Table 6.3 (b)
; (Semicolon)
This is used in ladder data.
• This is used in the ladder data part to delimit ladder data
and a comment statement. Data after ";" is regarded as
being a comment statement. Consequently, when a
mnemonic file is converted to a source program, data
after ";" is not converted but deleted.
: (Colon)
This is used in ladder data and I/O module data.
• This is used in a ladder data part to delimit net numbers
and ladder data. Data before ":" is regarded as being net
numbers.
• This is used in the I/O module data part to delimit
channel numbers and I/O module data. Data before ":" is
regarded as being channel numbers.
