PL (Performance Level)
The performance level (PL) specifies the capacity of safety devices to execute a
safety function under foreseeable conditions.
PLC
A PLC (Programmable Logic Controller) is a device used to control a machine or
system and is programmed on a digital basis.
PROFIsafe
PROFIsafe Version 2.6 is used per PROFIsafe – Profile for Safety Technology on
PROFIBUS and PROFINET Profile part, related to IEC 61784-3-3 Technical
Specification Version 2.6 MU1.
PROFIsafe Address
Address that must be assigned to a safe device with PROFIsafe data
communication in order for data communication to be established between an
F host and F device.
Protected Installation
The goal of the protected installation of lines is, for example, operational reliability
and protection against stray 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.
PVi
Process Values Input
PVo
Process Values Output
R
Request
Event that causes the F I/O module to execute its safety function.
Response Time
See "Safety Response Time."
Restart Inhibit
A restart inhibit is a means of preventing hazardous machine operation from
starting automatically after one or more of the following events:
- A safety function is triggered
- The operating mode of the machine changes
- The means for staring the machine changes
