Variable name This is the system-defined variable name. The prefix
gives the category name.
Members (for
structures)
The member names are given for
structure only.
Meaning This is the meaning of the variable. Global/local Global: Global variable, Local: Local
variable
Function The function of the variable is described.
Data type The data type of the variable is given. Range of values The range of values that the vari-
able can take is given.
R/W access R: Read only,
RW: Read/write
Retained The Retain attri-
bute of the vari-
able is given.
Network Publish The Network Publish attribute of the

can use the vari-
able directly in
the user pro-
gram is speci-
fied.
Related instruc-
tions
