Function Description
CPU
The CPU controls the outputs, reads the inputs and processes / stores the
user program and variable data. The failsafe section is designed to be
multi-channel, i.e. different CPUs process the user program independently.
A four-digit display and several LEDs provide information on the status of
the safety system and indicate any errors.
Interfaces
CPU interfaces
The CPU of each programmable safety system in the PSS 3075-3 series
provides the following interfaces:
• Programming device interface
Combined RS 232 interface (minimum configuration: TxD, RxD, GND)/
RS 485
• User interface
Combined RS 232/RS 485 interface (termination is selectable)
For further information please refer to the “System Manual for the
PSS-Range”.
SafetyBUS p interface
The programmable safety system from the PSS 3075-3 series may have a
SafetyBUS p interface, depending on the unit type. For further information
on SafetyBUS p, please refer to the “System Manual for SafetyBUS p”.
Interfaces for standard bus systems
Different interfaces are available for connection to various standard bus
