Hardware: PSR-TRISAFE-S safety module
103503_en_03 PHOENIX CONTACT 3-11
3.5 USB interface
The USB interface (standard USB 2.0) is used for communication between the
PSR-TRISAFE-S safety module and the SAFECONF configuration software.
This includes:
– Downloading configuration data (i.e., the SAFECONF project)
– Optional upload of the configuration in order to open it as a project and edit it as
required in SAFECONF
– Reading values from the safety module during operation and displaying the read values
"live" in the connection editor of SAFECONF (online mode)
– Forcing signals on the running safety module for startup purposes (standard startup
mode)
Once the USB connecting cable (mini-USB connector, 5-pos., maximum cable length 3 m)
has been connected, the appropriately configured PC detects the safety module
automatically.
If the SAFECONF configuration software is already running, the software detects the status
of the safety module and indicates it at the bottom right in the status bar.
Figure 3-7 Status bar in the SAFECONF configuration software (safety module already
contains a configuration project)
Before the PSR-TRISAFE-S safety module is connected to the configuration PC, the
SAFECONF configuration software must be installed with the appropriate USB drivers for
the module.
NOTE: Electrostatic discharge
The PSR-TRISAFE-S safety module contains components that can be damaged or
destroyed by electrostatic discharge. When handling the USB interface, observe the
necessary safety precautions against electrostatic discharge (ESD) according to
EN 61340-5-1 and EN 61340-5-2.
