MENU Network

This menu contains all of the information and settings needed to set up a CANopen network. In this menu, the following entries are listed:

• Node No. - Each device in the network must be allocated its own address (node number 1-62)
• Enable - Without network release (OFF / ON), the device cannot send or receive messages; it would thus not be able to take part in communication.
• Autooperat. - If the network only consists of devices from the UVR1611- family (UVR1611, CAN monitor, BL-NET, etc.), autooperat. must be set to yes (normal case). If there is a master or network manager in the network, autooperat. must be set to no.
• Status – Autooperat. is set to yes, the status automatically switches from init → preop(erational) → operat(ional) after the controller is started according to a preset procedure. Only then is communication possible. If there is a bus master, it will switch the nodes to operational.

A total of 16 digital and 16 analogue network outputs can be programmed. All of the input and output statuses, output variables for the functions, network status, sensor status, and the status of messages can be used.

Transmission conditions: This menu determines the conditions for the transmission of output variables.

The transmission conditions are divided into five groups:

• digital network outputs 1-16
• analog network outputs 1-4, 5-8, 9-12, and 13-16

A total of 16 digital and 16 analog network inputs can be programmed. They are indicated by the transmission node number and the number of the network output variable of the transmission node.

Assumption: The analog network output 1 on CAN-node 2 is assigned to outdoor temperature. Transmission thus does not include the unit or a label. Therefore, the reception node only receives the number 234. Only when linked with a function, such as input variable outdoor temperature in the function module HEATING CIRCUIT is the correct value displayed: 23.4°C. When the controller is started, the entire analog network input variables are set to 0 and all of the digital ones to OFF.

Another example: input of the volume flow from the electronic volume flow encoder FTS4-50DL via the data link (DL-Bus). Sensor address = 1.

Timeouts are monitoring functions that can cause reactions in the control strategy, if bus messages are missing (such as a result of a device failure). The timeouts are divided into 8 groups of network inputs:

• Digital network inputs 1-4, 5-8, 9-12 and 13-16
• Analog network outputs 1-4, 5-8, 9-12, and 13-16

As long as the information is being read from the CAN bus, the network status is OFF. If the value has not been updated since the set timeout, the network status changes from OFF to ON. You can then program the system to react to the failure of a network node or a lack of information. The network status can optionally be selected for individual inputs or for all network inputs together („network status 33“).
Network and network status are also available as sources for input variables in all function modules and messages.

In this menu, the parameters for the data logging via a CAN bus connection can be set. The data logging via the CAN bus requires the operating system A3.17.

Programming in TAPPS

CAN data logging is only possible with the Bootloader BL-NET. In contrast to data recording via the DL-bus, the data to be logged via the CAN-bus are freely selectable. Likewise, there is no constant data output. Upon querying of a BL-NET the controller stores the actual values in a logging buffer and locks this to prevent it from being overwritten (requests received from a second BL-NET) until the data are read out and the logging buffer has been released again. In the menu Network/Data Logging the parameters for data logging are defined via a CAN bus connection.

The necessary settings of the Bootloader for data logging via CAN bus are comprehensively described in the manual of the Bootloader BL-NET.

Menu overview:

WARNING! Settings are immediately deleted without prior security prompt!

Master Node – The controller is allocated one BL-NET as the logging master. The logging command of this master has absolute priority; this means that the logging buffer is always updated upon the command of the master (even if it is blocked by another BL-NET) except for when, at this point in time, data is being output (sent) to another Bootloader.

Timeout – The duration of the logging buffer data block has a time limit. Once this time span has expired, the buffer is again released by the controller.

Digital and Analogue Values - Each controller can output a maximum of 26 digital and 32 analogue values using 2 data records that are defined in the menu „Network/Data Logging“ of the UVR 1611.

Delete All Def. – is only displayed at expert level. All settings (definitions) in data logging can be deleted by pressing the scroll wheel once. All logging values are in this respect set to Source: User <unused>.
CAUTION! Settings are immediately deleted without prior security prompt.

When data logging via the DL-bus, there is a constant data flow from the controller to the Bootloader BL-NET or data converter D-LOGG. The values or states of all inputs, switch outputs and the values of up to two heat quantity counters are specified as a data record. For more information see chapter Outputs/Special Features of Output 14.

All network nodes in the network, with which the controller is linked, are listed here. This means that I/O modules and bus converters can be set from the controller. For CAN monitors, the room temperature (and room humidity for respective version) is displayed. Setting CAN monitors and accessing other controllers is not possible.
