cos404co.h File Reference

Detailed Description

This module implements the variables and callback functions for the object dictionary from CiA 404 (controller). The module adds the following objects to the object dictionary:

Index	Description	Function / Variable	Configuration Symbol
6410h	CO effective controller output Y (int16_t)	Cos404_Idx6410()	-
6421h	CO automatic/manual mode switch A/M	Cos404_Idx6421()	-
6422h	CO controller on/off	Cos404_Idx6422()	-
7402h	CO set point W (int16_t)	Cos404_Idx7402()	-
7450h	CO proportional band Xp1 (int16_t)	Cos404_Idx7450()	-
7451h	CO proportional band Xp2 (int16_t)	Cos404_Idx7451()	-
7452h	CO integral action time Tn1 (int16_t)	Cos404_Idx7452()	-

Function Documentation

Cos404_CO_GetConfig()

Cos404_CO_Config_ts * Cos404_CO_GetConfig

(

uint8_t

ubChannelV

)

Parameters

[in]

ubChannelV

Controller channel

Returns

Parameter value for given channel (or 0 if out of range)

Getter helpers for application templates to access controller parameters.

Cos404_CO_Process()

void Cos404_CO_Process

(

uint8_t

ubChannelV

)

Run one controller process step for the given channel.

Parameters

[in]

ubChannelV

Controller channel

Note

This function shall be called after the COS 404 module has been initialized by Cos404_ParmInit().

This function executes one PID step for the controller channel defined by ubChannelV. It reads the set point from object 7402_h, applies the configured proportional band (7450_h, 7451_h) and integral action time (7452_h), and writes the resulting output value to object 6410_h.
