protocol akYtec is an internal protocol and is used by the configuration software.

C.1 Addressing

The device receives an individual address so that it can be addressed selectively.

The broadcast address is a reserved address that can be used to address all devices.

The individual addresses are from 1 to 247; the address 0 is reserved as a broadcast

address.

If the device has the address 0, it is addressed with every address, but does not send a

response.

The device address is set in the parameter Addr. The factory setting is 16.

C.2 Master

Every participant may send messages. However, these are normally initiated by the master

and answered by an addressed slave.

A PLC or a PC with an RS232/485 converter and/or USB/RS485 converter can serve as a

master in the RS485 network.

There may only be one master in a RS485 network.
