connect to the PLC" with USB

    This confirms the PC port is OK, but not the PLC's.
  25. CP1H-XA "Failed to connect to the PLC" with USB

    How do you know that? Meaning the PLC port.
