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
)

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
Values
Baud rate
Transfer speed
9600, 38400, 57600,115200, 230400 bps
Parity
Control of the parity bit
none, even, odd
Data bits
