Hi James, I'm not sure if this will help but can you save your code in an L5K format (instead of saving as .ACD)? The L5K file is a text file with a format akin to XML. If you download a copy of Notepad++ from the web and then search for the Array name within the L5K you should find it . You could ...

Hi, I'm working on an RSlogix5000 V15.02 legacy system with no comments within the code. As there's numerous instances of the same UDDT in the PLC code I've written a Python script, see below. This script iterates over an L5K copy of the in-service PLC code, The script then writes a new copy of the ...

Hi Michael, I don't think you'll run into a problems with respect to the PLC code per se. You will however have a problem with your interfacing. If I'm correct your reference to SPI is the Serial Peripheral Interface - Wikipedia. This is not an interface that is designed for Industrial Control and Automation ...

I'm therefore assuming that as the suffix for the part No. is A01 then it's the older processor. Oh and with respect to the your comment regarding an upgrade this is in the ...

Thanks Fuzzy logic! In the end we bought the whole system down and then upgraded the primary CPU to 15.61 and returned the system back into service. I was hoping there was a way of forcing the firmware into the processor card. I know there's not an EPROM on the CPU but I was hoping there was way ...

Hi, My system consists of a pair of redundant racks containing 1756-L63 processors, two Control Bridge cards (1756--CNBR/E rev 11.3) and an Ethernet bridge (1756-ENBT/A rev 4.4) . One processor recently failed and we replaced it with a spare (Rev 15.61) Unfortunately our primary processor is a Rev ...
