Operation
EK1960 78 Version: 1.3.1
Fig. 84: Download Project Data – The Activation dialog
In the Activation dialog the user re-enters the password to activate the safety project on the EL6910/EJ6910
or the logic component. Use the Finish button to complete the download of the safety project.
WARNING
Verification of the input and output process data
After downloading the safety-related program to the TwinSAFE logic, the user must check that the input
and output process data of the TwinSAFE logic are plausible, within the valid value range and in the ex-
pected magnitude. This is especially true for analog signals, which are transmitted via e.g. PROFIsafe,
FSoE sensors, TwinSAFE SC terminals or external control systems to the TwinSAFE logic. It is particularly
important to check whether the device uses the Motorola or the Intel format or Big or Little Endian.
Project data Description
Safe Logic Data Safe Logic Data contains the safety related program.
Mapping Data Mapping Data contains the link data for inputs, outputs, function blocks, connections
etc.
Parameter Data Parameter Data contains the safe user parameters that are stored on the TwinSAFE
Logic. These can be safe substitute values and the user parameters of the connections.
Info Data Info Data contains the settings which Info Data for connections, function blocks, groups
etc. are activated and have to be filled by the TwinSAFE Logic.
Info Data of the safety project
The Info Data will NOT take effect to the calculation of the project CRC. This allows the Info Data to
be changed at a later stage without changing the project CRC.
If the Info Data for an existing project are changed, a project download including at least the Info
Data must be carried out, despite the fact that the CRC is unchanged, otherwise the Info Data will
not be filled. In addition, the TwinCAT configuration must be activated so that the process image
size in TwinCAT matches the expected size within the TwinSAFE Logic.
