In the following cases, 'CH1 Maximum value' (Un\G404) is updated with the current value.
• When 'Operating condition setting request' (Un\G70, b9) is turned offonoff, and the setting is changed
• When 'CH1 Maximum value reset request' (Un\G473) is turned offonoff
■Buffer memory address
The following shows the buffer memory address of this area.
Buffer memory name
CH Maximum value
CH Maximum value (In FX2N allocation mode function)
■Refreshing cycle
The value is updated every conversion cycle.
• For the channel to which the averaging processing is specified, the maximum and minimum values are
stored at every averaging processing time.
• When the scaling function, shift function, and digital clipping function are used, values calculated by each
function are stored in Maximum value and Minimum value.
CH1 Minimum value
The minimum value of the digital operation value is stored in 16-bit signed binary value.
