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.
