1. Two or more output safety I/O connections have been set for the Safety
Slave.
• Change the Safety Connection setting for the Safety Master so there is
only one connection. Then reset the Safety Slave to default settings and
download the device parameters to the Safety Slave again.
2. The same output assembly number for a Safety Slave has been used for
both a Safety Master and a Standard Master.
• Input assembly numbers can be duplicated but output assembly numbers
cannot. Check the Safety Connection setting for both the Safety Master
and the Standard Master then return the Safety Slave to default settings
and download the device parameters to the Safety Slave again.
• If the error remains even after the above countermeasure has been
performed, delete and 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 30.
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 Safety Slave is configuration locked and Configure the target device is
selected for the Open Type setting for the Safety Master connection.
• Release the configuration lock on the Safety Slave to configure the
Safety Slave from the Safety Master.
• To configure the Safety Slave from a configuration tool, set the Safety
Master connection to Check the safety signature under Open Type. Then
reset the Safety Slave to default settings and download the device
parameters to the Safety Slave again.
