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...
