(0x0110)
SCOM Serial Interface Mode
The serial interface mode indicates the physical type of the serial interface used for
the SCOM communication. Available modes are RS232 and RS485. RS232 allows
a point-to-point communication, i.e. computer and Beijer Electronics RBC or Beijer
Electronics RBC and Beijer Electronics RBC. With RS485, many devices can be at-
tached to the same physical line and can be controlled by one or more computers,
allowing a kind of networking.
Limitation is given only by the physical characteristics of the RS485 bus.
This command returns the software configured serial interface mode. It is used if the
device is configured to override the DIL switch settings. This mode may differ from
the current mode in use.
Supported since Firmware Version
