#4/24/2006The timer_sec Linked user block is made up of the following Function Blocks Calc_1, Move_1 ,Calc_2 ,Move_2 ,Bfilt_1
The MOVE block transfers the value of the input signal, SRC, into the output signal, DEST. The data transfer occurs each time the block runs and the ENABLE pin is TRUE. The analog Basic Function Blocks –Rung Block
The Relay Ladder Logic block solves a Boolean equation of Boolean inputs, placing the result in the output variable. This block is a rubber block that accepts maximum of 16 inputs. The equation is a Boolean equation and can be specified using the ladder logic.
Basic Function Blocks –Calc Block
The CALC block performs mathematical operations, defined by EQUAT, on the inputs, A-H, and places the result in the output signal, OUT. The data type of the inputs, A-H, and output, OUT, is implied by the block data type selected in toolbox. The block accepts signals of any analog data type for the inputs and the data type for all inputs and the output must match. This block is a rubber block that accepts a maximum of 8 inputs, A-H. A modification to the equation, EQUAT, requires a download before the change takes effect. The following operators are supported within EQUAT.
(subtract), * (multiply), / (divide), ^ (power),
% (modulus), ABS() (absolute value), NEG() (negate),
RND() (round to nearest integer), SQR() (square root),
COS() (cosine), SIN() (sine), TAN() (tangent), ACS() (arccosine),
Basic Function Blocks –Bfilt Boolean Filter The Boolean Filter block passes a rising TRUE value on the IN pin to the OUT pin if IN remains TRUE for PU_DEL(in milli seconds) time. The block passes a falling FALSE value on the IN pin to the OUT pin if IN remains FALSE for DO_DEL(in milliseconds). Negative
Basic Function Blocks –Compare Block
The compare blocks compares two values and sets an output boolean reflecting the result. The input signal data type is implied by the block data type. Basic Function Blocks –
The Select block moves one of the eight inputs, or the cascade pin into the output, based on the prioritized evaluation of the eight selection pins. Working in ascending order from SEL1 the first TRUE value encountered causes the corresponding input to be moved to the output. If none of the selection pins are TRUE then the cascade pin is moved to the output. Multiple Select blocks may be chained together to create large selection groups. This is a rubber block and accepts a maximum of eight sets of inputs. ELC Salem, VA
Basic Function Blocks –Timer Block
The TIMER block accumulates incremental time into CURTIME while RUN is TRUE. When CURTIME is equal to MAXTIME, AT_TIME transitions to TRUE. If RUN is FALSE then timing is suspended but the value in CURTIME remains. If RESET is TRUE then CURTIME is set to zero and counting is suspended. The AUTO_RS flag can reset the timer after it reaches MAXTIME. In this mode, AT_TIME will be true for one Basic Function Blocks –Pulse Block
The Pulse block generates a boolean one-shot of the specified width (WIDTH in milli seconds) at the output pin on the rising edge of the trigger. Once the pulse is initiated it persists until it times out
