Downloading a Station

The software that handles the Ethernet Interface communication services must be loaded into each Ethernet Interface on the network. This software is loaded together with the configuration file for each station. The software can be loaded into the Ethernet Interface through the serial port (locally) or across the network.

When Must a Station Be Downloaded?

HWhen the Ethernet Interface is initially configured.

HWhen you wish to reload the Ethernet Interface with new parameters (i.e., configuration was modified).

HWhen you wish to reload the Ethernet Interface with a different software version.

HWhen an Ethernet Interface is replaced for any reason.

Note

An Ethernet Interface must be configured on the GSM before it can be downloaded by the GSM. See instructions immediately preceding.

Setting-Up the GSM and the Ethernet Interface for the Download

Start by deciding whether you will load locally or over the network. Downloading re- quires a physical connection (communication cable) between the Ethernet Interface and the GSM. This may be either the local RS-232 cable (described in Appendix B) or an Ethernet network connection.

The Network Download Mode is recommended (if you have an Ethernet Interface installed in the device running the GSM) because the time to download is less than 30 seconds. A download in Local Download Mode takes about 2 minutes due to the lower data rate of the RS±232 link.

Downloading requires cooperation between the Ethernet Interface and the GSM. Both must be in appropriate states, and both must be using the same download communica- tion facility, i.e., local or network.

Before attempting the download make sure you have fulfilled the conditions in the follow- ing table.

Note

The MAC Address and Load Source Soft Switch of the Ethernet Interface are normally determined by the Logicmaster configuration, as set in ªProcedure 3: Configuring the Ethernet Interface with Logicmaster 90-70 (PLC Module Configuration)º.
