Test procedures for ISOBUS DLG testing

2nd ISOBUS workshop BrazilFebruary 22nd 2008

ISOBUS test

What it is: The official test of a component (software + hardware) for compliance to

the latest ISOBUS implementation level

Result: Certificate ISOBUS 20xx conform Added to www.isobus.net

Idea behind: Only compliant components make ISOBUS work in practice No free use of the term ISOBUS compatible

ISOBUS test

Advantage for the manufacterer Commercial: Customer confidence + marketing argument Legal/Safety: all possible measures taken to ensure proper functioning Service:chances of failure limited to minimum

Organization today

Initiative of VDMA (German federation of manufacterers) AEM (US federation of manufacterers) IGI, NAIITF (user groups)

Done by independent testing institute DLG (German agricultural association)

Hints for developers

Have VTs and components available for developers Use of mask generator tool that usually produces correct code Electronics components: reuse, so no big issue (TBC, connectors,

cables Others terminals / ECUs In house use of P-convert: buy at DLG Plugfests Finish software prior to testing: new software = new testing procedure

Costs

Testing ECU, TECU ~ EUR 5200 VT ~ EUR 6200 Advice ~ EUR 1200 - 1800(EUR 100 /hour + 1200 initial)

Minor changes to certified product cost less

Other services 3-day Training by DLG EUR 3000

ISOBUS, PConvert Pconvert (per year) EUR 600 (?)
