| PG Label | Request for Repetition Rate |
| PG Acronym | REQRR |
| PG Notes | Message allowing the system to adapt the bus bandwidth to the needs of the user of the message. The user of a message with a particular PGN can request a specific, desired repetition rate. This includes the default rate that can be requested with a value of 0x0000. If it is possible for the source of the message with the requested PGN to deliver the message with the desired repetition rate, it will honour the request. CFs are not required to monitor the bus for this message. If another CF cannot or does not want to use the requested repetition rate, which is necessary for systems with fixed timing control loops, it may ignore this message. The requester of a varied rate shall wait 250 ms after transmission of this request message and, if no response for repetition rate has been received, the requester shall assume that the request was not accepted. Any source of the requested PGN that honours a new rate, shall send the response for repetition rate and wait 250 ms before switching to the new rate. If the source of the requested PGN has also received a request with the repetition rate of 0x0000, within the 250 ms of receiving a request for a different rate, it shall use the default rate. |
