B) If Configure Target Device is specified, the NE1A-series Safety Mas-
ter 7-segment display will show "d6" and the status code (see note 3)
(error code) shown on the Safety Connection Tab in the Monitor Device
Window will be "01:0105".
The configuration owner is cleared when the Safety Slave is reset to de-
fault settings.
Note (1) No distinction is made between Support Software, so other Network Con-
figurators can be used to configure the Safety Slave.
(2) Refer to 3-4-2 Network Numbers for information on TUNIDs.
(3) Refer to 7-1-2 Monitoring Safety Connections for information on status
codes.
Note • Reset the Safety Slave to default settings to configure from a differ-
ent configuration owner.
• The configuration owner will not match and the error listed above
will occur if the Safety Master TUNID changes because the node
address or network number has changed.
Select the connection type to use between the NE1A-series Controller and
Safety Slave.
This connection type can be selected only with a Safety Input Slave. When a multi-
cast connection is selected, a Safety Input Slave can transmit the input data to a
maximum of 15 NE1A-series Controllers via a multi-cast connection.
These NE1A-series Controllers are classified as the same multi-cast group when
multiple NE1A-series Controllers establish a multi-cast connection with one Safety
Slave and the I/O assembly and EPI values specified in I/O Connection are the
same.
This connection type can be selected even for one NE1A-series Controller.
This connection type can be selected for an input connection or output connection.
The NE1A-series Controller and the Safety Slave establish a 1:1 connection and
send safety data.
The EPI is the interval at which the Safety Controller and Safety Slave com-
municate safety data. The minimum set value is the greater of the destination
Safety Slave cycle time and Safety Controller cycle time.
a. The cycle time of DST1-series Safety Slaves is always 6 ms.
b. The Safety Controller cycle time will be one of the following values if
no default programming has been created.
• NE1A-SCPU01 (pre-version 1.0) and
NE1A-SCPU01-V1 (with unit version 1.0 or 2.0): 4 ms
• NE1A-SCPU02 (with unit version 1.0 or 2.0): 7 ms
• NE1A-SCPU01-EIP: 8 ms
• NE1A-SCPU02-EIP: 11 ms
