About the Optional Add-On Instruction
The Optional Add-On Instruction performs the following tasks:
Read/Write Ethernet Configuration
Allows the processor to read or write the module IP address, subnet mask,
and network gateway IP address.
Read/Write Module Clock Value
Allows the processor to read and write the module clock settings. The
module's free-running clock also stores the last time that the Ethernet
configuration was changed or the last time the module was restarted or
rebooted. The date and time of the last change or restart is displayed on the
scrolling LED during module power-up/start-up sequence.
For more information, see Using the Optional Add-On Instruction (page 148).
Note: You can also set the date and time from the module's web page. See Connecting to the
Module's Web Page (page 98).
Important: The Optional Add-On Instruction supports only the two features listed above. You must
use the regular MVI56E-MNETC/MNETCXT Add-On Instruction for all other features including
backplane transfer and Modbus data communication.
