Description Term
Discovery Control Protocol. A protocol that allows the master controller to find every
PROFINET IO device on a subnet. DCP
Digital input DI
Frequency converter for controlling AC motors Drive
Electromagnetic compatibility EMC
Emergency stop E-stop
Function that is initiated when a fault within the safety component is detected by the
component's diagnostic function. (62061-3.2.18, modified) Fault reaction function
Failure in time: 1E-9 hours (IEC 61508) FIT
General Station Description file, an ASCII-format device description file in a specified
form. Each different slave type on the PROFINET IO network needs to have its own
GSD file. GSD files in PROFINET IO are written in GSDML. GSD file
Insulated gate bipolar transistor IGBT
Least significant bit LSB
Media Access Control address MAC address
Media redundancy manager MRM
Media redundancy protocol MRP
Most significant bit MSB
Mean time to dangerous failure: (Total number of life units) / (Number of dangerous,
undetected failures) during a particular measurement interval under stated conditions
(EN ISO 13849-1) MTTF
D
Average probability of dangerous failure on demand (IEC 61508) PFD
avg
Average frequency of dangerous failures per hour (IEC 61508) PFH
Performance level. Levels a...e correspond to SIL (EN ISO 13849-1) PL
Programmable logic controller PLC
Adjustable speed electrical power drive system suitable for use in safety-related ap-
plications Power drive systems
(Safety-related), PDS
(SR)
Adaptation of a communication protocol for a certain application field (for example
drives) Profile
PD, Process data PZD
Systematic capability (IEC 61508) SC
Safe failure fraction (%) (IEC 61508) SFF
Safety integrity level (1...3) (IEC 61508) SIL
Maximum SIL (level 1...3) that can be claimed for a safety function or subsystem
(IEC/EN 62061) SILCL
Safe stop 1 (IEC/EN 61800-5-2) SS1
16-bit or 32-bit word from a controlled device to the controller with bit-coded status
signals Status word
Safe torque off (IEC/EN 61800-5-2) STO
Proof test interval. Defines the probabilistic failure rate (PFH or PFD) for the safety
function or subsystem. Performing a proof test at a maximum interval of T1 is required
to keep the SIL capability valid. The same interval must be followed to keep the PL
capability (EN ISO 13849) valid. Note that any T1 values given cannot be regarded
as a guarantee or warranty. T1
