Can I connect my existing EHP scales to the IoT Box?
EHP scales that already have the corresponding radio equipment can be connected directly to
the IoT box. If your EHP scales do not yet have radio equipment, this can be retrofitted at low
cost. If your scales are equipped with the appropriate radio technology, they can be connected
to the IoT box without any problems. Otherwise, retrofitting on the part of EHP is also possible
and cost-effective in most cases.
•
How many scales can communicate with one IoT Box?
Up to 16 scales can interact with one IoT box. Older EHP scales can also be easily converted
to communicate with the IoT Box. The EHP crane scale must have a release version LAH12.26
or LAH12.42 to operate with IoT-Box.As standard only scales are integrated which are
purchased together with the IoT-Box. For the integration of existing scales please contact
your EHP contact person.
•
Up to 16 scales can communicate with an IoT Box - is the data acquisition of the scales
always active or only when they are directly addressed? Can individual scales be
deactivated?
By default, all connected scales are always active, this can also be changed if necessary.
•
What protocol types are available?
Profinet or Modbus TCP are the standard protocol types, protocol format is preset
accordingly by EHP. Further possible protocol types are Modbus RTU or Profibus DP. These
are optionally available.
•
What scale functions are available?
Tare, pre-tare (tare with preset value), set to zero, register weight.
•
Does the IoT Box have additional inputs and outputs?
For most applications, no additional inputs and outputs are required on the IoT Box. On
customer request the IoT-Box can be extended with eight digital inputs and six digital
outputs. Analog inputs/outputs are also possible, please contact us!
•
Can I integrate my existing scales?
By default, the IoT-Box is set to operate with newly sold scales. The EHP crane scales must
have a release version LAH12.26 or LAH12.42 to operate with the IoT-Box. If you want to
integrate existing scales, please contact your EHP representative.
