InfraRed with PLC

[danw]

Actisys makes IrDA devices, many for Windows platforms, plus some software tools.

Somewhere on their site, I remember seeing an IrDA tutorial

Here's a kit that can detect a IR transmitter and toggle a relay. The relay contacts can be wired to any input on the PLC.

Here's another that has 10 relays.

there's more...

Better yet (IMO) go for RF remote control. Line of sight not necessary, & better range.

None of this is rs-232, but it might be better suited to a home project, and a lot less expensive.


Have fun..

How about a PLC with an ethernet port. You could then hook that up to a wireless ethernet port. You could then get a Palm Pilot with a wireless ethernet card. Write VB app that runs on CE. Write communication driver instead of trying to use RSLinx. Yeah, I know, sounds tough, but now you could turn off appliances after you left the house.

I think Palm Pilot has different OS (it is not Windows CE) so VB program can not be used. PocketPC may be required (which is more expensive compared to Palm) for using VB program.

Ir - Plc

Flukie?

Just out of curoisity, what do you want to have the PLC 'control'? room lights, heat/AC control, etc.? I'd suggest you take a quick look @ X-10's web site, for some info. Also, years back there was a product named "Butler-in-a-box", not sure if its still out there tho'

RC5 to RS232 conversion

I only recently come accross this forum and was fascinated to read the discussion about converting RC5 to RS232 codes. At the risk of appearing to be advertising I have designed and built small units for my own firm for the audio visual trade. They usually respond to our own IR codes but decoding RC5 is also possible. The incoming IR information doesn't have to be related to the outgoing RS232 codes in any way because the RS232 data is stored in a look up table in the convertor.

Relay contact outputs can also be fitted to respond to input commands.
