WAGO-I/O-SYSTEM 750
753-661/000-003 4FDI 24V PROFIsafe V2 iPar
PROFIsafe V2 Mode acc. IEC 61784-3-3
PROFIsafe V2 Mode – Services and protocols of the safety-oriented PROFIsafe
communication profile according to PROFIBUS Guideline: PROFIsafe – Profile
for Safety Technology, 2.4, March 2007.
PROFIsafe Address
Address that must be assigned to a safe device with PROFIsafe data
communication, so that data communication can be established between a
PROFIsafe master and a PROFIsafe slave.
Proof Test
Proof test or recurring test that is performed to discover failures in a safety-related
system, so that the system can be brought to a "like-new state" or as close as
possible to this state from a practical perspective.
Proof Test Interval
The proof test interval is the time until testing the safety function / safety device is
required.
Protected Installation
The goal of the protected installation of lines is, for example, operational
reliability and protection against vagabond voltages at different voltages in a cable
or equipment. Among other means, this is achieved by the necessary insulation
between two lines of different potentials.
R
Request duration
Minimum duration of a signal voltage "0" (e.g., open input) on the input of the
PROFIsafe I/O module
Requirement
Event that the PROFIsafe I/O module causes to execute its safety function
Restart Barrier
A restart barrier is a means of preventing hazardous machine operation from
starting automatically after one or more of the following events:
- Triggering of a safety function
- Changing of the operating mode of the machine
- Changing of the means for staring the machine
Risk Reduction
The required risk reduction is the result of a risk assessment that is used to take
measures to lower the risk of a security system to an acceptable residual risk.
