EMERGENCY MESSAGES
Emergency messages are the second highest priority in CANopen and the highest priority that an
ancillary (like the 1353) can transmit. ese messages are sent sporadically whenever there is a
change of state in the 1353’s fault ags.
To prevent fast-changing fault bits from ooding the bus, a minimum Emergency Rate between
messages can be programmed by Curtis programmer or SDO.
An Emergency Message consists of 8 data bytes.
Data bytes 1 and 2 dene the error category.
Data byte 3 is the CANopen-required error register. Curtis products dene this as 0x01 if there is a
fault present and 0x00 when this fault is clear.
Data bytes 4 through 8 dene the specic fault. e 1353 will place the current 24-bit hour meter
into data bytes 4 through 6.
Bytes 7 and 8 are not used by the 1353 and are always 0x0000.
e emergency message format indicating an error is shown below.

HEARTBEAT
e heartbeat message is a very low priority message, periodically sent by each ancillary device on
the bus. e heartbeat message has a single byte of data and requires no response. Once the 1353 is
in the Pre-Operational state, the next heartbeat will be issued and will continue until communication
is stopped.
e heartbeat message has only one data byte. e top bit is reserved and should be set to zero. e
bottom 7 bits hold the current NMT device state.
