Time-triggered Variable Page

Requires: RT Module

From the network tree of the Network Configuration dialog box, click a time-triggered shared variable under an RT target to display the Time-triggered Variable page.

Use the Time-triggered Variable page to configure settings for a time-triggered variable.

This page includes the following components:

• SMB Variable—Specifies whether the time-triggered variable is a dedicated slot variable or shared memory block variable. Place a check in the checkbox to make the variable a shared memory block variable. Remove the check from the checkbox to make the variable a dedicated slot variable.
  
  The shared memory block variables of a target node transmit their data as a collection during a section of time in the network cycle. Dedicated slot variables transmit their data individually during a section of time in the network cycle.
• Offset (us)—Available if the variable is a dedicated slot variable. Specifies the time when the variable begins to transmit data during the network cycle.
• Max Size (bytes)—Displays the maximum size of the variable data.
• Transmission Time (us)—Displays a calculation of the amount of time required to transmit the data for the variable during a network cycle.
