4.8 SERIALNUMBER

TheDeviceNetserialnumber(attribute6ofIdentityobject)mustbeuniqueincombinationwiththeVendorid.Inour

implementation this number iscalculated fromtheBronkhorst serial number string (proparprocess 113, parameter

3).



Layoutserialnumberstring:"AB2#####NNP"



Meaning:



AB=year

A= 'M' :year

2000‐2099

B='0'‐'99' :yearmodulo100

2=always'2'(indicatesthatanorderhasbeenreceived)



#####=ordernumberof4or5digits(0000to9999or00000to99999)



NN=optionalcodeof1or2letters(forexample'A',

'B'or'AA'etc)

'A'=0,

'B'=1,

'Z'=25,

'AA'=26,

'AZ'=51,

'IV'=255



P=optionalsequencenumber('0'to'9')



NNandPareoptionalandmaybeomitted;inthatcasetheyareassumedtobe0.

Computation

ofDeviceNetserialnumber(0x01/1/6,UDINT)



TheDeviceNetserialnumberiscomputedasfollows:

 value range bits

(a) (year‐2000) 0‐19 5

(b) ordernumber 0‐52427

(c) sequencenumber 0‐9

(bc) (ordernumber*10)+sequencenumber 0‐524279 19

(d) code 0‐255 8



The DeviceNet serial number is computed by bitwise concatenating of (a), (bc) and (d). This will result in a 32 bits

value.



Note: when theserial number string is not filled in according to the above template, theresulting DeviceNet serial

numberwillnotbeuniqueanymore.
