    Hello,


    My coworker and I are commissioning a new panel. We have a 1732-AENTR series C remote IO thats Rev 6.1. The project file from a previous identical panel has the module at rev5.3 in the project tree. I downloaded the AOP and ran the installer, it worked no issues. My co worker then did the same thing but now the module is unrecognized in the project tree and the module is missing after installing the AOP. Im concerned he corrupted something. I tried uninstalling and reinstalling the AOP but no luck. It works on my computer but not his? TechConnect said something about corrupting the aop core. My coworker did the first install and he was getting confused about zip files and the virtual machine we run rsl5k on. Maybe he broke it? any suggestions?

    We had an issue with a password protected PLC and after contacting the OEM they provided the password that they forgot to remove. But stealing intellectual property is illegal so you may have to factory reset the PLC and remake the program.

    So Im looking at the project file from another machine that has a similar setup and Chan. 1 - System is DH+ at 57.6k Baud, Chan. 0 - System is DF1 Full Duplex, Chan. 0 - User is ASCII 19200 baud. thats a 5/04 cpu though. Our machine in question has a 5/03. I will try the DH485 connection today but Im pretty sure our 1747 converter is broken for dh485

    I have an SLC 5/03 that Im trying to get the program from. I have a 1747-uic. Im not getting anything to show up in rslinx and I suspect the channel 0 is configured for ASCII because theres an HMI plugged into it. Also the rj45 connection is broken because someone used a crossover ethernet cable...lol. is my best bet to try and fix/replace the 1747-uic? I have an offline copy of a program from a different machine that uses a 'similar' setup and the CH.0 -System is configured for DF1 full duplex,19200,CRC and CH.0 - user is ASCII 19200 baud. Any Ideas? I was using the 3 wire db9 connector running from the HMI to the PLC. I unplugged it from the HMI and used it with the 1747, Should I use a standard DB9 cable with a null modem adapter?

    We used a photoeye to trigger a camera (sorry not allowed to go into too much detail). It then added the item to an array. I reccomend you figure out how many inches/cm or whatever of travel one revolution of your encoder is and then convert it to a ratio of 1. so say 1 encoder rev = 2 foot of item travel on the conveyor and your divert is 11 foot away from the photoeye you use to trigger the camera. so if you add your item to the array at 0.5 revs of the encoder then your item location is scan ratio + encoder revs. so you would divert at 5.5. We had an absolute encoder. converting it to a ratio of 1 makes the math way easier.

    Im not an expert but please be more specific. data types are called devices. M device is a bit. D device is a word. T = timer. If you click the help tab and look in the manuals its all explained with pictures.

    Wy back when, we used an array and sized it based on the max amount of items we could get loaded into the system + some overage then just pushed and popped to our stack. It was an array of structured data types so each item had the info we needed.
