Any suggestions how to program a sine wave using a math function? I have a H2-DM1E CPU and a F2-02DA-2 output module (0-5 Vdc) ? This is to use at a customers site for demo , not to control a nactual process. Thanks, Art

    So you want 0 VDC to map to -1 on the SIN and 5V DC (12 bit 4095) to map to +1 on the SIN?

    See the attached project screen shot. The MATH expression is

    MATH WY0 "(0.5 + (SIN(RAD(CT0.Acc)) / 2)) * 4095 "
