Edge Server 200/258
14.1.2 Communication with the OT-network
To communicate with the connected OT-network the Edge Server uses,
among other protocols, the protocols SNMP (Simple Network Management
Protocol) and ARP (Address Resolution Protocol). In addition to this,
PROFINET protocols are used for communication with PROFINET devices,
and an IO-Link UDP protocol transmitting encapsulated IO-Link data is
used for communication with IO-Link master devices in the OT-network.
