Program Execution in Micro800
Configure and Program
Your Micro810 Controller The Micro810 controller can be configured by either:
• using Smart Relay function blocks using the 2080-LCD display (and
without the use of Connected Components Workbench programming
software), or
• programmed as a full feature microcontroller using Connected
Components Workbench.
You cannot use both the Smart Relay function blocks and also download a
Connected Components Workbench program. You must choose one of the two
methods. Smart Relay function blocks are targeted to simple applications such as
a timer relay for lighting. Downloading a program using Connected Components
Workbench overwrites the Smart Relay function blocks. Conversely, configuring
the Smart Relay function blocks overwrites any Connected Components
Workbench program.
For instructions on how to use Smart Relay functionality, see Use the Micro810
Smart Relay Functionality on page 66 . For quickstart instructions on how to use
the Connected Components Workbench, see the following publications:
• Micro800 and Connected Components Workbench Application Guide,
publication 2080-QR001
• Micro800 and Connected Components Workbench Getting Started
Guide, publication 2080-QR002
For program execution on Connected Components Workbench, see the next
sections.
Overview of Program
Execution A Micro800 cycle or scan consists of reading inputs, executing programs in
sequential order, updating outputs and performing communications
housekeeping.
Program names must begin with a letter or underscore, followed by up to 127
letters, digits or single underscores. Use programming languages such as ladder
logic, function block diagrams and structured text.
Up to 256 programs may be included in a project, depending on available
controller memory. By default, the programs are cyclic (executed once per cycle or
scan). As each new program is added to a project, it is assigned the next
consecutive order number. When you start up the Project Organizer in
Connected Components Workbench, it displays the program icons based on this
