NOS (Name of
station)
Array[1..240] of Byte 0 Station name: You must occupy the ARRAY from the first
byte. If the ARRAY is longer than the station name to be as-
signed, you must enter a zero byte after the actual station
name (in conformity with IEC 61158-6-10). Otherwise, NOS is
rejected and the "T_CONFIG (Page 901)" instruction enters
the error code DW#16#C0809400 in STATUS. If you occupy
the first byte with zero, the station name is deleted.
The station name is subject to the following limitations:
● A name component within the station name, i.e., a character string between two dots,
must not exceed 63 characters.
● No special characters such as umlauts, brackets, underscore, slash, blank space, etc.
The only special character permitted is the dash.
● The station name must not begin or end with the "-" character.
● The station name must not begin with a number.
● The station name form n.n.n.n (n = 0, ... 999) is not permitted.
● The station name must not begin with the string "port-xyz" or "port-xyz-abcde" (a, b, c, d,
e, x, y, z = 0, ... 9).
Note
You can also create an ARRAY "NOS" that is shorter then 24
0 bytes, but not less than 2
bytes. In this case, you must adjust the "Length" (length of subfield) tag accordingly.
