3.26 Basic Instructions

The basic instructions can handle numerical data represented in 16 bits.

3.26.1 Comparison Operation Instructions

(1)The comparison operation instruction is handled as a contact, compares the magnitudes of two pieces of data (e.g. =, >, <), and turns on when the condition holds.

(2)Use the comparison operation instructions in the same manner as the contact instructions of the PLC instructions as indicated below.

•LD, LDI ......... LD=

•AND, ANI ..... AND=

•OR, ORI ....... OR=

(3)There are the following 18 different comparison operation instructions.

Refer to page 142 for details.

(4) The conditions that the comparison operation instructions turn on are as follows.

	98			99	100	101	102

Dn = K100				OFF	ON		OFF

Dn	K100			ON	OFF		ON

Dn	K100			OFF			ON
							OFF
Dn	K100			ON			OFF

Dn	K100			ON		OFF
