LED Status Indicator
The LED Status indicator labeled MNS (see Figure 1-1) provides information
on the status of operation as shown in Table 2-2. The indicator has five states,
Off, Blinking Green, Steady Green, Blinking Red, and Steady Red.
After connecting the drop cable to the trunk of the active network, observe
the condition of the Status LED. The option unit uses the Combined Module/
Network status LED scheme described in the DeviceNet communications
standard.
