Hello Milosh, You can use the PWM either on the SB output or on the on-board output. But unfortunately not both at a time. So a maximum of 2 PWM outputs can be used in one S7-1200 system. Refer this - Operation of Pulse Outputs If you need more than two PWM output, one of the next choice is to go for additional CPU and make the CPUs to speak with each other. |
