Appendix B Expansion I/O Data Mapping
2085-OW8 and 2085-OW16 I/O Data Mapping
Discrete output states can be read from Global Variables _IO_Xx_ST_yy, where
“x” represents the expansion slot number 1…4 and yy represents the point number
00…07 for 2085-OW8 and 00…15 for 2085-OW16.
Discrete output states can be written to Global Variables _IO_Xx_DO_yy, where
“x” represents the expansion slot number 1…4 and yy represents the point number
00…07 for 2085-OW8 and 00…15 for 2085-OW16.
Analog I/O Data Mapping The following sections provide I/O and status mapping for the following analog
expansion I/O modules:
2085-IF4 I/O Data Mapping
Analog input values are read from Global Variables _IO_Xx_AI_yy, where “x”
represents the expansion slot number 1…4 and yy represents the channel number
00…03.
Analog input status values can be read from Global Variables IO_Xx_ST_yy,
where “x” represents the expansion slot number 1…4 and yy represents the status
word number 00…02.
2085-IF8 I/O Data Mapping
Analog input values are read from Global Variables _IO_Xx_AI_yy, where “x”
represents the expansion slot number 1…4 and yy represents the channel number
00…07.
