XPL J6 NET Indicator: CANopen RUN and ERR States
The XPL NET indicator color/blink codes comply with CAN Indicator Specification CiA 303-3 as
shown below. Green is the RUN state and red is the ERR state. Note that green and red codes
alternate, each indicating a different set of conditions. The green RUN led indicates the state of the
CANopen state machine (pre-operational, operational, or stopped). The red ERR led indicates the
status of the physical layer (warning or error conditions). In addition, the XPL NET indicator is
turned off when the CAN node ID selector (CAN ADDR) is set to 0. A setting of 0, which is invalid,
shuts down most operations on the CAN interface, and the light is shut off to indicate this status.
