MOD_PARAM: Adjustment of axis parameters

Function description

The MOD_PARAM function is used to adjust a track dynamically. Transferring new data does not require the cam processor to switch to STOP mode.

If the transfer:

is correctly carried out, the new parameters are taken into consideration,
is not successfully carried out, then the cam processor remains in RUN mode with the old values.

The MOD_PARAM function assigns the following parameters to each exchange:

For a more detailed description of how this function operates, refer to the application specific electronic cam manual.

The additional parameters and can be configured.

Description of the parameters

The following table describes the input parameters:

Parameter	Type	Comment
IODDT_Var	IODDT*	IODDT variable corresponding to the channel on which the function is to be carried out. Example: IODDT_Var of type T_CCY_GROUP0
Action	INT	Type of action to be carried out: Action = 0: pre-loading of the exchange zone with the initial adjustment values. Action = 1: pre-loading of the exchange zone with the current adjustment values. Action = 2: sends new values to the module and updates the current parameter zone.
Param1	INT	Param1 must be equal to 0.
Param2	INT	Param2 must be equal to 0.
Param3	INT	Param3 must be equal to 0.
* IODDT represents the set of types associated with a module or a channel on which the function is to be carried out.
