Before You Begin
Two Add-On Instructions are provided for the MVI56E-GSC module. The first is
required for setting up the module; the second is optional.

1.9.1 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 112).
Note: You can also set the date and time from the module's home page.
Important: The Optional Add-On Instruction supports only the two features listed above. You must
use the regular MVI56E-GSC Add-On Instruction for all other features including backplane transfer
and Modbus data communication.
