System Requirements

Field devices 3 max. connected

Variables 100 recommended at 100 ms

Sampling interval 100 ms validated minimum

Higher variable counts or shorter sampling intervals may be possible depending on network conditions and device load, but are not validated.

Network ports

The following ports must be open between the Edge and the respective field devices:

Connector	Protocol	Port
Siemens SIMATIC (S7)	TCP	102
Modbus TCP	TCP	502
OPC UA	TCP	4840 default; configurable
MQTT	TCP	1883 / 8883 (TLS)

Note

On networks with a real-time bus (e.g. PROFINET), Edge data packets are handled with low priority and may be delayed relative to real-time traffic. This can affect the accuracy of the configured sampling intervals.
