Chapter 3 Operate the Module
Modes The XM-124 module operates in two modes.
To change the operation mode of the module, use the parameter in the EDS
file. The Stop and Start services can also be used to change the operation mode.
Transition to Program Mode
Parameter values can only be downloaded to the XM-124 module while the
module is in Program mode. Any attempt to download a parameter value while
the module is in Run mode results in a Device State Conflict error.
To transition from Run mode to Program mode on a DeviceNet network, set
the Device Mode parameter to Program mode and click Apply. You cannot
change any other parameter until you have downloaded the Program mode
parameter.
See your DeviceNet documentation for specific instructions on how to edit
EDS device parameters.
Mode Description
Run The XM-124 standard dynamic measurement module collects measurement data and
monitors each measurement device.
The XM-440 establishes I/O connections with the XM® measurement modules in its
scan list and monitors their alarms, and controls its own relay outputs accordingly.
Program The XM-124 module is idle.
The XM-124 measurement modules stop the signal processing/measurement
process, and the status of the alarms is set to the disarm state to prevent a false alert
or danger status.
The XM-440 closes the I/O connections with the XM® measurement modules in its
scan list and stops monitoring their alarms, relays are deactivated unless they are
latched.
Configuration parameters can be read, updated, and downloaded to the XM-124
module.
IMPORTANT The XM Serial software automatically puts the XM-124 module in
Program mode and Run mode without user interaction.
TIP The module status indicator flashes green when the module is in
Program mode.
TIP You can also use the Stop service to transition the module to Program
mode.
