Assign a valid seven-character alias name to any of the following:
➤ Relay Word bit (except target LEDs)
➤ Analog Quantity
Invalid alias names include the following keywords used by settings and
SEL
OGIC control equations:
➤ END
➤ INSERT
➤ DELETE
➤ LIST
➤ NA
➤ Off
SEL
OGIC control equation operators (e.g., NOT, AND, OR, COS) cannot be
used as alias names.
Alias names are valid when the following are true:
➤ They consist of a maximum of seven characters.
➤ They are constructed using characters 0–9, uppercase A–Z, or
the underscore (_).
For example, the default name for contact output OUT101 is OUT101. You
could change the default name to an alias, BK1 Trip, for example.
BK1 Trip (including the space) consists of eight characters, one more than the
allowable number of seven. Changing the name to BK1 Tr reduces the
character count to six, but the alias contains two elements not permitted, a
space and one lowercase letter (r). One possible alias for the existing name of
OUT101 could be BK1_TR, entered using the following syntax:
primitive name, alias name,
e.g., OUT101, BK1_TR
Figure 10.1 shows the steps using the SET T command.
