Safety Of The Machine Or System; Directive And Standards - SMC Networks EX245-FPS1 Operation Manual

2.3. Safety of the machine or system

The machine/system manufacturer and the operator are responsible for the safety of the machine or system
and the application in which the machine or system is used.
Draw up and implement a safety concept
2.3.1.
In order to use the module, a safety concept is required for your machine or system. This includes a
hazard and risk analysis as well as a test report (checklist) for validating the safety function: see

2.4 "Directive and standards"

The target safety integrity level (SIL according to IEC 61508, SILCL according to EN 62061 or
performance level and category according to EN ISO 13849-1) is ascertained on the basis of the risk
analysis. The safety integrity level ascertained determines how to connect and parameterize the module
within the safety function.
Validate hardware and parameterization
2.3.2.
Carry out a validation every time you make a safety-related modification to your overall system.
Use your test report to ensure that:
The safe modules are connected to the correct sensors and actuators.
The safe input and output channels have been parameterized correctly.
The variables have been linked to the safe sensors and actuators correctly (single-channel or two-
channel).
2.4. Directive and standards
The standards to which the module conforms are listed in the certificate issued by the approval body and in
the EC declaration of conformity
Intended use
2.4.1.
The EX245-FPS1/2/3 module is designed exclusively for use in a PROFIsafe system and fulfils the
PROFINET guidelines as defined by PI (PNO). It can only perform its tasks in the system if it is used
according to the specifications in this document.
Only use the module according to the defined technical data and ambient conditions: see
"General Specifications"
The module is designed for connecting single-channel or two-channel sensors, which can be used in
association with safety technology.
Examples of use for the module:
Single or two-channel emergency stop or safety door equipment
Applications with enable button
Applications with two-hand control devices
Applications with mode selector switches
As secondary switchgear for safety-related photoelectric barriers
Safety circuits according to EN 60204, Part 1
and see "Appendix E:
