LEGAL FOR TRADE OPTIONS

14.1

Principles

The legal for trade options are a set of functions and indicators that are generally used in weighing applications. They
have an impact on the device behavior regarding the metrological requirements and track every configuration change
that may affect the measurement determination.

14.2

Settings description

14.2.1

Legal for trade switch

This setting activates (

b

0

bit set to 1

) or deactivates (

b

0

bit set to 0

) criteria and parameters related to the use of

eNod4

in OIML compliance.

The

‘legal for trade’

option activation leads to the following changes:

•

the

‘legal for trade counter’

is incremented every time a storage into EEPROM is requested if one or several

metrological settings have been modified.

•

a new

‘legal for trade checksum’

value is calculated every time a storage into EEPROM is requested if one

or several metrological settings have been modified.

•

taring is now impossible if gross measurement is negative.

•

the measurement value variations cannot be read during the 15 seconds that follow the device reset (error
frame in Modbus RTU, value set to -1 in CANopen® and in Profibus DP) and during zero and tare
acquisitions

14.2.2

Legal for trade software version

This RO value identifies the version of the part of the software that is dedicated to the metrology and the
measurement exploitation.

14.2.3

Legal for trade counter

If the

‘legal for trade’

option is enabled, the legal for trade counter is incremented every time a backup into EEPROM

is requested if at least one (or several) of these settings has been modified:

•

legal for trade switch

•

stability criterion

•

decimal point position

•

maximum capacity

•

number of calibration segments
