Drive AutoScan Algorithm
Connections to the drives are automatically established and continuously monitored.
No drive configuration needs to be performed to connect the ETH-100 to the drives.
Just plug it in – it's that simple.
User-Configurable Scan Registers
In order to provide faster access to internal drive data, the user has the ability to
program up to 8 ASD registers per channel to be locally mirrored within the ETH-100.
This greatly increases the speed with which accesses to these registers can be made
by the network master.
Programmable Pointer Registers
16 Modbus programmable pointer registers are provided to allow "bundling" of
disassociated registers. This allows registers which may be scattered around the
Modbus register map to be accessed by issuing only 1 Modbus transaction request.
When combined with the user-configurable scan registers, this feature provides
accessibility of any combination of ASD registers with fast response in a single
Modbus transaction.
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.
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 4 for
more information related to grounding.
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 or flash firmware
downloading.
