A text entry box is available which allows customization of the device’s name 
for identification on the EtherNet/IP network.  This string is accessible as the 
“product name” attribute of the identity object.  Refer to Figure 35. 
 

 

 

EtherNet/IP clients 
(such as PLCs) have 
the option of adding a 
32-bit “run/idle” 
header to all class 1 
(I/O) data packets 
sent to devices.  Bit 0 
of this header is 
called the “run/idle flag” by the EtherNet/IP specification, and is intended to 
signify when the client is in a “running” state or an “idle” state.  A running state 
(run/idle flag = Run) is indicated whenever the client is performing its normal 
processing (e.g. scanning its ladder logic).  An idle state (run/idle flag = Idle) is 
indicated otherwise.  For example, Allen Bradley ControlLogix PLCs will set 
their run/idle flag to Idle whenever their processor keyswitch is placed in the 
“PROG” position, presumably in preparation to receive a new application 
program from RSLogix. 
 
The behavior of EtherNet/IP devices when they receive I/O data from a 
controller with the run/idle flag set to Idle is not specified in the EtherNet/IP 
specification.  The interface card allows the option of two different behavioral 
responses when a run/idle flag = Idle condition is received, depending on the 
state of the checkbox indicated in Figure 36. 

• 

If the checkbox is cleared (default setting), then the interface card will 
maintain the last I/O data values received from the client.  For example, if 
the inverter was being commanded to run prior to the run/idle flag being set 
to Idle, then it will continue to run. 

• 

If the checkbox is checked, then the interface card will invoke its user-
configured timeout processing (refer to section 10.7.4).  This setting allows 
the user to determine any inverter behavior they may desire (stop the 
inverter, fault the inverter, ramp to a preset speed, etc.)
