I&M Functions
Reading of the I&M data from the module is possible with interface modules as from a higher
MLFB or as from a higher version than described in the following table:
Interface module
IM151-1 STANDARD
IM151-1 FO STANDARD
IM151-1 HIGH FEATURE
IM151-3 PN
IM151-3 PN HIGH FEATURE
IM151-7 CPU-F
IM151-7 CPU
IM151-7 CPU FO
Note
Use of the module after an IM151-7 CPU
If the module is positioned after an IM151-7 CPU, it outputs the last values before a RUN-
STOP transition, if no values were output by the user program after the STOP-RUN
transition.
Take this into account when programming the start-up of the control function (OB100 or
OB1).
