The DVR
®
2000E+ also has a timeout feature defined by the timeout message time. This feature is disabled if the
timeout time is set to 0 seconds. For any other value of timeout time, the DVR
®
2000E+ will enunciate a Loss of
Communication alarm (Alarm Code A006) unless any ECU delivers a VR Heartbeat message to the DVR
®
2000E+
within the prescribed timeout time. This alarm is latched until the regulator receives a VR Heartbeat message.
The DVR
®
2000E+ message set is defined in the following tables. For each message, the message ID is the
hexadecimal value of the PDU Format and PDU Specific fields combined. Since the DVR
®
2000E+ uses PDU2
format, the first two bytes of all of the identifiers are 0xFF. The message group field identifies which group an
outbound message belongs to for purposes of its priority and transmission rate. The source field identifies
messages coming from the DVR
®
2000E+ (outbound) or to the regulator from an ECU (inbound).
Data byte 0 is the first data byte after the message identifier and data byte 7 is the last data byte. For bit fields
within these data bytes, bit 7 is the most significant bit (leftmost) within a byte and bit 0 is the least significant bit
(rightmost) within a byte. Unless otherwise specified, all values are unsigned bytes. For values containing a Least
Significant Byte (LSB) and a Most Significant Byte (MSB), the result is an unsigned 16-bit word composed of the
two bytes unless otherwise stated.
