Chapter 5 Configure Modules with the Logix Designer Application
Safety-Readback This option creates safety and readback tags, with readback
indicating the presence of 24V on the output terminal. Safety-
Readback is not available for input-only safety modules.
Small Safety (1791DS-IB12 module
only) This option is for 12-point safety input modules that use 8 or fewer
safety inputs. The Small Safety option reduces the amount of data
that the 12-point module sends to the controller to improve network
performance. Safety data and point status tags are created. Point
status is diagnostic status for each of the eight input points.
