16.1 Parameters in the I/O configuration
Group: Function model
Parameter Description Default value Unit
Function model This parameter is reserved for future functional expansions. Default -
Table 14: I/O configuration parameters: Function model
Group: General
Parameter Description Default value Unit
System behavior when a module is missing On - Module supervised
Parameter value Description
On A missing module triggers service mode.
Off A missing module is ignored.
Module information
(up to AS 3.0.90)
This parameter enables/disables the module-specific information in the I/O
mapping:
• SerialNumber
• ModuleID
• HardwareVariant
• FirmwareVersion
Off -
This parameter enables blackout mode (see section Blackout mode in Automa-
tion Help under: Hardware → X20 system → Additional information → Black-
out mode).
Off - Blackout mode
(hardware upgrade 1.10.0.6 or later)
Parameter value Description
On Blackout mode is enabled.
Off Blackout mode is disabled.
Channel status information This parameter enables/disables the channel-specific status information in the
I/O mapping.
On -
State number of 2-channel evaluation This parameter enables/disables the status information of dual-channel evalu-
ation.
Off -
Restart inhibit state numbers This parameter enables/disables restart interlock status information. Off -
SafeLOGIC ID In applications with multiple SafeLOGIC controllers, this parameter defines the
module's association with a particular SafeLOGIC controller.

Max switching frequency channel x
(up to firmware version < 300)
Maximum switching frequency of the output channel.
• Permissible values: 1 Hz, 10 Hz, 100 Hz, 1000 Hz
This value specifies the max. switching frequency of the actuator connected to
the output. It is especially important to adjust this parameter to the actual con-
ditions for inductive or capacitive loads because the internal delay for checking
the voltage to see if it is 0 V after a cutoff signal occurs is calculated using this
parameter. Therefore, if this value is too high (e.g. 1000 Hz) and the voltage
does not go to 0 within the corresponding time (in this example 500 µs) after a
cutoff signal because of the connected actuator, then a channel error occurs.
If the output is controlled by the application using a higher switching frequency
than configured, a channel-specific error may erroneously be detected on the
module, which causes the channel to be cut off.
1 Hz
Table 15: I/O configuration parameters: General
Group: Output signal path
Parameter Description Default value Unit
This parameter specifies the mode that can be used by the standard application
to access the output channel.
Direct - DigitalOutputxx
Parameter value Description
Direct The output channel can be accessed directly by the standard application. Signals
"DigitalOutputxx" are available in the I/O mapping accordingly.
Via SafeLOGIC The output channel cannot be accessed directly by the standard application. Signals
"DigitalOutputxx" are not available in the I/O mapping accordingly. It is only possible
for the standard application to influence the output channel via the communication
channels from the CPU to the SafeLOGIC controller.
