Two ore more single-cast safety I/O connections or a multi-cast safety I/O
connection with a different EPI has been set for a safety slave I/O.
• To share one safety slave I/O on a Safety Slave with more than one
Safety Master, make the EPI all the same and set the connection type to
Multi-cast.
• NE1A-series Safety Slaves cannot have more than one single-cast safety
I/O connection for each Safety Slave I/O. Set multiple connection paths
for the NE1A-series Safety Slave Safety Slave I/O.
• If the connection is not restored with the above remedy, delete then
re-register the connections registered to the Safety Master.
The setting for the number of safety I/O connections exceeds the upper
limit supported by the Safety Slave. Adjust the Safety Connection setting
for the relevant Safety Master. In particular, check that no more than 15
Safety Masters are set for each Multi-cast connection, with a maximum
total of 60.
The maximum number of connection IDs for one Safety Master (12) has
been exceeded.
Change the ID allocation under Edit Safety Connection – Expansion
Connection Setting to "Check Produced IDs in the Safety Slave" in the
corresponding Safety I/O Connection (Safety Input Assembly) setting, then
download the device parameters to the Safety Master again.
The Safety Slave may not have been added to the network correctly.
Check that the corresponding Safety Slave is online (i.e., the NS indicator
is flashing green or lit green.) If the Safety Slave is not online, check the
following items.
• Is the node address for the Safety Slave correct?
• Do all nodes have the same baud rate?
• Is the cable length correct (trunk lines and branch lines)?
• Is the cable disconnected or slack?
• Is the terminating resistance only on both ends of the main line?
• Is there a lot of noise?
does not match the safety signature of the Safety Slave itself.
• Reset the Safety Slave to default settings then download the device
parameters again.
• If the above remedy does not work, delete then re-register the connec-
tions registered to the Safety Master.
The TUNID for the Safety Slave monitored by the Safety Master does not
match the TUNID of the Safety Slave itself.
• Reset the Safety Slave to default settings then download the correct
device parameters.
• If the above remedy does not work, delete then re-register the connec-
tions registered to the Safety Master.
Refer to 3-4-2 Network Numbers in the DeviceNet Safety System Configu-
ration Manual (Z905) for information on TUNIDs.
The NE1A-series Safety Master is in IDLE mode, so safety I/O connec-
tions have not been established.
Change the NE1A-series Safety Master operating mode to RUN mode.
