Gateway PROFINET IRT Slave 18
5 Configuration
5.1 Supported Size of Process Data
The gateway component for PROFINET supports an input and an output data range of 512 bytes
each:
– The first 320 bytes of each area are intended for the exchange of cyclic process data.
– The remaining 192 bytes can be used for acyclic data exchange (records).
NOTICE
Bear in mind that the maximum length of the process data is always determined by
the fieldbus with the shorter data length.
5.2 Setting Station Name
Since names are in most cases easier to handle than complex IP addresses, you can assign a
station name to the gateway component.
You set the station name using the software of your PROFINET controller.
According to the definition RFC 5890, attention must be paid to the name assignment rules:
– Data should be specified in the Octet string type.
– Limitation to a total of 240 characters (letters "a" to "z", digits "0" to "9", hyphen or dot)
– A name element of the device name must be separated by a dot and can have a maximum of
63 characters.
– No special characters such as umlauts, brackets, underscore, blanks, etc.
– The hyphen is the only special character allowed.
– The device name must not begin or end with a dot.
– The device name must not begin with numbers.
– The device name must not have the form n.n.n.n ( n = 0...999 ).
– The device name must not begin with the character string "port-xyz-" ( x,y,z = 0...9 ).
– The device name may only begin with "xn-" if the original string contains values other than "0"
to "9" and "a" to "z".
– The field "NameOfStationValue" must not end with 0.
Examples of valid names:
“device ‑1.machine‑ 1.plant‑ 1.vendor”
“mühle1.ölmühle1.plant.com“ is coded as “ xn–mhle1-kva.xn–lmhle1 -vxa4c.plant.com“
5.3 Exchanging Data Cyclically
To configure the gateway component, you have to perform the appropriate settings with the
configuration software of your PROFINET controller.
