Last Contrologix to support DF1

The 1756-L6x and 1756-L32E/L35E supported DF1 through their onboard RS-232 ports.

The 1756-L7 and -L8 and all of the subsequent CompactLogix have USB instead.

There's a 5069 serial module, but I'm not sure what DF1 features it provides.

Do you need a specific variant of DF1 (Half Duplex, Radio Modem, etc) for a telemetry application ?
 
The 5069 was rumored to have a DF1 module coming out last September but nothing has appeared.

I have an L61 that can do it, was just hoping for something more current. I don't really want to use a gateway, this will only run for a year or two while existing radios are replaced.

Ken this is for existing F/D telemetry so I guess using the existing L61 makes the most sense. I have to buy a new proc for the new project anyway, it would have been cleaner to just have DF1 in the new proc, but alas, 2 procs and 3 EN2T in a rack it is...
 
A little old school?:

Have a nice, new Ver 32 CLX Ethernet message to a SLC5/05 and program the 5/05 as a bridge to communicate DF1.
 
Right - but someone up the chain said DF1 was coming to that platform - just never happened.

My understanding is that its a patent/licensing issue with AB that keeps others from opening up possibilities in this space. Not enough call for an outsider to pay the licensing to do it for a reasonable cost and AB can therefore hold it hostage... and not do it at all.
 
The claim from our automation specialist is that the 5069-SERIAL module will receive a firmware update that will allow it to support DF1 protocol in March, but I would not count on that until it has happened and been thoroughly vetted.

I believe there is a USB to serial adapter, no? So even if your PLC is using USB or serial, you can communicate with your laptop with the adapter?

I believe the USB port on AB PLC's is for programming only. They aren't "PLC to PLC" communication ports. Plus, in order to get a USB to Serial adapter to work you would need there to be a driver installed on the PLC which doesn't exist.

I gotcha, thanks for your input. I wonder when Allen Bradley will decide to incorporate their PLC products with Windows, maybe then we can start doing some real crazy things! Price will be astronomical though.
