  1. Level Calculation using 2 transmitters

    https://blog.wika.us/products/level-products/how-differential-pressure-transmitters-measure-level/#:~:text=A%20differential%20pressure%20transmitter%20calculates,lids%20and%20bottoms%2C%20etc.)
  2. Series Six PLC Expanded I/O addressing

    The expanded I/O addressing is mapped to R memory as shown on the third page of the pdf. It was a way to use register (16-bit) memory for discrete instructions since the Series Six instruction set did not permit anything like R123.00 to indicate the least significant bit of word R123. In programs that use the feature, you had to be careful not to use the R addresses corresponding to the expanded I/O addresses for timers or arithmetic operations. For your specific example, I1+0000 through I1+1023 are mapped to R193 - R256 with I1+0193 through I1+0208 mapped into R205. Thus, I1+0193 is bit zero of R205, I1+0194 is bit 01, etc. When converting to Rx3i, just use discrete memory or boolean symbolic variables. Whenever I've done Series Six conversions I've always referenced the Series Six address in the description of the Rx3i variable, along the lines of "was I1+0201". It helps in proofreading and debugging. You should also check the Series Six program to see if the corresponding R addresses are used anywhere. 
  3. Twin HMI screen set up

    I guess the question that needs to be asked is why is it necessary that both monitors display the same screen when an operator at either screen could easily navigate to any screen?
  4. Twin HMI screen set up

    I have never set up a system like this myself. The help files seem more geared toward multiple View Runtime targets on computers rather than multiple Quick Panels. However, there does seem to be a distinction made between clients and servers with the implication that one HMI needs to be a server and the other a client. On the client, it appears you need to set up a directory for the data shared over the network. The following is from Proficy version 9.5 help. On the Client computer, create a folder where logging, alarming, and networking files will be stored. Share the folder as 'FrameworX'. See your Operating System guide for information on how to share folders. Have you set up a directory on one of the Quick Panels and is it shared? 
  5. Hello Steve

    I'm a fellow baystater and we are in trouble with a GE PLC.  It's a 90 30 and we lost the program.  We have a backup floppy but need assistance getting it into the PLC.  Are you available for hire via phone support?

    Thank you

  7. Setting Temporary IP Address to IC695ETM001

    I don't know if it will help in your situation, but I found this discussion on the Emerson forum. https://emersonexchange365.com/products/control-safety-systems/f/plc-pac-systems-industrial-computing-forum/10614/temporary-ip-settings-for-etm001-module-in-me10-0  
  8. Setting Temporary IP Address to IC695ETM001

    Is the utility compatible with the ETM001 module? I don't know the answer to that question without drilling down into the documentation, so I only offer it as a possibility. Also, what OS are you running Proficy under? There were compatibility issues under Windows 7. The typical use for the temporary IP address utility is with CPU modules that have only an ethernet port and no serial connection. In your system you can download the hardware configuration, including the IP address of the ETM001 module through the serial port on the CPU310 module.
  9. Emerson 90-30

    The 90-30 does not support symbolic variables. It only supports address-based variables. You must assign an address to every variable you try to create. For a string your best choice will be %R addresses.
  10. Emerson 90-30

    Strings are stored in %R memory. Each %R address is sixteen bits, so there are two characters per %R address. When you look at the %R memory in a reference table you can change the display so that it interprets the bits as ASCII characters rather than as a signed integer.
  11. Upload From 90-30 without Project

    Here is a copy of what I posted in response to your question on another forum. Connect to a working PLC and upload the logic and configuration from it. Then connect to the one with no program and download. Be careful you don't mix up the direction of transfer. Proficy considers 'upload' to be a transfer from the PLC to the computer and 'download' to be a transfer from the computer to the PLC.  
  12. CCM card in series six rack

    What baud rate are you trying to use? Not sure whether or no it applies to the Series Six, but I remember in the 90-30 they recommended no faster than 9600 baud when using both ports of the CMM311 module. Also, is the CCM2 module located in the slot in the CPU rack where it doesn't need any logic in the PLC program, or does it require a rung to open the communications window? If the latter, would it require a separate rung of logic for each port? All of these questions are coming from my dim recollection of serial communications with a Series Six. It has been years since I had to do it. 
  13. Help with rx3i Modbus

    I posted a few questions for the OP at Phil Melore's site. An occasional blink of the LED on the Modbus slave port, suggests that the slave doesn't understand the command being sent by the master. It could be due to a mismatch of port settings. It could also be due to the master sending a command to a slave with a different Modbus ID than what you've set up the CMM002 for. 
  14. outputs off none off outputs on

    I'm afraid I don't fully understand your question. You might be asking if there is a way to run the program with all outputs disabled. The answer to that is, yes. You have the option to run the program with outputs enabled or disabled. You can also force individual outputs on or off. Forcing is a two-step process. First, you force the output. That action freezes it in its current state, regardless of what the program may tell it to be. After forcing you can turn it to whichever state you desire. Forcing can only be done to discrete (on/off) outputs. You can't force an analog output to a value different than what the program commands. 
  15. Unable to go online

    One other possibility: Are you running PAC Machine Edition in a virtual machine? Sometimes the COM port number assigned in the VM does not match the COM port number assigned by the host machine. If there are any LEDs on you USB/serial adapter, watch them while you are trying to establish communications. Any occasional blink of one of them indicates an attempt to communicate with no response. No LED activity indicates a mismatch between the port Machine Edition is using and the port used by the converter.
