5 Configuration and Startup
5.2 Configuration of LioN-P
PROFINET Modules in TIA Portal
The following options are available
D
Set Low – Deactivation of output channel (digital value = 0)
D
Set High – Activation of output channel (digital value = 1)
D
Hold Last – Holds last output status (digital value corresponds to last
status)
Surveillance Timeout Configuration (ms)
These parameters are provided to all module types with digital outputs. The
configuration can be used to set a delay time (Surveillance Timeout) that
defines the monitoring procedure for the individual digital output currents for
each channel.
The delay time starts after a change to the output channel status. If an output
is activated (rising edge) or deactivated (falling edge) the output monitoring
does not start until the delay time expires. Any fault conditions that arise after
this delay are registered by the diagnosis.
The adjustable value range for the delay time is 0 to 255 ms. The default value
is 80 ms. When the output channel is in the static state, (channel permanently
switched on or off) the value is 100 ms.
IO Mapping Configuration (for 16DI/DO Modules Only)
Configuration of the IO mapping makes it possible to change the data
structure of the I/O data. By default each I/O channel is mapped in sequence
in the process data. Existing PLC programs however, may under certain
circumstances, use another channel assignment.
These parameters enable all I/O channels to be freely assigned a bit in the I/
O data. It should be noted that duplicate assignments are not possible here. If
faulty parameterization of the IO mapping when transferring the configuration
is detected,the LioN-P module registers a fault.
5.2.5 Fast Start-Up (FSU) / Prioritized Start-Up
The LioN-P modules with Fast Start-Up (FSU) support an optimized system
start-up. This guarantees a faster restart after the power supply is restored.
Fast Start-Up can be activated for the LioN-P modules with
