APPLICATION-SPECIFIC FUNCTION: CAM BLOCK (CAM TIMER)
If the FORWARD input changes from OFF to ON, a group of 8 integral cam wheels will move forward one step. The function presents ON or OFF values (parameter inputs) for the number of the step indicated on the POSITION output (0 to 49) on the 8 outputs (OUTPUT 1 to OUTPUT 8).
If the REVERSE input changes from OFF to ON, the group of 8 cam wheels will move back one step.
The FORWARD input has priority over the REVERSE input.
The cams have the same number of steps.
The Parameters tab in the parameterisation box is used:
An ON value on the RESET TO ZERO input sets the cam wheels to the 0 position and forces POSITION to 0. This input has priority over the FORWARD and REVERSE inputs.
If they are not connected, FORWARD or REVERSE are fixed at OFF.
If it is not connected, RESET TO ZERO is fixed at OFF.
