44 Configuring Control Options
Note: If you are using a custom shunt resistor, select Custom Shunt and
contact the manufacturer of the custom shunt resistor for the
necessary data parameter settings (D132 to D136). Once these
settings are obtained, use a series of Control Settings blocks to set
these data parameters in your program.
Setting Optional Configurations
Use the information in this section to define additional configurations.
This section provides step-by-step procedures to configure the following:
• An RIO interface
• A CNET interface
Common Bus Enable Select this if this Smart Power 1394 system module
operates as a slave and is connected to another Smart
Power 1394 system module (using DCLink hardware). In
this configuration, one of the two system modules (the
master) supplies DC power to another system module
(the slave) over a common bus. Selecting this sets Data
Bit #63 to 1.
Note:
Select Common Bus Enable only if this
system is the Slave Module. Do not select it,
if this module is the master system module.
Important: To use the Common Bus Enable feature, you must first select Shunt
Resistor.
AC/AC Mode If Common Bus Enable is selected for this slave module,
select AC/AC mode to configure this slave system
module to receive 380/460-volt 3-phase direct AC
power. Selecting this sets Data Bit #64 to 0.
AC/DC Mode If Common Bus Enable is selected for this slave system
module, select AC/DC mode to configure this slave
system module to use only DC power. Selecting this
sets Data Bit #64 to 1. In this configuration, this slave
system module can not use 380/460-volt 3-phase direct
AC power.
