Device settings

Basic settings

Input window "Device settings", tab "Basic settings"

1	Buttons for switching between the individual tabs of the input window
2	Time between measurement data recordings
3	Time between transmissions
4	Button to apply the settings Note: To save the settings, the "Save" button below the "Smart Actions" configuration section must also be clicked.

Interfaces

Input window "Device settings", tab "Interfaces"

1	Selection whether the Modbus interface should be active
	Off	Interface deactivated
	On	Interface activated
2	Selection of the required baud rate
3	Selection of the required stop bits
4	Selection of the required parity
5	Number of data bits to be used
6	Time during which the modbus server must react to the command from the device
7	Selection if the commands should be repeated when a communication error occurs
	Off	A communication error is highlighted immediately.
	1-3	When a communication error occurs, the relevant command is repeated x times. The error is only highlighted when the selected number of attempts has failed.
8	Number of measurement cycles for which the measurement value is held until the error value is issued
9	Selection whether the 120 Ω terminating resistor betw. RS485 A and B should be active
	Off	Terminating resistor deactivated
	On	Terminating resistor activated

Important:

Example to explain the correlation between "Response timeout", "Retry" and "Record interval"

Basic settings		Record interval	1 min.
Interfaces	1. attempt	Response timeout	4 sec.
	Retry	Response timeout	4 sec.
		Retry	1

Explanation: 3 channels are activated in this example. However, the Modbus server does not respond. At the time of recording, the system first attempts to read the data for Modbus measurement channel 1. As "Retry" is enabled, once the "Response timeout" has expired, another attempt is made to read the data for Modbus measurement channel 1 from the Modbus server. Once the "Response timeout" has expired again, the error value "OL" (Open Loop) is set for Modbus measurement channel 1 and the first attempt to read the data for Modbus measurement channel 2 is initiated.

Therefore, the number of active Modbus measurement channels, the "Response timeout", the number of "Retries" and the record interval must be set as follows:

Retry not active: "Response timeout" * Number of active channels < "Record interval"

Retry active: "Response timeout" * (1+ number of retries) * Number of active channels < "Record interval"

Sensor supply

Note: Only one sensor supply is available. Therefore, both the voltage level and the duration for which the sensor supply is switched on prior to measurement must be selected so that they are suitable for all sensors used.

Input window "Device settings", tab "Sensor supply"

1	Selection whether the sensor supply should be active
	Off	Sensor supply deactivated
	On	Sensor supply activated
2	Selection of the output voltage for the sensor supply
3	Time for which the sensor supply is switched on prior to measurement
