MoTeC PDM30 - Manual (Page 23)

20 Configuration
The PDM CAN bitrate is user configurable. All devices on the CAN bus must
be set to the same speed. Refer to the Operation section for details about
CAN bitrate configuration.
Standard Messages
The sets of fixed messages to be sent from the PDM are configured in
Standard Messages. Messages sets can be individually enabled and a base
CAN address is configurable.
Most MoTeC logging devices have CAN communications templates available
to receive these messages.
The transmitted CAN messages include Output Voltage, Output Current,
Output Load, Output Status, Input State, Internal Temperature, Battery
Voltage, Global Error, and Total Current. See CAN Output Messages in the
Appendices for details on the CAN messages.
Standard messages are transmitted at 20Hz.
User Defined Messages
Up to four user defined CAN messages to be sent from the PDM can be
configured in Message 0 to Message 3.
Up to 8 channels can be included in each CAN message, with one channel
per message byte.
The CAN address is user configurable in the standard or extended address
ranges.
User defined messages are transmitted at 50Hz.
Functions
Conditions
A condition is a complex logic function that combines a number of channels to
create a new channel. The logic operations include AND, OR, flash and many
more.
The new channel, with a value of either TRUE (1) or FALSE (0), can be used
to directly control an output or it can be used in another condition.
Counters
A counter generates an integer channel value that can be incremented or
decremented on transitions of other logic channels.
Number of Operations
There are a total of 200 logic operations available in the PDM. The number of
operations used is shown in the status line.
