Message Block
When configured with the optional Operator Panel, the nanoLC can display messages to
the user. Messages can contain static text, dynamic values from any data item, and data
entry requests. Double-click the Message block to edit its expression. This displays the
Configuration page of the “Message Block” dialog box (see Figure 4-7).
Figure 4-7
“Message Block... Configuration” tab
The drop-down list at the top of the page permits selection of a message number (from 0 to
31). The Message Editor permits entry or modification of the message associated with that
Obtaining User Input
As defined in “Inserting Data Entry Items” on page 3-29, messages can include data
variables that prompt for user input. As the operator enters data through the keypad on the
Operator Panel, the Operator Panel processor validates the input data according to the data
type specified. Once the operator completes data entry and presses the “OK” key, the
Operator Panel passes the input to the flow chart and sets the “Message Input Ready” key
for one scan cycle.
Flow charts that require operator input must continue to look for the “Message Input Ready”
key or some overriding condition that would inhibit data from being entered on every scan
after sending the message requesting input.

Move Block
The Move block simply moves data from one location to another. Doing a move from one
data item to another simply moves (copies) the data of the first data item into the second
data item. The value of the first data item is preserved.
