Writing cam data
Writing cam data
Cam data define the type and function principle of the cams and their assignment to the
tracks.
Cam data are stored in the parameter DB, starting at address 108.0. These data are
grouped in packets, each consisting of 16 cams.
Cam data are active immediately after having been written.
To write cam data without using the programming interface:
1. Enter the new values in the parameter DB.
2. Download the parameter DB to the CPU.
3. Set the trigger bits at the channel DB (CAM1WR_EN to CAM8WR_EN)
4. Call FB CAM_CTRL in the cyclic user program.
