Yelrow Posted October 1, 2023 Share Posted October 1, 2023 i am afraid, i have never heard of one. Link to comment Share on other sites More sharing options...
Going Spare Posted October 1, 2023 Share Posted October 1, 2023 Thank you - having Google'd it, I am just a little wiser! I am too 'old school'; I do not see the fun in technology controlling everything, if I have interpreted a PLC's use correctly. Link to comment Share on other sites More sharing options...
What About The Bee Posted October 1, 2023 Share Posted October 1, 2023 I could see using a PLC to switch signals on a DC layout. I've used them in other, professional applications and could easily see them used there. Yet for a DCC layout, the logic would be better located elsewhere.Bee Link to comment Share on other sites More sharing options...
atom3624 Posted October 1, 2023 Share Posted October 1, 2023 I suppose by applying it's definition, it could be used to program the characteristics of individual locomotives - pure smooth power for electrics, delayed response for diesels, etc .. ??Al.

Topcat2018 Posted October 1, 2023 Share Posted October 1, 2023 In their simplest form PLCs consist of a PCB with a microcontroller and a number of relays on it. They can be programmed to switch the relays according to the program and also in response to digital inputs. The more sophisticated ones have analogue inputs, and analogue outputs that I suppose could be used to control the speed of DC locos.The more sophisticated ones aren't cheap, but cheaper than a typical loco.Not something I use myself. If I want something programmable I use Microchip PIC microcontrollers on a home-made PCB or prototyping board. Link to comment Share on other sites More sharing options...
96RAF Posted October 2, 2023 Share Posted October 2, 2023 Microchip devices are used in many bits of Hornby kit, Controllers, Acc Decoders, etc.Here is an PicKit updater being used on an R8247 to bring it to v2.0. Link to comment Share on other sites More sharing options...

ColinB Posted October 2, 2023 Share Posted October 2, 2023 I can see where you are coming from Dukedog, I imagine a lot of the large exhibition layouts must use them. Link to comment Share on other sites More sharing options...
The son of Triangman Posted October 3, 2023 Share Posted October 3, 2023 Loads of uses for PLC'S on layouts, level crossings, signals, points etc . I sometimes dabble with PIC programming of MCU's. It's mainly 8 bit and 16 bit stuff nowadays. I left embedded software work behind years ago and now it's a hobby related thing. I am a bit greedy as I have enough kit to program 4 MCU's at a time including PLCC'S. I tend to still use 8 bit 12f83 and 16f84 micro controller ic's Link to comment Share on other sites More sharing options...

96RAF Posted October 3, 2023 Share Posted October 3, 2023 The loco detection kit I use has sensor isolation that uses AT2313A processors. The Txs gather sensors data and send their signals via fibre optic each to a daughter Rx mounted to a motherboard that talks to the PC running TGG.
