Modbus TCP
The Modbus TCP interface is optional, and cannot be ordered with other optional interfaces. It is
used to connect the device to higher-order systems to transmit all measured values and process
values. The Modbus TCP interface is physically identical to the Ethernet interface.
Modbus RTU
The Modbus RTU (RS-485) interface is optional, and cannot be ordered with other optional
interfaces.
It is galvanically isolated (testing voltage: 500 V) and used to connect the device to higher-order
systems to transmit all measured values and process values. It is connected via a 3-pin plug-in
terminal.

Performance characteristic
Reference operating
conditions
• Power supply 230 V AC ± 10%; 50 Hz ± 0.5 Hz
• Warm-up time > 2 h
• Ambient temperature 25 °C ± 5 K (77 °F ± 9 °F)
• Humidity 39% ± 10% RH
Arithmetic unit
The system has a calculation cycle of 125 ms. The amount of medium that flows in the specified
reaction times is reliably measured by the Batch Controller but can deviate by this amount from the
preset fill quantity. Using the after-run correction function or reducing the flow for 1-stage batching
increases the accuracy of the quantity transferred. The use of two batching stages allows for batching
that is both fast and precise.
