5.14.2 DHCP server configuration
When using DHCP it is possible that every MDX-ETHERNET re-initialises it will receive
a new IP address. This will make it difficult to keep track of what IP address is allocated
to a particular module and when using a Modbus IP master this would also require
reconfiguration.
LEROY-SOMER recommend that the leased IP address for MDX-ETHERNET is
allocated to MDX-ETHERNET MAC address. This will prevent MDX-ETHERNET IP
address changing when it re-initialises or when the DHCP server renews the MDX-
ETHERNET lease.
5.15 MDX-ETHERNET operating status
Operating status
This parameter gives operating status of MDX-ETHERNET, a value of 2 (inactive
network process data) indicates that MDX-ETHERNET is initialised and ready to
communicate. For more information see section 12.7 Fieldbus option state.
5.16 Re-initialising MDX-ETHERNET
Re-initialising MDX
Changes to the MDX-ETHERNET configuration will not take effect until the MDX-
ETHERNET has been re-initialised.
To re-initialise MDX-ETHERNET:
1. Set Pr 15.32 to ENABLED.
2. Before the reset takes place Pr 15.32 will be reset to DISABLED.
3. The MDX-ETHERNET will re-initialise using the updated configuration.
5.17 Saving parameters to the drive
Drive parameters are automatically save if is change by keypad or PC software.
If parameters are change by Ethernet :
To avoid loss of the configured settings when the drive is powered down it is necessary
to store the parameters.
To store drive parameters:
•Set Pr 11.65 to 0. (See note regarding drive).
•Set Pr 11.64 to yes (1).
•if 11.64 returns to no (0), the storing is finished.
Pr 15.06
Default N/A
Range 0 to 14
Access RW
Pr 15.32
Default 0 (DISABLED)
Range 0 to 1
Access RW
This sequence does NOT store the MDX-ETHERNET configuration parameters in the
host drive.
Pr 15.32 will revert to OFF immediately and may not be visible on the display.
NOTE
The drive will store all the drive parameters but the operation of MDX-ETHERNET will
not be affected. Any changes made to the MDX-ETHERNET configuration parameters
(mapping etc...) will not take effect until the MDX-ETHERNET module is reset.
NOTE
