Starter Configuration
6.1
Network Configuration Access
Starter configuration via network is only permitted when all of the following are satisfied:
•
‘N04 Net Config’ parameter is set to enable configuration via network (see table)
•
‘Local’ input (D1 or D2) is NOT asserted (or not configured)
•
Network client has recently set the Enable flag of the Configuration Command register
When configuration via network is not permitted (e.g. ‘Net Config’ disabled, ‘Local’ asserted, etc.),
attempts to configure the starter via network will raise the ‘W18 NET CONF BLK’ warning alarm.

6.2
Configuration Command Flags
The Configuration Command register [2] supports the following command flags.
Flag
Description
Enable
1 = Enable configuration operations via network. Auto-clears after 60s. Note 1.
Commit
0->1 = Save configuration settings to NVM. Note 2.
Rollback
0->1 = Recall configuration settings from NVM.
Notes:
1.
Enable must be asserted to permit other configuration commands and allow writes to the
settings objects. Enable auto-clears after 60s to reinstate configuration write protection.
2.
Commit should not be used too frequently as the internal NVM has a limited write cycle life.
6.3
Network Configuration Status Flags
The following configuration status flags [2] are supported.

“
Network Config Blocked
Net configuration operation blocked (3s T/O)
“
Network Config Error
Net config settings range error (3s T/O)
Network Diag Flags
Config Write Accepted
Recent configuration write request accepted
6.4
Configuration Errors
Should a network client attempt to write any setting outside the valid range (see [2]), the data is
discarded and a warning alarm is raised (the W19 NET CONF ERR). Attempting to start the motor will
raise a trip alarm (T19 NET CONF ERR). Other alarms can be raised should other configuration checks fail
(e.g. ‘T80 MTR AMPS CFG’ for invalid motor amps setting). A trip reset operation is required to clear
these alarms (e.g. to allow motor start). Check network client programming against the protocol map
[2].
