The NI 9144 is in safe-operational (SAFE-OP) run
mode. The NI 9144 inputs are functional and outputs
drive constant safe values.
Solid The NI 9144 is in operational run mode. The NI 9144
inputs and outputs are functional.

Table 3. ERR LED Indicators
LED Color LED Pattern Indication
Red Off There is no error.
Continuously blinks There is an invalid configuration from an unsupported
module, bad device profile, object dictionary, or
configuration.
Blinks once and pauses There is an unsolicited change and the NI 9144 or
module is in an emergency condition.
Blinks twice and
pauses
There is an application watchdog timeout. The slave
did not receive a scheduled EtherCAT telegram.
Solid There is a Process Data Interface (PDI) watchdog
timeout. The slave failed to transfer I/O data in
scheduled time.
Flickering There is a booting error from corrupt firmware or a
hardware error.
Safe-State Outputs
The NI 9144 has an EtherCAT safe state that the device passes through when moving from
LabVIEW Active Mode to LabVIEW Configuration Mode. The NI 9144 passes through the
EtherCAT safe state during normal operation or in case of a serious error.
4| ni.com | NI 9144 User Manual
In the EtherCAT safe state, output modules are set to pre-defined safe values. By default, zero
is the safe value in the output module channel configuration. You can change the safe values
by writing to the appropriate object dictionary entries for your output module.
Slave Timing Modes
The NI 9144 operates in free-run mode or synchronized mode using the EtherCAT distributed
clock (DC).
By default, free-run mode runs the conversion cycle at the rate of the slowest module. You can
slow the free-run mode conversion cycle down by writing a minimum cycle time in
nanoseconds to index 0x3001.1 of the NI 9144.
In synchronized mode, each conversion cycle begins with a signal from the EtherCAT master/
scan engine. The NI 9144 procedures an error if the external cycle time is too fast for a
module. NI Indcom for EtherCAT only supports synchronized mode.
Mounting the Device
To obtain the maximum allowable ambient temperature of 70 °C, you must mount the NI 9144
horizontally on a flat, metallic, vertical surface such as a panel or wall. You can mount the
NI 9144 directly to the surface or use the NI Panel Mounting Kit. The following figure shows
the NI 9144 mounted horizontally.

1. Up
You can also mount the NI 9144 in other orientations, on a nonmetallic surface, on a 35-mm
DIN rail, on a desktop, or in a rack. Mounting the NI 9144 in these or other configurations can
reduce the maximum allowable ambient temperature and can affect the typical accuracy of
modules in the NI 9144. For more information about typical accuracy specifications for
C Series modules and temperature deratings caused by different mounting configurations, visit
ni.com/info and enter the Info Code criotypical.
Caution Make sure that no C Series modules are in the NI 9144 before mounting
it.

Tip Before using any of these mounting methods, record the serial number from
the back of the NI 9144 so that you can identify the NI 9144 in MAX. You will be
unable to read the serial number after you mount the NI 9144.

Allow the appropriate space in front of C Series modules for cabling clearance, as shown in
the following figure. The different connector types on C Series modules require different
cabling clearances. For a complete list of cabling clearances for C Series modules, visit
