Operation
EK1960 60 Version: 1.3.1
Fig. 52: Process data of input modules 9 and 10
The input modules 9 and 10 have a fault evaluation per channel when using the Bumper Mode, so there are
also 2 separate ModuleFault signals. When using the digital mode, both signals are set in the case of a
module fault.
Module use within the safety logic
Other than with external alias devices, only the corresponding module (two inputs or four outputs) is
assigned to the respective TwinSAFE group when selecting an input or output signal of the local
alias device. All other modules can be assigned to further TwinSAFE groups. A decoupler FB can
be used to make the inputs of a module available to a further group.
4.3.3.9 Creating the safety application
The safety application is realized in the SAL worksheet pertaining to the TwinSAFE group (SAL - S afety
A pplication L anguage).
The toolbox provides all the function blocks available on the EL6910/EJ6910.
