Several tools and interfaces from different vendors are on the market. For communication structure and
way of commanding with these tools and interfaces you need to consult the vendor.
Operation via DeviceNet
®
is sophisticated and requires specific knowledge and training about it and its
tools.
VAT offers valve-related but not general DeviceNet
®
support. Contact us under: devicenet-
1. The node number is the device address and can be selected by two rotary switches which are on the
valve controller panel. For example, to set the address to 13, set the MSD (most significant digit) to 1
and the LSD (least significant digit) to 3. (Factory default is 00).
Sample picture
In case a valid node number (0-63) is selected the number will be used at start of
system as MAC-Id of the device and stored in the device memory. In this case node
number is not selectable by DeviceNet
®
service.
If an invalid node number is selected (> 63) node number will be read from the device
memory and node number is settable by DeviceNet
®
.
2. The baudrate can be selected by a rotary switch (DATA RATE) which is also on the valve controller
panel.
If a valid baudrate is selected (125kBaud, 250kBaud, 500kBaud), the rate will be used
and stored in the device memory as actual baudrate (Factory default is 500kb). In this
case baudrate is not selectable by DeviceNet
®
service.
If an invalid baudrate is selected, the baudrate will be read from the device memory
and the rate is settable by DeviceNet
®
.
3. DeviceNet
®
offers many parameters that may be set. Many of them are not directly used to operate
the valve but are part of the DeviceNet
®
profile. You may set all parameters via electronic data sheet
(EDS) or via explicit messaging. Setup steps 3 to 5 describe all valve specific parameters that require
a setup to enable for valve operation.
The Electronic Data Sheet (EDS) allows the configuration of DeviceNet
®
components with a general
configuration tool. The EDS contains general data regarding device, selection of operation mode,
assignment of I/O data to the corresponding I/O message connections (Polling, Bit Strobe, Change of
State) and description of device parameters. The parameters of a device are described in a form which is
defined by DeviceNet
®
and visualized by a configuration tool.
EDS can be downloaded on our website: http://www.vatvalve.com/customer-
service/informations-and-downloads/electronic-support-files > EDS Files
4. If Poll or Change of State / Cycling connection is used for remote operation it’s required to preset
the correct assemblies.
Refer to chapter «DeviceNet interface» > «Assembly objects» for default values.
