Are interrupt inputs and fast counter inputs available?

FAQ #100063

 

Yes. The PCD1.M137 has 1 interrupt input, the PCD2.M1x7 has 2 interrupt inputs (or 1 fast counter) and the PCD2.M487 has 4 interrupt inputs (or 2 fast counters) already built into the base unit. When a signal changes at the inputs (or when a count value is reached) an interrupt OB will be called in the application program. Further information may be obtained from Technical Information TI 26/353 (Operating system xx7) Detailed information on the programming of these functions may be consulted in Manual 26/797.
