Communication monitoring
Monitoring of inactive communication channels
• An inactive channel is one that is not currently involved in the control of the drive.
• An alarm on a port or network card does not trigger a communication fault on an inactive channel.
Example:
A drive is equipped with an Ethernet card solely for the purpose of monitoring the drive. If the drive is disconnected from the Ethernet
network, no fault is triggered.
Enabling of inactive communication channels
• An inactive communication channel is enabled once all the monitored parameters assigned to it have been confirmed.
Example:
A drive is in I/O profile with simple speed control. Modbus constitutes both the command and reference channel.
The Modbus channel will be enabled as soon as the control word and speed/frequency reference have been received.
• When switching from an enabled channel to a disabled channel, the drive immediately triggers a communication fault.
Special case involving Modbus TCP/IP Ethernet card
• In the event of an FDR or IP address duplication fault, a communication fault is triggered regardless of the state of this channel (active,
participant, etc.).
