Possible parameter values are listed in table below.
Monitoring values show the current speed and duplex value. Possible values are listed in table
below.
6.1.6
Communication timeout
It defines how much time can pass from the last received message from the Master Device before
a fieldbus fault is generated. The functionality of this value is protocol-specific.
A fieldbus fault is also generated if the Ethernet link is down for over 60 seconds after the device
startup. The Ethernet link status is being checked until the fieldbus communication is activated.
After that the active fieldbus protocol controls the activation of the fieldbus fault.
The functionality of this value is protocol-specific.
6.1.6.1
Modbus
For Modbus, this value defines a time in which a message must be received (from Client in Modbus
TCP/UDP) before a fieldbus fault is generated. If timeout is set to zero, no fault is created.
See Chapter 7.4 "Modbus communication and connection timeout".
6.1.6.2
Profinet IO and EtherNet/IP
For these protocols, this value is considered as an additional timeout which works on top the
timeout mechanism of the protocol. When a connection loss is noticed, a fault activation is started.
If communication timeout value is zero, the fault is activated immediately, otherwise the fault
activates after a specified time. If the connection is reopened before the specified time has elapsed,
no fault is created.
See Chapter 8.5 "PROFINET IO communications and connection timeout" for more details on how a
timeout is created while using PROFINET IO protocol.
See Chapter 9.1.6 "EtherNet/IP communication and connection timeout" for more details for more
details on how a timeout is created while using EtherNet/IP protocol.
