Advanced Options
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.
