(1) A type change represents a major functional feature difference in a peripheral module. Within a peripheral type, there may be minor differences between devices that do not affect the basic functionality of the module. These device-specific differences are listed in the C2000 Real-Time Control Peripherals Reference Guide and in the peripheral reference guides.
(2) TMX samples will come with the ZEP designator. The designator will change to ZFE after TMS.
