Description

The High Current Power Distribution Module (HCPDM) is a  intelligent I/O expansion module designed for 12Vdc systems, configured and controlled over a J1939 CAN data link. The PDM features eight high current outputs, two low current outputs, and 6 configurable analog inputs. 

An external device such as a Powerview Display, uControl Hydraulic controller, or any customer supplied controller will send configuration messages to the HCPDM over the CAN data link to configure the desired behavior of the analog inputs and high current outputs. Handshaking messages are returned to confirm the configuration status. This configuration data is then retained in non-volatile memory indefinitely until it is overwritten when it receives another configuration command. This means the HCPDM only needs to be configured one time.

During operation, an external device will continually send messages over the CAN data link to control the state of each of the outputs. Fault conditions are monitored by the HCPDM and in the event of a fault, the affected outputs or the entire unit will be shut off and the fault conditions reported.

The HCPDM will continually broadcast analog input status, fault status, output current status, and a host of other information pertaining to the state of the module. 

Communication with the HCPDM is seamlessly integrated into our Powervision displays using a built in app. When developing using a different controller, it is recommended to review the quick reference material in this article and the condensed message list in section 7 of the reference manual. The details for each message can be found throughout the manual. The message list is almost identical to the IX3212 PDM with added messages for new features and current limit values.

CAN Communication Quick Reference

The HCPDM uses one PGN for all communications to and from an external device. Messages are multiplexed using byte one of the data payload as the message ID. Destination and Source Addresses are used in the message ID to further discriminate the messages. The external device will always use address 17 as its source address. The source address of the PDM is configurable through input wiring.

Baud Rate: 250K

Protocol: J1939

PGN: 61184 decimal (0xEF00 hex)

Source Address: Default of 40 (0x28hex), set using SA digital inputs, range 40 - 47

Communicating Device Address: 17 decimal, 0x11hex

Message ID from HCPDM (Tx):0x14EF1128 -  HCPDM SA 0x28 is configuration dependent

Message ID to the HCPDM (Rx):0x14EF2811 - HCPDM SA 0x28 is configuration dependent

Message Identifier - Data is multiplexed using Byte 1 to identify the message (message identifier) and its contents. Data Byte 2 is sometimes used in addition to identify the input/output channel number being configured.

See Section 7 in the Reference Manual for a condensed list of all byte definitions.
