Chapter 4 Configuring the I/O
On the Module Definition dialog box, notice that the automatically-
assigned controller tags DriveStatus, Feedback, LogicCommand, and
Reference are always used.
However, when using Datalinks you must still assign
Host Parameters
01…16 - [DL From Net 01-16] and
Host Parameters 17…32 - [DL To
Net 01-16] to point to the appropriate drive or connected peripheral
parameters. The procedure to configure the Datalinks on the Module
Definition dialog box for the Input Data and Output Data is the same.
a. Click the button in the topmost blank row to display the
Parameter Properties dialog box for the corresponding Datalink.
Data Format Parameters. When the Connection field is set to ‘Parameters via Datalinks’, ‘Parameters’
is automatically selected. When the Connection field is set to ‘Datalinks’, you must select
the number of Datalinks required for your application in the ‘Data Format’ field.
Input Data Assigns selected drive or connected peripheral parameters to be READ by the controller
using DL To Net Datalinks. See steps 6a through 6e below for details.
Output Data Assigns selected drive or connected peripheral parameters to be WRITTEN by the
controller using DL From Net Datalinks. See steps 6a through 6e below for details.
Use Network
Reference Conveniently selects the speed reference for the drive to come from the network. This box
is checked by default.
IMPORTANT Always use the Datalink parameters in consecutive numerical order,
starting with the first parameter. (For example, use Parameters 01, 02,
and 03 to configure three Datalinks to write data and/or Parameters
17, 18, 19, 20, and 21 to configure five Datalinks to read data.)
Otherwise, the network I/O connection will be larger than necessary,
which needlessly increases controller response time and memory
usage.
