47

* S is less than S,,1,, and S,,2,, - bit device D is ON

The content of the source device (S) is copied to the destination (D) device when the control input is active. If the MOV instruction is not driven, no operation takes place.

89

90

For 32bit instructions (DMOV), two devices will be copied to the destination device, for example DMOV D1 D5, the result is D1→D5, D2→D6.

This instruction copies a specified number of digits from a 4 digit decimal source (S) and places them at a specified location within a destination (D) number (also a 4 digit decimal). The existing data in the destination is overwritten.

115

116

* M,,1,, - The source position of the 1st digit to be moved

117

* M,,2,, - The number of source digits to be moved

118

* n- The destination position for the first digit

119

120

Allows BCD numbers to be manipulated in exactly the same way as the ‘normal’ SMOV manipulates decimal numbers, i.e. This instruction copies a specified number of digits from a 4 digit BCD source (S) and places them at a specified location within a destination (D) number (also a 4 digit BCD number).

121

122

To select the BCD mode the SMOV instruction is coupled with special M coil M8168 which is driven ON. Please remember that this is a ‘mode’ setting operation and will be active, i.e. all SMOV instructions will operate in BCD format until the mode is reset, i.e. M8168 is forced OFF.

A copy of each data bit within the source device (S) is inverted and then moved to a designated destination (D).

157

158

This means each occurrence of a ‘1’ in the source data will become a ‘0’ in the destination data while each source digit which is ‘0’ will become a ‘1’. If the destination area is smaller than the source data then only the directly mapping bit devices will be processed.
