DECS-250 CAN Communication
27 • CAN Communication
Introduction
CAN Bus interface 1 facilitates communication between the DECS-250 and optional modules such as the
Contact Expansion Module (CEM-2020) and Analog Expansion Module (AEM-2020). Refer to the
chapters Contact Expansion Module and Analog Expansion Module for more information.
CAN Bus interface 2 enables the DECS-250 to provide generator and system parameters to a generator
controller such as the Basler DGC-2020. CAN 2 also permits DECS-250 setpoint and mode control from
an external device connected to the CAN. The parameters sent over CAN 2 are listed in this chapter.
Both CAN Bus interfaces utilize the SAE J1939 messaging protocol.
Refer to the Communication chapter for CAN port configuration and the Terminals and Connectors
chapter for wiring.
CAN Parameters
Supported CAN parameters are listed in Table 27-1. The first column contains the parameter group
number (PGN), the second column contains the parameter name, the third column contains the unit of
measurement for a parameter, the fourth column contains the suspect parameter number (SPN), and the
fifth column contains the broadcast rate for a parameter.
