(1) In ST programs, these data types are recognized as the following data
types.
• UNIT BCD is recognized as WORD.
• UDINT BCD is recognized as DWORD.
• ULINT BCD is recognized as LWORD.
• CHANNEL is recognized as WORD.
(2) This data type cannot be used in an ST program. A program error will oc-
cur if this data type is specified.
Array 1-dimensional array; 32,000 elements max.
