4 2 General The pressure transmitter M01-CAN is measuring the physical quantity pressure. The range depends on the sensor which is used in the transmitter and is bar. The measured value is transmitted on the CAN-Bus with the protocol. The transmitter takes 1000 samples per second, does filtering and converts the raw value into the output format. The CAN2.0B interface is able to run up to a speed of 1 Mbit/sec with -bit und 29- bit identifiers. 3 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 898. The wires are protected against short-circuit. By adjusting the rise and fall times of the CAN signals the noise emission is minimized. A bus termination resistor is not included in the device. 4 M01-CAN Specification 4.1 Supply Voltage +U S Supply voltage: Current consumption at U S = 24 VDC: 9 36 VDC, protected against reverse polarity I < 50 ma typical, IMAX < 100 ma 4.2 CAN Interface Physical layer: Bitrate: 2-wire interface, 5 V level according to ISO 898 Protected against short-circuit 250 kbit/sec Signal rise time: Bitrate < 125 Kbit/sec 12 V/µsec (without bus) Bitrate 125 Kbit/sec >24 V/µsec (without bus) Bus termination: Protocol: external SAE Created: , M.

PIN Assignment 1 CAN shield, PE 5 2 +U B, +24VDC GND, 0V 4 CAN_H, CAN+ 5 CAN_L, CAN Communication 5.1 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 offhighway 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 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.

The Parameter Group Number (PGN) is a part of the 29-bit identifier sent with every message SPN Each parameter used in the 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. Created: , M. Breuer Revision date: , A.
