You can define the switching criteria for the monitoring cases (see "Monit
oring cases",
page 122).
Complementary analysis
A static control input consists of 2 channels. To switch correctly, one channel must be
switched inversely to the other. The following table shows which status the static control
input’s channels must have to define logical input condition 1 and 0 at the relevant
control input.
Table 3: Status of the channels of the control inputs with complementary evaluation
A1 A2 Logical input status (input A)
1 0 0
0 1 1
1 1 Error
0 0 Error
In antivalent evaluation, the 2 channels of each static control input must always be
in
verted, even if the status of a control input in a monitoring case is random. If it is not
inverted, all safety outputs switch to the OFF state and the device displays an error.
1-of-n evaluation
With the 1-out-of-n evaluation, each channel of a control input is considered individu‐
ally. At any time, exactly one channel must have logic value 1.
Table 4: True vales with 1-off-n-evaluation with 2 input pairs (example)
A1 A2 B1 B2 Result (e.g. monitoring case no.)
1 0 0 0 1
0 1 0 0 2
0 0 1 0 3
0 0 0 1 4

4.4.5 EtherNet/IP
EtherNet/IP™ (EtherNet Industrial Protocol) is an Ethernet-based network used in indus‐
t
rial automation.
EtherNet/IP™ implements the CIP™ (Common Industrial Protocol) based on the Ether‐
net and TCP/IP protocol family.
EtherNet/IP™ with the CIP Safety™ protocol extension is also suitable for safety-related
data communication.
The connection can also be used for configuration, diagnostics, and data output.
Information about pin assignment: see "Network for EtherNet/IP – CIP Safety, data
output, configuration, and diagnostics (XF1, XF2)", page 87
4.4.6 Restart interlock
Depending on the regulations which apply at the place of installation, a restart interlock
ma
y be required.
