The range of devices, including those specified as the two destinations are reset, D,,1,, and D,,2,, could be word or bit(Y, M or S). D,,1,, and D,,2,, must be the same kind device.

The number of D,,1,, should be smaller than D,,2,,. If D,,1,, is 32bit counter, then D,,2,, must be 32bit counter too.

The lower n bits (n ≤ 4) of the source address are decoded to the destination address. When n ≤ 3, the high bit of the destination address will be 0.

40

41

* If n=0, the instruction is not executed, if n is not equal to 0~~8, then an error will occur.

42

* When n=8 and the D1, D2 are bit devices, means the points are 256.

43

* When the drive input is OFF, the instruction is not executed and the decoded output of the action is not changed.

44

* When the D parameter is a word device, the range of n is 1 ~~ 4

45

46

Generally, DECOP is used in the real application.

**Points to note**

* The readable range is defined by the largest number storable in a binary format within the number of destination storage bits specified by n, i.e. if n was equal to 4 bits a maximum number within the range 0 to 15 could be written to the destination device. Hence, if bit devices were being used as the source data, 16-bit devices would be used, i.e. the head bit device and 15 further, consecutive devices.

81

* If the stored destination number is 0 (zero) then the source head address bit is ON, i.e. The active bit has a 0 (zero) offset from the head address. However, if NO bits are ON within the source area, 0 (zero) is written to the destination device and an error is generated.

82

* When the source device is a data or word device n must be taken from the range 1 to 4 as there are only 16 source bits available within a single data word.

83

* When the D parameter is a word device, the range of n is 1 ~~ 4

|DSUMP|32|Yes|9

The numbers of active (ON) bits within the source device (S), i.e. bits which have a value of “1" are counted. The count is stored in the destination register (D). If a double word format is used, both the source and destination devices use 32-bit, double registers. The destination device will always have its upper 16-bit set to 0 (zero) as the counted value could never be more than 32.

The range of source data is defined by operands S and n. S is the head address of the source data and n specifies the number of consecutive source devices used.

157

158

The value of all the devices within the source range is summed and then divided by the number of devices summed, i.e. n. This generates an integer mean value which is stored in the destination device (D). The remainder of the calculated mean is ignored.

If X1 and X2 are set for more than 1 second, S900 is set ON. After that, S900 will keep ON, even if X1 or X2 is reset (but T10 will be reset). If X1 and X2 are connected for less than 1 second, X1 or X2 becomes OFF. Then the timer will reset.

201

202

If M8049 (signal alarm is available) is set, the lowest number of S900~~S999 that is set ON will be saved at D8049 (The lowest S number with the ON state). when any signal in S900~~S999 is ON then M8048 is ON.

If X3 is ON, then the alarm signal from S900 to S999 will be reset. If there are more than one alarm signal, then the alarm signal with the smallest number will be reset.

If X3 is ON again, then the next alarm signal from S900 to S999 will be reset. Generally, we will use ANRP instruction.

This instruction performs a square root operation on source data (S) and stores the result at destination device (D). The operation is conducted entirely in whole integers rendering the square root answer rounded to the lowest whole number. For example, if (S) = 154, then (D) is calculated as being 12. M8020 is set ON when the square root operation result is equal to zero. Answers with rounded values will activate M8021.

The instruction coverts the decimal data S to floating digits, and saves the result in D and D+1. Please note that two consecutive devices (D and D+1) will be used to store the converted float number. This is true regardless of the size of the source data (S), i.e. whether (S) is a single device (16-bit) or a double device (32-bit) has no effect on the number of destination devices (D) used to store the floating point number.
