Expansion I/O Data Mapping
This section includes I/O data mapping for the discrete, analog, and specialty
expansion I/O modules.
Discrete I/O Data Mapping
2085-IQ16 and 2085-IQ32T I/O Data Mapping
Discrete input states can be read from Global Variables _IO_Xx_DI_yy, where x
represents the expansion slot number 1…4 and yy represents the point number
00…15 for 2085-IQ16 and 00…31 for 2085-IQ32T.
2085-OV16 and 2085-OB16 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…15.
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…15.
2085-IA8 and 2085-IM8 I/O Data Mapping
Discrete input states can be read from Global Variables _IO_Xx_DI_yy, where x
represents the expansion slot number 1…4 and yy represents the point number
00…07.
2085-OA8 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.
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.
