WebConsole - System Options
42 NI Series WebConsole & Programming Guide
Manage System - System NumberThe options on this page display the current System Number assigned to the target Master (read-only),
and allow you to change the system number (see FIG.28).
Changing the System Number On the Master
1. Enter the new numeric value into the New System Number field.
2. Click the Accept button to save this new value to the system on the target Master.
The message; "System number changed to X. Master must be rebooted for the change to take
effect.", reminds you that the Master must be rebooted before the new settings take effect.
3. Click Reboot to reboot the target Master.
The Device Tree then reads "Rebooting....". After a few seconds, the Device Tree refreshes
with the current system information (including the updated system number assignment).
If the Device Tree does not refresh within a few minutes, press the Refresh button and
reconnect to the Master.
Using Multiple Netlinx Masters
When using more than one Master, each unit must be assigned to a separate System value.
A Master’s System value can be changed but it’s device Address must always be set to zero (00000).
The Device Addressing dialog will not allow you to alter the NetLinx Master address value.
Example: Using an NI-2000 and NI-4100:
The NI-2000 could be assigned to System 1 (with an Address of 00000).
The NI-4100 could be assigned to System 2 (with an Address of 00000).
Manage System - Control/Emulate OptionsClick the Control/Emulate link (in the Manage System tab) to access the Control/Emulate Options page
(FIG.29). The options on this pa ge allow you to Control or Emulate a device connected to this Master.
Device Control/Emulation is accomplished by manipulating a target device’s channels, levels, and
sending both send commands and strings to the device.
To Control a device means that the program generates messages which appear to a specified
device to have come from the Master.
To Emulate a device means that the program generates messages which appear to the Master
to have come from a specified device (physical or virtual). When Emulate is selected, a Push
button is added to the Channel Code section (see FIG.29).
