CLR (Clear) Ladder Logic Instruction

The Clear instruction is a ladder logic rung output instruction that clears all the bits (sets them to zero) of the Destination tag. The instruction is enabled when the preceding logic is true and disabled otherwise. The destination must be a value tag. List of possible arguments DESTINATION can be any of the following data types. … Read more

BTD (Bit Field Distribute) Ladder Logic Instruction

The BTD instruction is a ladder logic rung output instruction that copies user determined bits from the Source, shifts the bits to a user defined position and places the result in the Destination. The instruction is enabled when the preceding logic is true and disabled otherwise. The destination must be a value tag. Source Bit is … Read more

BSR (Bit Shift Right) Ladder Logic Instruction

The BSR instruction is a ladder logic rung output instruction that shifts data in an array one bit to the right every execution. The instruction loads the value of the source bit into the bit pointed to by the Length. The instruction is enabled when the preceding logic is true and disabled otherwise. When the … Read more

BSL (Bit Shift Left) Ladder Logic Instruction

The BSL instruction is a ladder logic rung output instruction that shifts data in an array one bit to the left every execution. The instruction loads the value of the source bit into the lowest bit of the array. The length defines the unload bit. The instruction is enabled when the preceding logic is true … Read more

AVE (Average) Ladder Logic Instruction

The Average instruction is a ladder logic rung instruction that calculates the average of values in an array and places the calculated value in the Destination tag. The instruction is enabled when the preceding logic is true and disabled otherwise. The Average ladder instruction uses the Control data type to calculate the average. Insure the … Read more

ATN (Arc Tangent) Ladder Logic Instruction

The Arc Tangent instruction is a ladder logic rung output instruction that takes the arc tangent of the Source value and places the result in the Destination tag. The instruction is enabled when the preceding logic is true and disabled otherwise. The values can be constants, tags or any combination. The result will be between … Read more

ASN (Arc Sine) Ladder Logic Instruction

The Arc Sine instruction is a ladder logic rung output instruction that takes the arc sine of the Source value and places the result in the Destination tag. The instruction is enabled when the preceding logic is true and disabled otherwise. The values can be constants, tags or any combination. The Source must be between -1 and … Read more

ACS (Arc Cosine) Ladder Logic Instruction

The Arc Cosine instruction is a ladder logic rung output instruction that takes the arc cosine of the Source value and places the result in the Destination tag. The instruction is enabled when the preceding logic is true and disabled otherwise. The values can be constants, tags or any combination. The Source must be between -1 and … Read more
