Note
The total number of sockets used by following protocols (over all Interfaces) must not exceed 32:
- UDP data exchange
- UDP no AC31 Header
- ABB netConfig
- Online with ABB TCP/IP Level 2AC (listen, connected, routing)
- SNTP (onboard only)
- SMTP (onboard only)
- Modbus Client
- Modbus TCP server
Note
For CPUs with multiple Onboard Ethernet interface (e.g. PM591-2ETH, PM595-4ETH) the maximum number of sockets per protocol is the sum for all Ethernet interfaces.
Example: Max number of Modbus TCP server for PM591-2ETH is 24. If 1:sup:st Ethernet interface ETH1 uses 11 Modbus server connections, the 2nd Ethernet interface can use as maximum 13 Modbus server connections.
Note
The usage of the sockets can be shown in PLC browser in CoDeSys and/or in PS501 Control Builder Plus using command: coupler settings
