Danfoss DST P92C Pressure Transmitter
General Information
General
The pressure transmitter DST P92C measures the physical quantity pressure. The range depends on the sensor which is used in the transmitter and is 25–800 bar. The measured value is transmitted on the CAN-Bus with the J1939 protocol. The transmitter takes 1000 samples per second, does filtering and converts the raw value into the output format.
The CAN 2.0B interface is able to run up to a speed of 1 Mbit/sec with 11-bit and 29-bit identifiers.
CAN Interface
The device includes a Full CAN controller specified to CAN 2.0B. The physical layer of the 2-wire interface is specified according to ISO 11898. The wires are protected against short circuit. By adjusting the rise and fall times of the CAN signals, the noise emission is minimized. The bus termination resistor is not included in the device.

J1939 Communication
Introduction
The Society of Automotive Engineers (SAE) developed the 1939 standard to be the preferred CAN for equipment used in industries ranging from agriculture, construction, and fire/ rescue to forestry, materials handling as well as on and off-highway vehicles. It is a high-level protocol that defines how communication between nodes (modules) occurs on the bus.
The 1939 network is a specific communication system, supporting specific sets of applications and a specific industry, rather than being generalized.
Any electronic control unit (ECU) using J1939 is permitted to transmit a message on the network when the bus is idle. Every message includes a 29-bit identifier, which defines the message priority, what data is contained within the 8-byte data array that follows the identifier, and which ECU sent the message.

Definitions
PGN
The PGN (Parameter Group Number) uniquely identifies the Parameter Group (PG) that is being transmitted in the message. The Parameter Group Number (PGN) is a part of the 29-bit identifier sent with every message.
SPN
Each parameter used in the J1939 network is described by the standard. A Suspect Parameter Number (SPN) is a number that has been assigned by SAE committee to a specific parameter. Each SPN has the following detailed information associated with it: data length (in bytes);
data type; resolution, offset; range; and a tag (label) for reference. SPNs that share common characteristics will be grouped into a Parameter Group (PG) and will be transmitted to the network using the same PGN.
