Beckhoff BC-9000 nonvolatile (remanent) variables working ex

Can someone share some tested example of working with nonvolatile storage in Beckhoff BC series PLC? All I need is to keep few vars through power-off and allow remote UI to read it out at startup and set them when necessary. Is there any way other than "shadowing" them in RAM, read at startup and co...

Well. It was easy. Figured it out using multimeter in a minutes, once opened PLC case and found microcontroller datasheet. Used handy RS-232-TTL converted board to build programming cable, works perfectly.

hello, it is nearly the same cabel as beckhoff. Glad to hear this... But does anyone know enough about it to be able to build one from junkbox parts? ;) My junkbox is pretty rich, of course, I can pull something starting from vintage military low inductance high power RF load resistor (with berilli...

[?]: WAGO 750-920 Communications Cable pinout/signal levels

Hello everyone! I'm looking for any information concerning WAGO 750-920 Communications Cable - schematic or pinout + signal levels would be ideal (plan to build one). Just got 750-816 unit with a handful of i/o modules from some dismantled equipment and like to use it to advance my PLC programming s...

Looks like you mean BK9000... It looks really just remote I/O unit, according to specs. BC9000 has built-in PLC, if Beckhoff website is corect... ;)

[?]: Beckhoff BC9000 cloning

Just got a question from a friend, but have no experience with Beckhoff equipment at all. There is two exactly identical machines, controlled by BC9000 PLC with a few I/O modules (both analog and discrete). After a nearby lightning hit, Ethernet port on one of BC9000 went bad. Everything is working ...
