
Operand: this is the Operand Tag address or the constant value
o Type: if Number is selected for Operand Type, select what format type is used.
Options are Unsigned, Signed, Hexadecimal, BCD, or Float (for 32-bit registers)
Write Value to Tag

configuring a global task or a “while showing” screen task Only PLC tags are used.
o Enable: if ON, allows task to be executed
o Done: HMC7000 sets this coil after completion of task

Executing a Task
Tasks activated from the following sources in MAPware-7000:

Quick Button keys- all of the quick button keys (i.e. Go to Screen, Set Bit, Write Value to
Tag, etc.) are, in fact, designed to implement a simple task. For example, the Go to
Screen button key, when pressed, executes the Go to Screen task.

Touchscreen button keys- in addition to the quick button keys, there are two ‘specially
designed’ advanced button keys that can perform multiple tasks: the Multi-Task Single-
State button and the Multi-Task Multi-State button . Note: see Chapter 5 Data
Objects for more information on these buttons.
