July 30 2009 Page 8 of 23 ECN 985 0913 01 2 2 XL J1939 can request and monitor data from and transmit data to devices on the J1939 network There are two communication methods used for handling data e Receive In which Parameter Group Numbers PGNs are loaded into up to 15 receive tables and the module continuousiv gathers data for the configured PGNs e Transmit In which up to 15 transmit tables are configured to send a message every X number of milliseconds or on trigger The following sections cover each communication method in detail XL J1939 works on consumer and producer concept NOTE A PGN Parameter Group Number is a unique numeric identifier that is associated with a specific parameter name For this number a 16 bit value is used that is composed of the PDU format PF and PDU specific PS It is used to identify a message s function and associated data i e a PGN defines the parameter value that a device is requesting or the parameter value that a device is sending 2 1 Receive The Receiving method uses a scan table that contains a series of PGNs and associated information Data for the configured PGNs is continuously gathered and sent to the PLC There are two modes for gathering data from devices on the XL J1939 network e Monitor Mode e Request Mode Each PGN in the scan table must be configured to use one of the two modes for gathering data NOTE T2. 7 1 3 Technical Specifications ssa 7 t4 a a a a 8 1 4 1 ALJ TIST un a a aa 8 CHAPTER 2 OPERATION a ad G an 9 2 1 FRECEIV 9 2 1 1 Monitor Modests anaiarena A TA pt Tat 9 2 1 2 Re uest Modena 9 10 2 2 1 Timed Transmit Mode 10 2 2 2 Aigger Transmit MOA 1 ia IE Ea 10 CHAPTER 3 CONFIGURATION ahead 11 3 1 Example Configuration and details of individual fields 222 15 3 2 Status Register rara 18 CHAPTER 4 TECHNICAL SUPPORT 32 21 1 15 A E A E 22 TABLE OF FIGUR E S i a aeaaea EEE 23 July 30 2009 Page 5 of 23 ECN 985 TABLE OF CONTENTS MANO913 01 NOTES Julv 30 2009 Page 6 of 23 ECN 985 0913 01 1 CHAPTER 1 INTRODUCTION 1 1 Overview The XL J1939 comes from the international Society of Automotive Engineers SAE and works on the physical layer with CAN high speed according to ISO11898 SAE J1939 defines five layers in the 7 layer OSI network model and this includes the CAN 2 0b specification The application focus is on the power trains and chassis of commercial vehicles It is used in heavy vehicl
