Action instructions
= NGS
Register sign change.
Example: I16 = NGS R89
If input "I16 = 1", the PLC changes the sign of the contents of register R89.
= ADS, = SBS, = MLS, = DVS, = MDS
They may be used to carry out arithmetic operations such as addition (ADS), subtraction (SBS),
multiplication (MLS), division (DVS) and module or remainder of a division (MDS).
Their programming formats are:
The operands may be: Registers, CNC-PLC communication registers and numbers (#) within
±2147483647 or between 0 and $FFFFFFFF.
The result of the operation may be stored in a register or in CNC-PLC communication register
Examples with R100=1234 and R101=100
R89 before 0001 0001 0001 0001 0001 0001 0001 0001
R89 after 1110 1110 1110 1110 1110 1110 1110 1111

() = ADS R100 R101 R102 R102 = 1234 + 100 = 1334
() = SBS R100 R101 R103 R103 = 1234 - 100 = 1134
() = MLS R100 R101 R104 R104 = 1234 x 100 = 123400
() = DVS R100 R101 R105 R105 = 1234 : 100 = 12
() = MDS R100 R101 R106 R106 = 1234 MOD 100 = 34
() = ADS 1563 R101 R112 R112 = 1563 + 100 = 1663
() = SBS R100 1010 R113 R113 = 1234 - 1010 = 224
() = MLS 1563 100 R114 R114 = 1563 x 100 = 156300
() = DVS R100 1000 R115 R115 = 1234 : 1000 = 1
() = MDS 8765 1000 R116 R116 = 8765 MOD 1000= 765
If a division by "0" is performed in the DVS operation, the CNC stops the execution of the PLC program
and it displays the corresponding error message.
