RPDO and TPDO Byte Map Menus
The parameters on the RPDO 1–4 Byte Map and TPDO 1–4 Byte Map menus are used to configure
PDOs. RPDO 1–3 and TPDO 1–2 are preconfigured to transmit and receive messages; see
. Modify a preconfigured PDO only if the application does not require the
PDO’s preconfigured functions.
Note: RPDO4 and TPDO 3–4 are reserved for future use.
The menus contain parameters with the same names, allowed values, and data sizes. The only
differences between parameters of the same name are their CAN indexes and default values. For
simplicity’s sake, the following table describes the PDO Byte Map menus’ parameters and
lists the parameters’ CAN indexes and default values.
