PLUS+1 CAN I/O Module Communications Protocol Technical Information

Message Timing Information

In the following section on message structures, the repetition time is specified. If the repetition time is set to zero, then the message is disabled and is not sent. If the repetition time is not zero, then the message is active and is transmitted periodically at the interval specified by the repetition time. (The following tables identify the repetition time as the Rate.)

To change the repetition time, use the Configure Timing message (SUBCMD 12.)

Some of the messages are referred to as optimized and others are not. Optimized messages have the designation OPT in the title of the message. Optimized messages have the data for several inputs or outputs of a certain type contained in the message. This minimizes the number of messages needed to be sent on the CAN bus in order to reduce bus traffic.

Non-optimized (regular) messages typically have only the data for a single input or output. In general optimized messages are used as the default so that all data can be communicated between the I/O module and the controller. A system designer has the option of turning off optimized messages and using regular messages instead. Typically, the default set of messages is adequate for most systems.

Messages Based on the Sub-Identifier

This frame is transmitted to the I/O device continuously with a default cycle time. If the message does not arrive in the predefined cycle time, the slave will set the output to a default value. The default value and the timeout time can be defined. For more information see Configure Timing (SUBCMD 12) and Configure Output Default (SUBCMD 13) in the PLUS+1 CAN I/O Module Communications Technical Information document (SauerDanfoss part 520L1029). If no default values have been defined, the shown timeout value will be used. If no default output value is defined, the I/O slaves will use a zero as a default value. This message will be interpreted from the slave in packed and unpacked data transmission mode. Commands for non-existing outputs will be ignored.

Parameters Stored in Non-Volatile Memory

Several parameters of the system have to be stored in the non-volatile memory so that the parameters are available after a power cycle. These parameters can always be accessed and modified with the diagnostic tool. Besides communication parameters some predefined start up values for the outputs and the configuration values for the outputs and the inputs are stored in the non volatile memory.
