Status
This page shows some status information about the Modbus interface that is used
for drive connection. The status screen is split into multiple columns and rows.
Transparent Modbus/TCP indicates the Modbus traffic from Modbus/TCP to Modbus
RTU, this functionality is also know as Modbus gateway. Information about
connected devices is indicated with device-specific counters. Clear all counters by
pressing 'clear' button below the Serial Modbus Status window. The Modbus/TCP
messages field shows information about requests that originate from a Modbus/TCP
master attached to SREA-01 and that are redirected by the internal Modbus/TCP
gateway to the drive interface. Other Modbus messages field shows information
about requests that originate from SREA-01, either from internal applications such
as Logging and Alarms, or web pages such as the parameter page.
The values displayed in the Serial Modbus Status display:
Valid Responses - Counts valid responses from the drives.
Serial Timeouts - The number of time-outs from attached drives.
Exceptions - Counts all exception responses from the connected drives.
CRC Errors - The number of checksum errors on incoming Modbus/RTU
responses.
Buffer Overruns - If an incoming Modbus/RTU response is larger than 300 bytes,
this will cause the input buffer to overflow.
Frame Errors - If an incoming Modbus/RTU response has incorrect length or some
other fault in the frame, this will cause a Frame Error.
