2.6.2 Modbus® Communications
The controller communicates using Modbus
®
as a slave connection with the Modbus
®
master initiating the communication. The
controller seeks the system and alternator parameters and diagnostic information then responds back to the Modbus
®
master.
In addition, the controller accepts information to alter controller parameters including generator set starting and stopping. See
Figure 25. Refer to the List of Related Materials for available Modbus
®
literature.
Note:
Only one Modbus
®
master can be connected to the controller. Examples include the remote serial annunciator and switchgear
applications
