Figure 151: User-configurable communication logic operands window
The left side of this screen displays all operands that are currently available to the D90
The communication logic operands are displayed by selecting the Comms tree item. Each

automation logic, in settings that take operands as their value, and in event reports.
The following communication logic operands are available for the D90
alphabetically by operand syntax The definitions listed below reflect the default operand
names. If desired, these operands can be assigned user-defined names through the
