5.3.3 EP1957-0022: using the integrated TwinSAFE Logic
functions
Does not apply to EP1957-2222
Since the EP1957-2222 variant is a pure I/O component, this chapter does not apply to the
EP1957-2222.
On delivery, the EP1957 behaves like a safe TwinSAFE I/O slave, which can be used as an alias device
within a TwinSAFE Logic, e.g. EL6910.
Alternatively, the local logic function of the EP1957 can be used. To this end please create a TwinSAFE
project in the Safety Editor and select the EP1957 as the target system. Further information on creating a
project can be found in the EL6910 documentation and the description of the function blocks under http://
www.beckhoff.de/german/download/twinsafe.htm.
In order to be able to use the EP1957 again as a safe TwinSAFE I/O slave, please delete the logic, the
mapping and the parameter data on the EtherCAT Box and switch the voltage off and on again.
