Ny-Series Instructions Reference Manual (W560 - Omron NY532-5400 Reference Manual

• You can set H and L so that H + L = 0. If you do so, either QH or QL will always be TRUE. For exam-
ple, the following figure shows the operation when the value of L is −60 and the value of H is 30.
Reference value X
Upper deviation alarm QH
Lower deviation alarm QL
Precautions for Correct Use
• An error occurs if the value of EPS is outside of the valid range. Error changes to TRUE, and Q, QH,
and QL change to FALSE.
• You can use this instruction for safety measures, for example, to turn OFF a temperature control out-
put when a deviation alarm is output. If you do so, design the safety measures so that safety is main-
tained even when an error causes Q, QH, and HL to change to FALSE. For an application example,
refer to the sample programming that is provided for the TimeProportionalOut instruction (page 2-
727).
Version Information
A CPU Unit with unit version 1.02 or later and Sysmac Studio version 1.03 or higher are required
to use this instruction.
Sample Programming
Refer to the sample programming that is provided for the TimeProportionalOut instruction (page 2-727).
