Anyone ever changed PV600 with DH+ port and Printer port. to use the Printer port as either DF1 or DH485 protocol.

The 2711 B6C8 has a DH+ Card and an RS232 port for use with a printer.

I have removed the DH+ card and flashed the unit with both B6C2 (single port DH485) and B6C5 (single port DF1) firmware.

They have both successfully loaded but when the PV reboots it comes up with an error at Step 26.

I have tried this procedure with the DH+ card installed and again with it removed.
The same error occurs in both instances.


Any ideas whether it is possible to re assign the printer com port.

I can't believe AB would produce a different mother board for the variety of options in the PV600 range.
Maybe I need an option card for a B6C3(DH485 + Printer) or a B6C16 (DF1 + Printer)

Cheers

I could be wrong but I think the ASIC connector that the DH+ card plugs into is where a DF1/DH485 card plugs into the other units. The printer port is off an Aux ASIC and is either present as printer or not.

No fact just hunch to back up the above statement.

Some PanelView Standard models with RS-232 ports can be changed between DF1 and DH485 protocols. The PanelView 300 Micro is the most common model to undergo this (unsupported) change.

All other PanelView Standard terminals have unchangeable hardware identifiers that do not permit the incorrect or different firmware to be run on the terminal. A terminal built with a DH+ module, like yours, identifies its DH+ daughterboard to the runtime firmware even if the module has failed or been removed. If the runtime firmware detects that it's not built for a DH+ terminal, it will halt loading, which you have seen.

PanelView Standard terminals with a dedicated-purpose network daughtercard (DH+, ControlNet, DeviceNet, EtherNet/IP) can use the RS232 port for upload/download or as a printer port. They will not, no matter what firmware you load onto them, use the RS232 port as a runtime communication port.

Thanks Ken for your reply
Great information

I was hoping that wasn't the case.......Now I've got a couple of PV600's (DH+) which are no good for this job.
Lucky we bought them at a good price.....We live and learn.

Thanks again for the reply.




Thanks BobLfoot for your insight.

I've looked at the mother board for both model types and the No-option version (standard RS232 DF1) card looks identical to a DH+ with printer version.......albeit with the option card installed.
ie..When the option card is removed they both look the same.

Ken Roach seems to sum it up pretty well.

Rockwell wins again!!

As as addendum; the PV Standard hardware platform is about fifteen years old. One of the drawbacks of that product was that they weren't modular and couldn't be retrofitted or changed in the field. It was bad for the end-users because they had to stock a lot of noninterchangeable spares, and bad for A-B because they had to build and stock a lot of noninterchageable terminals. And these things are so durable that I'm always finding decade-old units still running strong, so A-B is going to have to build them for a very long time.

That experience with the Standard's hardware platform is the reason that the Plus has base communications hardware and modular communications. DH+, RIO, DNet, CNet, MB+, and Profibus are all option cards that connect to the back of the base RS232 or RS232 + Ethernet terminals.
