In my small system, I am using an IC693MDL645D Input card with module addresses starting from %I00081. However, I am trying to change them to start at %I00001 but am unable to do so in the configuration. What other options can I explore to achieve this adjustment?
Is any device utilizing the %I00001 address space, such as an Analog I/O card or Communication module in Proficy ME? The software typically assigns the "next available" address automatically, but you can adjust this configuration offline if needed.
I am facing an issue with a rack containing only 3 cards - a processor, one input, and one output card. Despite my attempts to troubleshoot online and offline, including checking for dip switches, I am still confused and unable to understand the problem.
When initializing a new 90-30 project in Proficy, the default CPU374 model with an Ethernet port is selected. The Ethernet port provides 80 %I bits of status data, starting at %I00001. This means that the next available %I address for the MDL645 module is %I00081. It is possible to adjust the starting address for the Ethernet port status bits to make room for the MDL645 module. It is important to note that the PLC must be stopped in order to download a new hardware configuration. When initiating a download while the PLC is stopped, you will have the option to download the program, configuration, and initial values. However, if the PLC is running during the download process, only the program will be downloaded. Remember to stop the PLC before making any hardware changes.
While Steve makes a valid point, the starting address may not be as significant as the input's designated "Name" for programming purposes. By assigning each input a unique identifier such as In1, In2, etc., you can streamline the programming process and easily refer to each input as needed.
Thank you for your response, Steve. As a newcomer to General Electric (GE), I am eager to understand the intricacies of both the software and hardware. RussB, it is crucial for me to grasp the process behind it.
You may need to reconfigure your IO table or possibly alter the physical configuration of your system. The addressing of the IC693MDL645D Input card could be determined by its placement in your rack and can't be independently manipulated in the software. I would suggest re-sequencing your card in the system's rack or your Proficy Machine Edition IO tree to adjust it to your preferred start address. Always remember to make sure the logical and physical addresses match to avoid issues.
Have you tried resetting the base address of the PLC? This could allow you to start from %I00001. However, keep in mind that the addressing will also depend on the type of the PLC and the number of slots. Another thing to consider would be the versions of software or firmware you're using. Upgrading or downgrading might offer more flexibility with address configurations. Always remember the golden rule - back up your program before making significant changes!
It sounds like you're trying to adjust the starting address for your IC693MDL645D. Though you haven't specified which software you're using, it's worth noting that not all programs will allow you to remap existing address ranges. In some cases, you might have to remove the current module configuration and then add it again with the new address range. However, ensure you have a backup to avoid losing any configurations. If you're using GE Proficy Machine Edition, you should be able to modify the base address through the hardware configuration window, maintaining the rest of your setup. Please refer to the user manual for exact steps. I'd recommend thoroughly checking the software's capabilities and documentation before attempting any drastic changes.
