DeviceNet Installation
•
Download the DeviceNet VP51 EDS file from www.odva.org
• Register the EDS file using a DeviceNet configuration tool (e.g. Rockwell RSNetworx).
• The device MACID and baud rate are factory set to address 63 and Autobaud (see notes 1 & 2).
• Connect the DeviceNet VP51 to a DeviceNet network.
• Use the keypad or your DeviceNet configuration tool to change the MACID and baud rate parameters as
required.
• Map the polled i/o to a DeviceNet master device (e.g. PLC scanner).
• Control the pressure by polling the polled input ‘Demand Pressure’ over the range 0-4095 (=0-105% of
output pressure range).
• Use a DeviceNet configuration tool (e.g. Rockwell RSNetworx) to change the DeviceNet VP51 parameters
to suit the application (see note 3).
Notes:
1) MACID - The DeviceNet VP51 MACID is factory set to 63. Once the DeviceNet VP51 is powered, this
can be changed either over the DeviceNet network or using the instrument’s keypad. If the DeviceNet
VP51 detects that another device on the network already has its MACID, it will display a “Set Node
Address” message instructing you to change the its MACID using the keypad. See section 7 of this
manual for more details.
2) Baud rate - The DeviceNet VP51 is factory set with Autobaud detection. This means that it ‘listens’ to
the network, detects the baud rate and selects its own baud rate accordingly. In order for this to work, it
is necessary for the DeviceNet network to already have two or more other devices actively
communicating on the network. After successful Autobaud detection, the baud rate parameter
automatically switches to the selected baud rate. To run the Autobaud function again, the baud rate
setting must be changed back to Autobaud via the keypad or DeviceNet. If Autobaud detection is
unsuccessful or if the instrument has previously been set to an incorrect baud rate, it will automatically
display a “Set Baud Rate” message instructing you to change the baud rate using the keypad. See
section 7 of this manual for more details.
3) ADR facility - The DeviceNet VP51 supports ADR (Automatic Device Recovery). If the PLC has been
configured to provide this feature and a DeviceNet VP51 is replaced with a new one, the PLC will
automatically detect the new one and configure its address and parameters to be the same as the
device it is replacing. Refer to the PLC and DeviceNet configuration tool instructions for more details.
