VARIOUS SETTINGS
Overview of the parameter setting procedure
1.
Preparation
Perform the following before parameter settings.
• Configure the system.
• Start the engineering tool.
• Set the Safety CPU to the test mode.
For details on the test mode of the Safety CPU, refer to the following.
 MELSEC iQ-R CPU Module User's Manual (Application)
2.
Network Configuration Settings
Write the network configuration settings to the CPU module.
3.
Parameter processing of a device station
Perform the parameter processing of device station. Perform the operations to all safety remote I/O modules connected.
4.
Safety Communication Setting
Write the safety communication setting of the master station to the CPU module.
5.
Checking the position of the setting target module
Perform the checking of the position of the safety remote I/O module where the parameters are set. Perform the operations to
all safety remote I/O modules connected.
6.
Safety module validation
Switch the safety remote I/O module to the state where safety communications are enabled (safety operation mode). Perform
the validation as a final check before the safety remote I/O module operation (a check whether parameters are written to a
module as intended). Perform the operations to all safety remote I/O modules connected.
• Write the safety communication setting to the CPU module after completing "Parameter write" to all safety
remote I/O modules connected. Failure to do so may cause an error (parameter mismatch of CPU module
and safety remote I/O module) in the CPU module at the restart of the safety remote I/O module.
• No restrictions are provided on the access level for writing parameters to the safety remote I/O module.
However, when the access level is "Assistant Developers" or "Users", even though parameters have been
set to the safety remote I/O module, safety communications are disabled because the safety
communication setting cannot be configured in the CPU module. To perform the safety communications,
configure the setting with "Developers" or a higher access level. For details on the access levels, refer to the
following.

• If the safety remote I/O module is left with "Safety module validation" not being performed for 10 minutes or
longer, a moderate error (safety module validation not performed) occurs.
• "Safety module validation" cannot be performed while the moderate error (safety module validation not
performed) persists. To perform "Safety module validation", eliminate the error by restarting the safety
remote I/O module.
• For the NZ2GFSS2-8D-S1, NZ2GFSS2-8TE-S1, or NZ2GFSS2-16DTE-S1, "Safety module validation"
cannot be performed while the moderate error (parameter data error) caused by parameter settings
persists. If "Safety module validation" is performed, the minor error (safety module validation failure) occurs.
For details, refer to the list of error codes. ( Page 138 List of Error Codes)
• Since the safety remote I/O modules use the remote register areas for safety communications, assign the
remote register areas. ( Page 175 Remote Register)
