This structure contains the configuration informations for a signal. A signal represents a piece of information within the application (a single bit, a bitfield, a integer value, etc...).

Member | Meaning |
|---|---|
Status | This member holds the initial status of the signal. This status will be copied to the signal status during initialization phase by calling |
Width | This member holds the width of the signal in bit in range 1..32 or in byte (1,2, or 4). Note: Interpreting the width of the signal in bit or byte depends on the configuration setting |
Value | This member holds the initial value of the signal. This value will be copied to the signal value during initialization phase by calling |
CallbackFct | This member holds the function pointer to the callback function, which is called during a signal write or a read event. The function must have the following Prototype: void Func (void *, The first parameter is used as a pointer to the actual signal. The second parameter is a pointer to the actual write-value. In case of a read-event it is set to 0. The third parameter is used to identify the event type (see below). |

Event type Id | Meaning |
|---|---|
| The callback-function is called from the signal read function. |
| The callback-function is called from the signal write function. |
