Safety Connection Settings Section 5-1
5-1-2 Setting Safety Connection Parameters
This section describes how to set safety connection parameters.
I/O Connections
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-series Controller is
used, the I/O assembly must be set in the Safety Slave I/O Window.
Refer to
5-2 Safety Slave Settings .
Output Connection Owner
To prevent safety outputs from an unintended Safety Master, the Safety Slave
stores data in non-volatile memory to show that the Safety Master that last
established an output connection (see note 1) is the owner of the output con-
nection. The Safety Master data that is stored is the TUNID (see note 2).
Other Safety Masters cannot open that output connection while the Safety
Slave has an output connection owner TUNID stored.
If an attempt is made, the 7-segment display on the NE1A-series Safety Mas-
ter will show “d6” and the status code (see note 3)(error code) shown on the
Safety Connection Tab of the Device Monitor Window will be “01:0106”.
Reset the Safety Slave to the default settings to clear the output connection
owner data.
Note 1. The DST1 is displayed as “Safety Output Assembly” and the NE1A-series
Controller is displayed as “Safety Output.”
2. Refer to 3-4-2 Network Numbers for information on TUNIDs.
