2.3 FP-FMU LEDs and Connectors
Various FP Fieldbus Master Units (FMUs) are available to meet your networking needs.
LEDs
Two dual-color LEDs give you a quick overview of the FMU's status at a glance:
•
SYS (for DeviceNET MNS ). Defines the general status of the FMU. For the hardware,
yellow means the self-test has been passed and the firmware loaded. Green is used for
application oriented functions such as valid configuration loaded.
•
COM . Shows communication errors or status and communication activities. See
subsequent sections for details.
