Function blocks24Operation The output is true if any of the inputs is true. Truth table:Connections Input I1, I2 and I3: Boolean valuesOutput (O): 24 bit integer value (packed boolean)PI Type PI controllerIllustrationOperation The output is input I1 multiplied by I2/100 plus integrated I1 multiplied by I3/100.O = I1∑ I2/100+(I3/100) ∑ I1Note: The internal calculation uses 48 bits accuracy to avoid offset errors.Connections Inputs I1: 24 bit integer value (23 bit + sign)Input I2:- 24 bit integer value (23 bit + sign)- Gain factor. 100 corresponds to 1. 10 000 corresponds to 100.Input I3:- Integrator coefficient. 100 corresponds to 1. 10 000 corresponds to 100.Output (O): 24 bit integer (23 bits + sign). The range is limited to 0Ö10000.PI-BAL Type Initialisation block for the PI controllerIllustrationOperation The block initialises the PI block first. When input I1 becomes true, the block writesthe value of I2 to the output of the PI block. When I1 becomes false, the blockreleases the output of the PI controller block which continues normal operation fromthe set output.Note: The block may be used only with the PI block. The block must follow thePI block.Connections Input I1: Boolean valueInput I2: 24 bit integer value (23 bits + sign)I1 I2 I3 O (binary) O (value on display)0 0 0 False (All bits 0) 00 0 1 True (All bits 1) -10 1 0 True (All bits 1) -10 1 1 True (All bits 1) -11 0 0 True (All bits 1) -11 1 0 True (All bits 1) -11 1 1 True (All bits 1) -1I1I2I3PIOI1I2PI-BAL
