Setting Safety Connection Parameters

This section describes how to set safety connection parameters.
I/O Connection
Select the assembly to use from the I/O assemblies that the destination Safety Slave supports.
Note: – Refer to the DST1-Series Safety I/O Terminals Operation Manual (3-2 Remote I/O Allocations) for
I/O assemblies that the DST1-series Safety I/O Terminals support.
– When the Safety Slave function of the NE1A-SCPU01 is used, the I/O assembly must be set in the
Safety Slave I/O Window. Refer to 5-2 Safety Slave Settings (page 84).
Open Type
Select the type of open processing to be performed when the NE1A-SCPU01 establishes a connection with
the Safety Slave.
Open Type
Configure the target
device
Check the safety
signature
Open only
IMPORTANT:
Note: If the Safety Slave is not configured when Configure the target device is specified, the NE1A-SCPU01
configures the Safety Slave and then establishes a connection. Therefore, the communications can
be started again just by connecting the slave to the network without the Network Configurator when
the Safety Slave is replaced. In the current version, however, the parameters to be set are only those
related to the safety application. When standard parameters do not need to be set, this open type can
be specified. The ability to set standard parameters is planned for future development.

Description
The Safety Slave is configured when the connection is established. The parameters
that can be set are limited to the parameters relevant to the safety application. Do not
use this open type under normal conditions.
The NE1A-SCPU01 sends the safety signature of the slave when the connection is
established. The safety signature is checked in the Safety Slave that receives a con-
nection is established. Specify this open type when establishing a connection with
DST1-series Safety I/O Terminals.
The NE1A-SCPU01 does not send the safety signature of the slave when a connec-
tion is established. The Safety Slave establishes the connection without checking the
safety signature. To use the slave function of the NE1A-SCPU01, it is necessary to
configure the Safety Slave correctly from the Network Configurator. If it is not correctly
configured, a connection will not be established, so there is no need to send the safety
signature from the Safety Master for checking. Only this open type can be selected
when the slave is the NE1A-SCPU01.
Check that the Safety Master and the Safety Slave are configured correctly when selecting
Open only as the safety connection open type.
