Status Files
To access Status files, specify a word (and optionally, a bit in the word). The default data type for all syntax is
shown in bold.
Syntax Data Type
S:<word> Short, Word, BCD, DWord, Long, LBCD
S:<word> [rows][cols] Short, Word, BCD, DWord, Long, LBCD*
S:<word> [cols] Short, Word, BCD, DWord, Long, LBCD*
S:<word>/<bit> Boolean
S:<word>/<bit> [rows][cols] Boolean*
S:<word>/<bit> [cols] Boolean*
S/bit Boolean
S/bit [rows][cols] Boolean*
S/bit [cols] Boolean*
*Array types
Note: The number of array elements (in bytes) cannot exceed the block request size specified. This means
that array size cannot exceed 16 words given a block request size of 32 bytes. For more information, refer to
Block Request Size.
Word Locations
The following Word locations are allowed for each model. The maximum word location is one less when access-
ing as a 32-bit data type (Long, DWord, or Long BCD).
PLC Model Max. Word
SLC 5/05 Open 999
PLC-5 Family 999
