Hey don't worry about it. I understand most of these documents were before PCs were mainstream and so were most likely never digitized. This project is just for fun anyways so there is no worry about striking out. Thanks again! ------------------------------ --ATL--[Designation] -- ...

I have actually tried both. An older computer with a dedicated serial port, as well as a "modern" computer requiring a USB to serial adapter and I get the same response. Looks like it may be time to scour eBay for an old manual. ------------------------------ --ATL--[Designation] ------------ ...

I am attempting to connect to an Allen Bradley PLC-1 (1774 Series). I am connected serially to a 1770KF2 unit. The 1770KF2 unit is connected to my PLC-1 Via a 1774-KA (Data Highway Communication Adapter). That is just a straight blue hose Datahighway cable. I am able to detect the KF2 terminal unit ...

Is there anywhere I can find / be provided the ICOM AI-2 software error codes? Currently I am getting the following: Rrror PCL_LINK_STATUS return an error code of 16 Description Status Error 10 DIAGCODE:81 Severity The current operation can not be completed ...

I'm still looking if anyone has any. In the same vein I would also be interested in the Bulletin 1750 (PMC) manuals as well. Whether that's the PMC or Mini PMC. So if anyone is cleaning out an old closet in Milwaukee or Cleveland keep an eye out! ------------------------------ --ATL-- ------ ...

Unfortunately no the 1774 is before the Plc-5 and even before the Plc-2. From what little I am able to find it was the. Controller after the 1750-pmc. It's chassis looks like either 1774-rp3 or 1774-lp3. If you search Google you can see some pictures. All references to manuals I have found ...

Anyone have any Bulletin 1774 manuals available to them online? I would be interested in looking at 1774-800 just for curiosity sake, but anything to do with the 1774 series PLCs and hardware would be interesting. I am looking for them as to learn about legacy AB PLCs and think it would be interesting ...
