10 Application Instructions API 202-313 Operands: S 1 : Source device 1 S 2 : Source device 2 S 3 : Source device 3 Explanations: 1. EH3 V1.40 and SV2 V1.20 (and above) are supported. 2. The absolute value of the difference between S 1 and S 2 is compared with the absolute value of S 3 . Take ORZ> for example. If the comparison result is that the absolute value of the difference between S 1 and S 2 is greater than the absolute value of S 3 , the condition of the instruction is met. If the comparison result is that the absolute value of the difference between S 1 and S 2 is less than or equal to the absolute value of S 3 , the condition of the instruction is not met. 3.
The instruction ORZ ※ is connected to a contact in parallel. 4. A 32-bit counter (C200~C255) must be used with the 32-bit instruction DORZ ※ . If it is used with the 16-bit instruction ORZ ※ , a program error will occur, and the ERROR LED indicator on the PLC will blink. Program Example: If M0 is On, or the absolute value of the difference between D10 and D11 is greater than K200, Y0 will be On.
