and related documentation can also be downloaded from our web site, uploaded to a unit, and custom-modified to suit a specific application.

Drive AutoScan Algorithm

ASD common serial port connections are automatically established and continuously monitored (when points are defined for that drive). No drive configuration needs to be performed to connect the ETH-100 to the drives. Just plug it in – it’s that simple.

Modbus TCP/IP Universal Access Registers

Modbus TCP/IP holding registers 9998 and 9999 provide an easy method of directly accessing any drive register without the necessity of first defining an internal point. This is typically convenient when asynchronous access to large blocks of non-control data is desired, such as when uploading or downloading an entire device configuration set over the Ethernet network. Refer to section 12.3.3 for more information.

Selectable Grounding

Switch SW1 #2 allows the ground plane to be split into 2 different sections: one for the main control circuitry and another for the Ethernet network connector shield and associated magnetics. The latter ground point is accessible for external termination via the GND screw terminal located on the bottom of the unit. Refer to section 5 for more information related to grounding.

Indicators

1 green “LNK” LED that is on whenever a valid Ethernet connection is detected.

1 red “ACT” LED that flashes whenever data is transferred across the Ethernet network.

1 bicolor red/green “MS” LED that indicates module status information.

1 bicolor red/green “NS” LED that indicates network status information.

2 green LEDs on each of the drive communication connectors and on the MMI port connector.

Refer to section 9 for more detailed information about the LED indicators and their meanings.

MMI Port Connector

RS232-level. Use the DB9-to-RJ45 MMI cable supplied with the ETH-100 kit to interface with the unit for either console-based configuration, point file upload/download, or flash firmware downloading.

Field-Upgradeable

As new firmware becomes available, the ETH-100 unit can be upgraded in the field by the end-user. Refer to section 14 for more information.
