Maximum transmission time between producer and consumer
If the safety module (F-periphery) detected an error, it switches the respec‐
tive channel or all channels of the module to the safe state. The channels are
passivated. The detected error is reported to the control.
In case of a safe input module, substitute values "0" are provided for the
safety program during passivation of the F-system instead of process values
present at the safe inputs.
In case of a safe output module, substitute values "0" are transferred to the
safe outputs during passivation of the F-system instead of output values pro‐
vided by the safety system.
Discrete level specifying the ability of safety-related parts to perform a safety
function under predictable conditions.

PL
Device sending safe data
The residual risk is the risk remaining after the protection measures were tak‐
en following ISO 12100:2011, 3.13.
Risk Combination of probability when the damage occurs and the extend of the
damage (ISO 12100:2011, 3.12).
The risk analysis is the combination of the determination of the machine lim‐
its, the identification of the danger and the risk assessment (ISO 12100:2011,
3.15).
Complete procedure covering a risk analysis and a risk evaluation (ISO
12100:2011, 3.17).
Evaluation based on the risk analysis whether the goals to minimize the risk
were achieved (ISO 12100:2011, 3.16).
Measure for the intended risk reduction
Example 1
Implemented by the designer: Inherent design, technical protection meas‐
ures, supplementing protection measures and user information.
Example 2
Implemented by the user: By organization (safe working procedure, supervi‐
sion, operating permit to perform works), provision and application of addi‐
tional protective devices (personal protective equipment, training).
Note: Following ISO 12100:2011, term 3.19.
Safe device address in a network
Discrete level (one of four possible levels) to specify the safety integrity of the
safety functions assigned to the E/E/PE safety-related system. The safety in‐
tegrity level 4 is the highest and 1 the lowest level (IEC 61508-4:2010, 3.5.8).
Specifies the current physical network of the device.
Waiting period before an error reaction is started.
