Chapter 4 Configuring the I/O
When using Datalinks you must still assign Host parameters C161 [Opt
Data In 1] through C164 [Opt Data In 4] and C165 [Opt Data Out 1]
through C168 [Opt Data Out 4] to point to the appropriate drive or
connected peripheral parameters. The procedure to configure the
Datalinks on the Module Definition window for the Input Data and
Output Data is the same:
• Click the button to assign a parameter to each input and output
Datalink you require.
6. Click OK on the Module Definition window to save the drive
configuration and close the window. The drive’s New Module window
reappears.
7. On the New Module window, click the Connection tab.
8. In the “Requested Packet Interval (RPI)” box, set the value to 2.0
milliseconds or greater. This value determines the maximum interval that a
controller should use to move data to and from the adapter. To conserve
bandwidth, use higher values for communicating with low priority devices.
The “Inhibit Module” box, when checked, inhibits the module from
communicating with the RSLogix 5000 or Logix Designer project. When
the “Major Fault On…” box is checked, a major controller fault will occur
when the module’s connection fails while the controller is in the Run
Mode. For this example, leave the “Inhibit Module” and “Major Fault
On…” boxes unchecked.
IMPORTANT Always use the Datalink parameters in consecutive numerical order,
starting with the first parameter. (For example, use parameters C161,
C162, and C163 to configure three Datalinks to write data and/or
parameters C165, C166, C167, and C168 to configure four Datalinks to
read data.) Otherwise, the network I/O connection will be larger than
necessary, which needlessly increases controller response time and
memory usage.
