Protocol Structure - Ethernet; Process Interface Via Rs485 (Device Dependant); Configuration Of The Rs485 Interface - Baumer VeriSens ID Series Technical Documentation Manual

15.1.2 Protocol structure – Ethernet
After you have established a connection with the device via the set port, you can request data from the
device or transfer commands. To do this, you may use the device protocol. This consists of a 2-byte
command code followed by the parameters and the actual data.
The datagrams may also be terminated with the following control characters:

<CR> (Hex: 0D, Escape sequence: \r)

<LF> (Hex: 0A, Escape sequence: \n)

<CR><LF> (Hex: 0D 0A, Escape-Sequence: \r\n)

without

15.2 Process interface via RS485 (device dependant)

You can communicate directly with the device via an RS485 connection.

15.2.1 Configuration of the RS485 interface

The integration of the device via the process interface is made with an RS485 connection. For this purpose,
connect the device with your machine using the pins provided and set the RS485 parameters using the
Application Suite.
The following parameters are available with which the physical transfer is controlled:
Parameters Description
Baud rate Transfer speed
Parity Control of the parity bit
Data bits Number of bits per character
Stop bits Number of stop bits as end code
The following parameters are also required to control the logical transfer of the process data:
Parameters
Device number
Protocol
Result
Receive timeout
Response delay
