5ASIC Interface

The registers that determine both the hardware function of the ASIC as well as telegram processing are described in the following.

5.1 Mode Register

Parameter bits that access the controller directly or which the controller directly sets are combined in two mode registers (0 and 1) in the SPC3.

5.1.1 Mode Register 0

Setting parameters for Mode Register 0 takes place in the offline state only (for example, after switching on). The SPC3 may not exit offline until Mode Register 0, all processor parameters, and organizational parameters are loaded (START_SPC3 = 1, Mode-Register 1).

*) When Spec_Clear_Mode (Fail Safe Mode ) = 1 the SPC3 will accept data telegramm with a data unit=0 in the state Data Exchange. The reaction to the outputs can be parameterized f.e. in the parameterization telegram ( only available from version Step C).

**) When using a big number of parameters to be transmitted from the PROFIBUS-Master to the slave the Auxiliary buffer ½ has to have the same size like t he Parameterization buffer. Sometimes this could reach the limit of the available memory space in the SPC3. When Spec_Prm_Puf_Mode = 1 the parameterization data are processed directly in this special buffer and the Auxiliary buffers can be held compact.
