1 Introduction
1.1 Validity of documentation
This documentation is valid for the products PSSu E S RS232 and PSSu E S RS232-T. It is
valid until new documentation is published.
This operating manual explains the function and operation, describes the installation and
provides guidelines on how to connect the product.
The module PSSu E S RS232-T is suitable for use where there are increased environ-
mental requirements (see Technical Details).
1.1.1 Retaining the documentation
This documentation is intended for instruction and should be retained for future reference.
1.1.2 Terminology: System environment A and B
The PSSu system can be used in two different system environments. The module's applic-
ation area is described in the chapter "Intended Use" of the manual.
The distinction is made between
}PSSu in system environment A
}PSSu in system environment B
The distinction is based on the application area of the PSSu system.
PSSu in system environment A may be used in the
}Decentralised system PSSu I/O
}Not in the automation system PSS 4000
PSSu in system environment B may be used in the
}Automation system PSS 4000, e.g. with
– Decentralised system PSSu I/O with SafetyNET p
– Control system PSSu PLC
– Control system PSSu multi

2 Overview
2.1 Module structure
A module consists of
}Electronic module and
}Base module with
– Screw terminals or
– Cage clamp terminals
The base modules are the carrier units for the electronic modules and are used to connect
the field wiring. The electronic modules are inserted on to the base modules and determine
the module's function.
Details of the base modules that can be used are available in the chapter entitled “Intended
Use”.
2.2 Module features
The product has the following features:
}Serial interface: RS 232
}Communication channels: 2 (Tx/Rx, full duplex)
}Configurable transmission rates
}Receive buffer: 1023 Byte
}Send buffer: 127 Byte
}Max. number per system: 6
}LEDs for:
– Operational readiness
– Module error
– Data transmission
}For standard applications in system environment A and B
}T-type:
PSSu E S RS232-T: for increased environmental requirements
