Serial connection
The entire range of (carel)ir33 models has an RS485 serial port for connection to
supervisor or telemaintenance systems using a two wire plus shielded cable via a
serial network.

That's an excerpt from 4+Mb user manual pdf.
Shall You specify exactly what's needed I may dig further.

Hi Kas!

I have Rittal DK 3124.200 controller which have Carel procol embedded. I developing Carel protocol to MODBUS convertor, but I have nothing about Carel even in Rittal documentation.
(I expect answer from Rittal technical support, but main engineer is on vacation for two weeks. To long to wait, even positive result is not shure)

9.1.2 Phase 2, semi-automatic assignment of the addresses
At this point, the controllers to be included in the network must be added.
The program runs the automatic address assignment procedure, sending the
following command in the network;

<‘! ‘>

Where
= 0 so that the command is received by all the controllers.
This is performed only by the controller in address assignment status, and when the
command is received, the unit:
• saves the new serial address,
• sends the response packet to the PC,
• displays the address received;
• qexits the address assignment procedure.
The command, received from an instrument with
<> 0, assigns the new
value contained in
for the serial address.
The response to the PC is the same as the request for the software version <‘?’>:

<‘V’>[]

Shall something like this do - if yes, will copy and pass through PM. Some pages in PDF, 1-2 Mb.
As for physical part, looks like CAREL uses external logic to serial adapter box. Must be something generic.

Hi mbruck
Have you been able to solve this problem?
I have a Rittal coolong unit and need to comunitate it with a TWIDO PLC in Modbus RTU RS485.
Thanks!
