Operands:
S
1
: Dividend S
2
: Divisor D: Quotient and remainder
Explanations:
1. If S
1
and S
2
are used in device F, only 16-bit instruction is applicable.
2. If D is used in device E, only 16-bit instruction is applicable.
3. In 16-bit instruction, D occupies 2 consecutive devices.
4. In 32-bit instruction, D occupies 4 consecutive devices.
5. See the specifications of each model for their range of use.
6. This instruction divides S
1
and S
2
in BIN format and stores the result in D. Be careful with the positive/negative
signs of S
1
, S
2
and D when doing 16-bit and 32-bit operations.
7. This instruction will not be executed when the divisor is 0. M1067 and M1068 will be On and D1067 records the
error code 0E19 (hex).
8. In 16-bit BIN division,
+1
= /
Quotient Remainder
When D serves as a bit device, it can designate K1 ~ K4 and construct a 16-bit result, occupying consecutive 2
groups of 16-bit data and bringing forth the quotient and remainder. ES/EX/SS is able to bring forth only quotient
without the remainder.
9. In 32-bit BIN division,
+1
/ =
+1 +1 +3 +2
Quotient Remainder
When D serves as a bit device, it can designate K1 ~ K8 and construct a 32-bit result, occupying consecutive 2
groups of 32-bit data and bringing forth the quotient and remainder.
Program Example:
When X0 = On, D0 will be divided by D10 and the quotient will be stored in D20 and remainder in D21. On/Off of the
highest bit indicates the positive/negative status of the result value.
