Character Strings
Notations for characters strings in item contents are as follows.
• The valid/invalid value (Boolean) is notated as OFF or ON.
• The string itself is shown as-is.
• Values are written as decimals. However, hexadecimal is used to notate
significant bits when present.
• The alarm levels of reference channels are expressed as valid channel numbers
(01, 02, etc.).
• The choices are given by the name of the string. They are expressed as
character strings, abbreviated as much as possible while retaining their
usefulness for identifying mnemonics for constants.
