Shift Function - Mitsubishi Electric MELSEC iQ-F FX5 User Manual

Shift function

Adds (shifts) a set conversion value shift amount to a digital output value, and stores the result in the buffer memory area. A
change in conversion value shift amount is reflected to the digital operation value in real time, which facilitates fine adjustment
at system start-up.
Operation
A set conversion value shift amount is added to the digital operation value. The digital operation value with shift addition is
stored in 'CH1 Digital operation value' (Un\G402). The conversion value shift amount is added in every sampling cycle for
sampling processing and is added in every averaging process cycle for averaging processing. After that, the added values are
stored in 'CH1 Digital operation value' (Un\G402). If a value is set to the conversion value shift amount, the conversion value
shift amount is added regardless of turning offonoff 'Operating condition setting request' (Un\G70, b9).
Setting procedure
Set a value for "Conversion value shift amount".
