(5) Signal timing of the cam switch function
The following figure shows the signal timing of the cam switch function.
• Only Cam switch (Output 1) is used.
• Coincidence output 1 is assigned to CH1.
• "1: Stage 1" is assigned to "Cam switch output unit assignment setting".
• "0: CH1" is assigned to "Cam switch output 1 channel assignment setting".

Cam switch output signal (RWr2) turns on regardless of CH  Count enable command (RY24, RY3C).
No. Description
1)
When CH1 Cam switch execute command (RY26) is turned off then on, the step setting of Cam switch (Output 1) is acquired and
CH1 Cam switch execute (RX26) turns on. (If the value is changed while the cam switch function is in operation, the change is
ignored.)
2) The cam switch function operates when CH1 Cam switch execute (RX26) turns on.
3)
CH1 Present value (RWr10 to RWr11) and the step setting of Cam switch (Output 1) are compared and the result is output from Y0
of the extension output module. The output status can be checked by Cam switch status (Output 1) (RWr2.b0) of Cam switch output
signal (RWr2).
4)
When CH1 Cam switch execute command (RY26) is turned off, the operation is as follows:
• CH1 Cam switch execute (RX26) turns off.
• Cam switch status (Output 1) (RWr2.b0) becomes 0.
• Y0 of the extension output module is turned off.
