■Buffer memory address
The following shows the buffer memory address of this area.
Buffer memory name
CH Digital operation value
CH Digital operation value (in FX3 allocation
mode function)
When the scaling function, shift function, digital clipping function, or difference conversion function is not used,
a value which is the same as the one in 'CH1 Digital output value' (Un\G400) is stored.
CH1 Maximum value
The maximum value of the digital operation value is stored in 16-bit signed binary value.
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
