Types of Action Blocks
nanoNavigator has four types of action blocks: Control, Message, Move, and Wait. Control
blocks (see Figure 2-6) initiate an action such as turning on an output or resetting a timer.
One Control block can have up to four control expressions. Control expressions set values
for flags, turn outputs on and off, and control timers and counters.
Figure 2-6 Action blocks
Message blocks select a message number (from 0 to 31) to display on the Operator Panel.
The Message Editor (see “Using the Message Editor” on page 3-28) specifies messages to
display.
Move blocks simply move data from one data item to another. The source data item remains
unchanged, and the Wait block inserts a wait period in the execution of the flow chart. A Wait
block can have a wait period set in milliseconds or hours, minutes, and seconds. If the wait
duration is zero, the block defaults to one scan cycle.
