    In my project I have converted the original  *.pba HMI files into *.med project and I can run some parts of the plant however looking into the tags I notice some tags are missing, others are replaced or modified

    What is the best way to keep the tags as they are

    I have the project *.csv file from supplier but can not load it with import tool

    any idea?

    It looks like you are trying to write 2 to a digital (bool) tag, which you can only write a 0 or a 1 to.

    The tag that you are writing to needs to be an INT or a DINT, not a BOOL.

    Yes you are saying right but this program and code was written by someone else and it happened that the PLC accept this and the pump can be either OFF/MNUAL/AUTO 

    I know it may sound odd but this is it

    I looked it up real quick because your question made me curious. According to Rockwell's Knowledgebase article QA11393 (Access Level: TechConnect for some unknown reason...), the green one was used for 1746-HSCE, -HSCE2, -IO12, -NR4, -NI8, -NO8I, -NO8V, -NI16I, -NI16V modules while the red one was for 1746-IA16, -OA16, -IM16, -OAP12. The article doesn't go into any other detail about any differences between the terminal blocks.

    Page 171 of the user manual actually goes into a little more detail about which RTB to use for which module but, again, doesn't offer any details about the difference between them other than color.

    These installation instructions seem to say that the color coding is there to help you avoid accidentally connecting the wrong voltage to the module. It only asserts that you shouldn't mix-and-match when it comes to thermocouple modules.

    When replacing the module with a new one, I would loosen the screws that hold the terminal block to the module, leaving the wiring intact. The installation instructions (linked above) explain how to do that.

    Thank you for your explanation. I find it useful

    Your screenshots are from when you're offline with the PLC. You won't see the input table change unless you're online.

    For your pattern of LEDs (module status is ON while channel statuses are blinking), the troubleshooting section of the user manual (1746-UM008B) has 3 suggestions:
    1) Broken input condition (open or short circuit)
    2) Out-of-range condition
    3) Channel configuration error
    If you get online, check the processor status file register S:6 to identify the I/O error code and use the instruction set reference manual (1747-RM01) to look them up. That may help you narrow it down.

    I am sure it is something that has to be done with channel configuration because when I swap this module with the next module everything becomes OK therefore nothing wrong with the field side

    Hi,

    I have inserted new RTD module into in my SLC500 as replacement to defected RTD module however the module LED is enabled but the channel LED's are blinking.

    I have checked the following:

    In the advanced I/O configuration the module configuration is shown as expected

    In the data file word format it is not corresponding to the channel preferences

    What should I do and how to fix the word bits?

    No.

    RSLogix 500 for the SLC family + 176x MicroLogix.

    RSLogix Micro for 176x MicroLogix only.

    RSLogix 5000 for ControlLogix and CompactLogix.

    RSLogix 5 for PLC-5 family only.

    CCW (Connected Components Workbench) for Micro8xx family only.

    You must use the correct programming software.

    Thanx for the info. appreciated

    Hi

    I have established serial DF1 full duplex connection from my laptop to the SLC5/03. I am using Serial Null modem cable and it works because I can make the auto configuration in RSLinx Classic and I can see the SLC5/03

    However when I launch the RSLogix5000 there is no chance to select the path to the SLC even though it is there in the list

     

    Any help?
