Supported platforms: CODESYS 2.3, CODESYS 3.5

 

AddressClaiming's Description

This library implements an address claiming procedure that reserves the needed addresses on the bus (network management functionality).

It can be used with ISO 11783 (ISOBUS) and SAE J1939 bus protocols.

 

Public functions

POU

Description

ACL_AddressClaimServer (FB) (CODESYS 2.3)

AddressClaimServer (FB) (CODESYS 3.5)

The main function block of the address claiming.

ACL_SearchMatchingDevice (CODESYS 2.3)

Function is used to search for matching address claim device from server's system devices list

ACL_DeviceToPGN (FB) (CODESYS 2.3)

DeviceToPGN (FB) (CODESYS 3.5)

Function block is used to link address claiming device(s) to J1939 PGN.

 

Limitations

 The following features from ISO standard are NOT implemented:

  • Command configurable address (4.2.5 in ISO 11783-5:2011)

  • NAME management message and procedures (4.4.3 in ISO 11783-5:2011)

  • Address claim server does not save own device addresses to non-volatile memory as new initial addresses (see 4.3.3.4 in ISO 11783-5:2011). It should be handled by application. For ISOBUS see also ISOBUS Conformance Guide.

  • Address violation is not monitored by library (4.4.4.3 in ISO 11783-5:2011).

  • Application would need to implement monitoring of own transmit messages (i.e. receive own tx messages) to detect address violation.
