* Upper-level and lower-level system controllers
The controller described in this manual can only be used as the upper-level controller, but not as a lower-level controller.
• Upper-level system controller (upper-level SC)
Upper-level SC refers to a controller that controls all other system controllers including the units they control.
If a given system has only one system controller, that controller becomes an upper-level controller.
Group settings and interlock settings can only be made from an upper-level controller.
• Lower-level system controller (lower-level SC)
Lower-level controller refers to a system controller that is controlled (including the units it controls) by an upper-level system controller.
NOTE:
The following group setting cannot be performed.
Unit groups which are not under the management of the main controller and are managed by the sub system
controller.
A common group is managed by mode than two main controllers.
A sub system controller which exceeds the management range of the main system controller of two or more.
