Controller Configuration and Modes of Operation Chapter 13
You can set these switches.
This switch Specifies Default
Main Enable whether CPU switches can be changed while the controller is executing.
If Main Enable is disabled, you cannot change the settings of the other 7 switches
(described below) while the controller is in operation (routine in Run).
On/Enabled
Autostart whether the controller automatically starts up after restarting the controller or applying
power to the controller.
If Autostart Enable is enabled, the routine automatically starts up after a restart or
applying power to the controller.
Off/Disabled
Start/Restart allowed whether you can start a routine manually.
If Start/Restart allowed is enabled, you can start a routine manually via the Routine menu
of the Control Panel. Choose either Coldstart or Warmstart. Coldstart is the recommended
setting.
If Start/Restart allowed is disabled, you cannot start a routine manually. You can only start
a routine by restarting the controller or applying power to the controller.
On/Enabled
Loading allowed whether you can load new configuration information to the controller.
If Loading allowed is disabled, no (new) configuration can be loaded into the controller.
This prevents a user from overwriting the current routine.
On/Enabled
Test Mode allowed whether you can freeze the routine.
If Test Mode allowed is enabled, the routine currently running on the controller can be
frozen. This allows the Test Mode with Single Cycle function. You are not allowed to
freeze a routine in standard operation (this would be non-safe operation).
Off/Disabled
Online Test allowed whether you can monitor the Function Block code online. Off/Disabled
Forcing allowed whether you can force signals.
If Forcing allowed is enabled, you can force the signals in the controller.
If Forcing allowed is disabled, you can still display the force editor, but the forcing
functions are locked.
Off/Disabled
Stop on Force Timeout whether to stop forcing when the force time expires.
If Stop on Force Timeout is enabled, the controller terminates execution of the routine
after the user-set force time expires. All outputs go to LOW.
If Stop on Force Timeout is disabled, the controller continues executing the routine with
the process values when the force time expires.
On/Enabled
Max Communication
Time Slice the time in milliseconds reserved for a controller to carry out and complete all
communication tasks in one CPU cycle. This setting is required for Peer-to-Peer
networking. 10 ms
