Bit 15: Reserved –

State ignored.

Bit 14: OUT1_Function –

“0” configures Output 1 to be a Fault Output. The output will conduct current

until a fault occurs. “1” configures Output 1 to be a general purpose output whose state is determined
by a bit in the Command Mode Network Output Data. This output is in an ON state when power is
applied to the Networked Driver and it has not yet been configured.

Bit 13: OUT1_Action_on_Connection_Lost –

“0” will keep Output 1 at its last value. “1” will set the state

of Output 1 to the value specified in Bit 12 of this word.

Bit 12: OUT1_State_at_Connection_Lost –

When bit 13 of this word is set, Output 1 will be set to the

state of this bit if the network connection is lost.

Bit 11: Read_Present_Configuration –

If this bit is set when you enter Configuration Mode, the Net-

worked Driver responds by placing the present configuration data in the Network Input Data. You
cannot write new configuration data to the unit while this bit is set. The format of the Configuration
Data is given in the

Input Data Format

section of this chapter, starting on page 66.

Bit 10: Save_Present_Configuration –

An AMCI Networked Driver will store its configuration data to

flash memory when this bit makes a 0



1 transition. The validity of the configuration data is checked

before being written. If the data is not correct, the transition on this bit is ignored. If the write to flash
completes successfully, the Networked Driver will write 16#AAAA into the last word of the Network
Input Data and the Status LED will start flashing green. If the write is unsuccessful, the Networked
Driver will write 16#EEEE into the last word of the Network Input Data and the Status LED will start
flashing red. Once the Networked Driver issues its response to the Save_Present_Configuration com-
mand, it stops responding to commands and you must cycle power to the unit. This design decision
prevents the Networked Driver from responding to constant save commands from the host controller.

1) This feature was added to support users whose host controllers have very limited function-

ality. Consider the consequences of using this feature. Adding the code necessary to write
down the configuration to a Networked Drive on power up or network connection is fairly
straight forward on most PLC based hosts. Adding this code allows you to easily change the
configuration in the host and easily configure a new drive if you ever need to swap a drive
out of the machine. Sample code from AMCI includes this functionality.

2) The endurance of the Flash memory is a minimum of 10,000 write cycles.

3) If using the EDS file to configure the Networked Driver, the configuration data should be

entered on the Configuration tab when setting the properties of the driver. This configura-
tion data is written to the driver whenever the network connection is established.
