• Changing nine or more bit ON/OFF duty output phases

If multiple P_DUTY_8PT_ function blocks are connected, nine or more bit ON/OFF duty output phases can be changed.

When connecting multiple P_DUTY_8PT_ function blocks, connect LINKOUT of the preceding FB with LINKIN of the

following FB, set PRIMARY of the preceding FB to TRUE, and PRIMARY of the following FB to FALSE. The value of CTDUTY

and DELAY of the first FB is applied to the value of CTDUTY and DELAY of the following FB.

Execution cycle: T: 100ms

Control output cycle: CTDUTY = 2.0s

Input: MV0 = 40%, MV1 = 20%, MV2 = 40%, MV3 = 15%, MV4 = 30%, MV5 = 100%, MV6 = 0%, MV7 = 35%

Output ON delay time: DELAY = 0.1s

Lead FB specified: PRIMARY = TRUE

Control output cycle: CTDUTY = Same as CTDUTY of the preceding FB (2.0s in this example)

Input: MV0 = 25%

Output ON delay time: DELAY = Same as DELAY of the preceding FB (0.1s in this example)

Start FB specification: PRIMARY = FALSE
