I2
When input I2 is on, data of D10 is divided by data of D20. The
quotient is set to D30, and the remainder is set to D31.
Note: Destination uses two word operands in the division operation of word data type, so do not use data register D7999
as destination operand D1, otherwise a user program syntax error occurs, and the ERROR LED is lit. When using a bit oper-
and such as internal relay for destination, 32 internal relays are required; so do not use internal relay M2521 or a larger
number as destination operand D1.

Note: Destination uses four word operands in the division operation of double-word data type, so do not use data register
D7997 through D7999 as destination operand D1, otherwise a user program syntax error occurs, and the ERROR LED is
lit. When using a bit operand such as internal relay for destination, 64 internal relays are required; so do not use internal
relay M2481 or a larger number as destination operand D1.

Note: Destination uses four word operands in the division operation of long data type, so do not use data register D7997
through D7999 as destination operand D1, otherwise a user program syntax error occurs, and the ERROR LED is lit. When
using a bit operand such as internal relay for destination, 64 internal relays are required; so do not use internal relay
M2481 or a larger number as destination operand D1.
