Run Mode
Right after the project has been sent to the CPU, the application will not be performed immediately
(only if an online change has been made). For that to happen, select the “Start” command. This
function allows the user to control the execution of the application sent to the CPU. Furthermore, it
allows initial values to be pre-configured, so they can be updated on the first cycle in the CPU.
To select such functionality, access “Debug” and click “Start”, as shown in Figure 5-38.
Figure 5-38. Starting the Application
Figure 5-39 shows the application running. In case the POU tab is selected, the created variables are
listed on a monitoring window, in which the values can be forced and visualized by the user. In case
the variables are forced through the F7 command on the keyboard, the CPU will indicate this
condition on the graphic display. For further details, see Maintenance – Graphic Display.
When using the protocols MODBUS RTU Slave / MODBUS Ethernet Server, and not selecting the
“Read-only” option, make sure to click “Force Values” (
F7
). “Unforce values” (
CTRL + F7
) allows the
variables to be overwritten when new readings are done.
