Use conditions
The following conditions must be met to use this function.
• The automatic address detection is functioning properly.
• In the module parameter of NZ2AW1GNAL, "Single module simplified replacement" is set to "0: Enable".
• Other slave modules than the one to be replaced have no errors.
• Slave modules having no ID except for a slave module to be replaced are not connected.
• Adjustment mode flag (RXF) is off.
Operating procedure
1.
Turn off the module power supply that is connected to the NZ2AW1GNAL.
2.
Disconnect the slave module to be replaced. (Two or more slave modules cannot be replaced at the same time.)
3.
Connect an unused slave module of the same type. ( Page 74 Precautions)
4.
Turn on the module power supply that is connected to the NZ2AW1GNAL.
A DP/DN disconnection error occurs, and DP/DN disconnection error (RX4) turns on.
5.
One slave module easy replacement in progress flag (RX16) turns on, and the backup data is restored from the
NZ2AW1GNAL.
6.
After the restoration is completed, One slave module easy replacement in progress flag (RX16) turns off, and One slave
module easy replacement completion flag (RX17) turns on.
Simultaneously, the error status of the NZ2AW1GNAL is cleared. (Same operation as Error reset request flag (RY0) turning off
and on ( Page 137 Error reset request flag))
7.
Approximately five seconds later, the One slave module easy replacement completion flag (RX17) turns off, and the
replacement of the slave module is completed.
• Unless the automatic address detection is executed, the replacement of the slave module will not be
completed successfully, and a malfunction may be caused.
• The easy replacement function for one slave module stops if an error or alarm occurs in the middle of
operation. Eliminate the cause, and follow the procedures from step 1 again.
