Manual
Version 1.2.0, valid from HW/SW Version 01/01
K
Cat. (category)
The category (cat.) of EN ISO 13849-1 (B, 1, 2, 3 and 4) specify the required
behavior of a safe device in terms of its resistivity to errors based on its design.
Short circuit
A practically unopposed conductive connection between two live electrical lines.
See also "Cross circuit".
Short circuit test
The short circuit test is used to discover a short circuit between two live lines.
See also "Cross circuit test".
Configuration program
The configuration program is used to configure hardware and to create the safety
program of the safe PLC.
M
Miniature WSB
The miniature WSB marking system is a quick marking system (order number
247-xxx) for WAGO connectors and I/O modules.
MTTF
D
(Mean Time To Failure Dangerous)
The MTTF
D
value specifies the mean time to a dangerous failure of a safe unit or
sub-unit.
O
Operator Acknowledge (OA)
Prompt for operator acknowledgement (OA) that evokes start-up of a machine or
system. Operator acknowledgement is necessary for the PROFIsafe I/O module,
for example, after detecting errors by the PROFIsafe I/O module and their
resolution by maintenance personnel and is monitored from the control level.
See also "User acknowledgement (Operator Acknowledge (OA))".
