Table 1 - Technical data
Using the IoT Box, you can integrate weighing data from up to 16 EHP crane scales simultaneously into
your PLC system. Thanks to predefined GSDML & UDT file, a connection can be established in a few
minutes without much effort.
Transmission takes place via Profinet or Modbus TCP as standard, but can also optionally take place
via Modbus RTU or Profibus DP (factory preset according to customer requirements). The weighing
data transmission from the IoT Box is integrated as a slave in the higher-level PLC system.
Once the IoT Box is successfully connected to your PLC system, a wide range of applications are
possible:
In addition to the pure visualization of the measurement data and control of the scales (e.g. tare,
fixtare - specify tare value yourself, set to zero, register weight), you can also receive/send commands
from other PLC participants. Start a measuring process at the push of a button and then have the
weighed goods transported away, or transfer the measured data directly to your ERP / CRM system in
order to obtain an evaluation of material usage and to document warehouse consumption. The
possibilities are almost limitless.
● IoT Box
The following accessories are included as standard:
● Connector for power connection - Neutrik Powercon NAC3FCA
● Connector for network connection - Neutrik Ethercon NE8MX
● Angle antenna
