Appendix C Quickstarts
In many cases, the front of the controller is not visible to the operator and the
Connected Components Workbench software is not online with the controller.
If you want the force status to be visible to the operator, then the User Program
must read the force status using the SYS_INFO function block and then
display the force status on something that the operator can see, such as the
human machine interface (HMI), or stack light. Figure 24
is an example
program in Structured Text.
Figure 24 - Structured Text Example Program
If the front of the controller is visible, and not blocked by the cabinet enclosure,
Micro830, Micro850, and Micro870 controllers have a Force LED indicator.
I/O Forces After a Power Cycle
After a controller is power cycled, all I/O forces are cleared from memory.
Use Run Mode Change Run Mode Change allows the user to make small changes to the logic of a
running project and immediately testing it out on the controller, without
having to go into Program mode or disconnecting from the controller.
The following sample project guides you through the creation of a simple
application for a Micro850 controller without any plug-in modules, and how to
use the Run Mode Change feature.
IMPORTANT
The following requirements must be met to use Run Mode Change:
• Micro820/Micro830/Micro850 controller firmware revision 8 or higher, and
• Connected Components Workbench Developer Edition software, version 8 or
higher.
