You specify the number of dispatchable generators, loads, boilers for heat, renewable resources, and so on in
the DMC490 Configuration Tools.
Up to 32 resources can be connected in the microgrid, with maximum per device type as follows.

DMC490 Operation Modes

The MGC optimization function has different modes of operations, which determine whether optimization is on
or off.
Modes of Operation
The modes of operation are:
•
Legacy (Off) — Off — In this mode, no optimization takes place and no communication occurs with the
resources and assets in the microgrid. When a user selects this mode, the microgrid continues to operate
using the last configured values. For example, when a diesel generator is on, and the user activates Legacy
(Off) mode, the diesel generator continues to operate.
The Analog Value code for this mode is 0.
• Auto — On — In this mode, Optimization occurs and the optimal solution is communicated to the resources
and assets.
The analog value code for this mode is 1.
• Advisory — On — In this mode, Optimization occurs, but the optimal solution is not communicated to the
resources and assets. When there is a problem in the microgrid, the unit automatically switches to this
mode to prevent commands from being sent to devices. To fix this issue, inspect the system, including
generation and storage devices, local controllers, and communication links.
The analog value code for this mode is 2.
Note:: Delay is associated in the Process of transitioning between the modes. The mode cannot be abruptly
changed from off to Auto; it first switches to Advisory mode, and if the optimization problem is feasible,
and an optimal solution is found, the operation mode changes from Advisory to Auto at the end of the
problem-solving phase. This transition is indicated by "Running Optimal Dispatch" on the main HMI
pane.
