If there are slaves for which the node address is not set (i.e., for which the present value is 0) or
if there is more than one slave with the same node address (indicated by "!"), change the set
values of the slave addresses, and then click the Write Button.
(If the correct node addresses are set for all of the slaves, click the Cancel Button.)
The node addresses are written to the actual slaves.
Additional Information
• The switch setting is read only once when the power is turned ON. Even if the setting is
changed after the power supply is turned ON, the new setting will not be used until the next
time that power is turned ON.
• If same node address is set for more than one node, a Slave Node Address Duplicated Error
occurs and the operation of the slave stops. If a duplicated node address is set, the system-
defined variable _EC_SlavAdrDupErr (Slave Node Address Duplicated Error) changes to
TRUE.
• Use the Sysmac Studio to set the node address if there are no hardware switches or the node
address is beyond the range that can be set with the hardware switches.
