HFV 8000 Generator
CONTROL PANEL ROTARY SWITCHES
The DeviceNet control panel features three rotary switches to set the network address
and communication data rate. Each time the DeviceNet interface is energized the
switch settings are read by the DeviceNet master. Figure 4-13 provides an illustration
of these switches.
Data Rate Rotary Switch
Use the
DATA RATE
switch to select a communication baud rate:
• 0 = 125 kbits per second
• 1 = 250 kbits per second
• 2 = 500 kbits per second
The default is 500 kbits/s. A switch setting in the
PGM
region allows the DeviceNet
master to set the baud rate for the unit.
Note:
If your power supply is configured with two DeviceNet cards, it is important
that you set the
DATA RATE
for
both
cards to the same setting as the
DeviceNet network setting. Any card not set to the network setting will fault
when the network is brought up.
Node Address Rotary Switches
Use the
NODE ADDRESS
rotary switches,
MSD
(most significant digit) and
LSD
(least significant digit), to select the DeviceNet network address (MAC ID). MAC IDs
0 through 63 are valid. Use the
MSD
switch to select the MAC ID’s most significant
digit; use the
LSD
switch to select the MAC ID’s least significant digit. Switch
settings greater than 63 (or in the
PGM
region of the
MSD
switch) allow you to set
the MAC ID through the DeviceNet master.
If your power supply is configured with two DeviceNet cards, it is important that you
set the combined NODE ADDRESS of the first card to a different setting than the
combined NODE ADDRESS of the second card. If you fail to do this, one side will
fault when the network is brought up.
DeviceNet™ Interface Information and Supported Features
The Advanced Energy HFV generator operates as a GROUP 2 slave device on a
DeviceNet network. The unit supports explicit messages and polled I/O messages of
the predefined master/slave connection set. The Advanced Energy DeviceNet
interface does
not
support the explicit unconnected message manager (UCMM).
The DeviceNet interface responds to poll requests in less than one millisecond (<1 ms
poll response time). Explicit requests are serviced in under two millisecond (<2 ms
explicit response time).
