8.11.4.3 Handling of PN, KN and LI, in protocol version PDT
The handling of PN, KN and LI are controlled by the two parameters Barcode scanned and VIN number
type.
Request for TMU
When PowerMACS requests a TMU from the PLUS server the value to use for PN, KN or LI is sampled
from the PLC variable PLUS_BARCODE. If the value shall be treated as a PN, KN or LI is controlled by
Barcode scanned, see table below.
PLUS_BARCODE
is treated as
Sending results
When PowerMACS sends result data to the PLUS server the value to use for PN or KN is sampled from
the Wp ID field in the result. VIN number type controls if Wp ID shall be treated as PN or KN, see also the
table below.
The Wp ID shall always begin with the letters “PN” or “KN” if everything is correct. These letters are
removed before the result is sent to PLUS.
Before the cycle data is sent Wp ID is checked for consistency. If it begins with “PN” and “VIN number
type” is KN or vice versa an event is generated. The same will also happen if the letters “PN” or “KN” is
completely missing or if the length of Wp ID is not correct. If the layout of Wp ID is wrong no data will be
sent to PLUS.
