Update Frequency
This menu can be used to change the update frequency of the
signal. This means the frequency with which requests are sent to
the remote MODBUS unit for either reading or writing the signal
value. When the frequency is set to 0, then modbus requests are
initiated on demand using a modbus_get_signal_status ,
modbus_set_output_register , and modbus_set_output_signal
script functions.
Slave Address
This text field can be used to set a specific slave address for the
requests corresponding to a specific signal. The value must be in
the range 0-255 both included, and the default is 255. If you
change this value, it is recommended to consult the manual of
the remote MODBUS device to verify its functionality when
changing slave address.
Reconnect count
Number of times TCP connection was closed, and connected
again.
Connection status TCP connection status.
Response time [ms]
Time between modbus request sent, and response received -
this is updated only when communication is active.
Modbus packet errors
Number of received packets that contained errors (i.e. invalid
length, missing data, TCP socket error).
Timeouts
Number of modbus requests that didn’t get response.
Requests failed
Number of packets that could not be sent due to invalid socket
status.
Actual freq.
The average frequency of client (master) signal status updates.
This value is recalculated each time the signal receives a
response from the server (or slave).
All counters count up to 65535, and then wrap back to 0.
