Configuring the ControlNet Module 4-3
4.4 Setting the I/O Configuration
The I/O configuration determines the type of data sent to the drive.
This is a two-part process: enabling/disabling the data transmitted
betweeen the module and the drive, and identifying the data
transmitted between the module and the scanner.
Step 1. Enable or disable the data transmitted between the
module and the drive by setting the bits in DPI I/O Config
(13). A “1” enables the I/O. A “0” disables the I/O.
Bit 0 is the right-most bit. In figure 4.3, it is highlighted and equals
“1.”
Step 2. If Logic Command/Reference is enabled (default),
configure the parameters in the drive to accept the Logic
Command and Reference from the module. For example,
set Speed Ref A Sel (90) in an SP600 drive to “Network”
so that the drive uses the Reference from the module.
Also, verify that Logic Source Sel (89) is configured to
receive the desired logic from the module.
Step 3. If you enabled one or more Datalinks (optional), configure
parameters in the drive to determine the source and
destination of data in the Datalink(s). Also, ensure that the
ControlNet module is the only module using the enabled
Datalink(s).
Step 4. Reset the module. Refer to section 4.7.3, Resetting the
Module.
The module is ready to receive I/O from the master (i.e., scanner).
You must now configure the scanner to recognize and transmit I/O
to the module. Refer to chapter 5, RSNetWorx Configuration for
PLC-5C Applications, for more information.
