4.6.3 Function mappings
Configuring function mappings
Some safety functions, for example the system modes, need defined safety signals
to interact with the rest of the system.
To allow the user to choose their own name for signals, these safety functions use
predefined signal aliases instead, thus ensuring that the correct signal is read.
The role of the function mappings is to connect safety signals to aliases.
Description Setting
The name of the safety function or state. Function
Defines if the safety function writes the signal or reads the signal.
Safety function writes to signal.
Safety function reads signal.
Direction
The signal that is currently mapped to the function (input, output,
or global). Signal
The source gives information on which part of the system writes
value to the signal. This can be either
Safe local I/O , Safety system ,
or user defined.
Source
The source also gives information on when a signal/alias gets its
value updated, i.e.
Safe local I/O is first and Safety system is after
the pre-logic.
True or false. Mandatory
Some mappings are mandatory since they are used by the safety
controller.
See Description of safety functions on page 97 . Description
Displays error, for example when the mapping for a mandatory
function is missing. Errors
Note
ExtComShutdownAck and SafetyEnable has no source if they are not mapped
to a signal which is written. These signals should be written to before the safety
application (e.g. device input or from pre-logic) or used with their default values.
Description of safety functions
The following safety functions are available:
Description Function
True if Automatic mode is selected. AutomaticMode
True if Commissioning mode is selected. CommissioningModeActive
i
Use this to check, in the robot controller I/O system, if
Commissioning mode is active.
