1 Introduction

1.1 Validity of documentation

This documentation is valid for the product PSSu K S RS232 Modbus ASCII. 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.

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

The module PSSu K S RS232 Modbus ASCII is exclusively for use in system environment

B (automation system PSS 4000).
