Instance Attributes (Instance #20, Station Name)
The Station Name identifies the Anybus module on PROFINET. If this value is changed by the host application during runtime, a reset is required in order for changes to have effect. Changes made through DCP will have immediate effect, however.
The Station Name field shall be coded as data type CHAR with 1 to 240 characters. The definition of RFC 5890 and the following syntax applies:
1 or more labels, separated by [.]
Total length is 1 to 240
Label length is 1 to 63
Labels consist of [a-z, 0-9, -]
Labels do not start with [-]
Labels do not end with [-]
The first label must not have the form “port-xyz” or “port-xyz-abcde”, where a, b, c, d, e, x, y, z = 0...9, to avoid similarity with the field AliasNameValue
Station names must not have the form n.n.n.n, where n = 0...999
Important
If the Station name does not pass validation by the Anybus module, an error response with error code 0Ch will be returned to the application and the Station name will not be changed/saved.
# | Name | Access | Data Type | Description |
|---|---|---|---|---|
1 | Name | Get | Array of CHAR | “Station name” (Multilingual, see page Multilingual Strings) |
2 | Data type | Get | UINT8 | 07h (= CHAR) |
3 | Number of elements | Get | UINT8 | F0h (240 elements) |
4 | Descriptor | Get | UINT8 | 07h (read/write/shared access) |
5 | Value | Get/Set | Array of CHAR | The current Station name If read, the actual value will be received. If written, the written value is reflected in attribute #6 until a reset. |
6 | Configured value | Get | Array of CHAR | Holds the configured value, which will be written to attribute #5 after the module has been reset. |
Important
This attribute shall normally not be set by the application. The station name is normally set by the end user via the network. The host application shall use this attribute when the end user has the possibility to edit the station name through the application, and chooses to do so.
This attribute should not be set by the application at every power on, as this would cause certification problems.
