SEQUENCE_64 generates a time sequence of up to 64 states. In the resting state the output STATE is set to -1, thereby demonstrating to that the module is not active. A rising edge at START starts the sequence and the output switches to 0. After the waiting time PROG[0] the module switch next to STATE = 1, waits the time PROG[1], switches to STATE = 2, etc. .. until the output STATE reached the value of SMAX. After the waiting time PROG[SMAX], the device returns to the idle state (STATE = -1). A change to a new state STATE trigger of the output TRIG with a TRUE for one PLC cycle. With TRIG easily downstream modules can be controlled. With the input RST, the device can also be reset in the initial state at any time during the process of a sequence. |
