■Buffer memory address
The following table shows the buffer memory address of this area.
Buffer memory name
CH Alert definition
CH Alert definition (If using FX3 allocation mode)
*1 For details, refer to Page 134 CH1 Event.
CH1 Temperature process value (PV)
The values that implemented the following processes are stored in the detected temperature values.
*1
• Linearize process
• Sensor process
• Primary Delay Digital Filter
*1 Not implemented when using external (other analog module) inputs.
The value to be stored differs depending on the value stored in 'CH1 Decimal point position' (Un\G400). (Page 128 CH1
Decimal point position)
• If there is nothing after the decimal point (0): Stored as is.
• If there is 1 digit after the decimal point (1): The x10 value is stored.
One of the following values is stored depending on the input type.
• Internal temperature inputs: Input range lower limit-5% of span to input range upper limit+5% of span
• Internal low-voltage inputs: Scaling lower limit-5% of span to scaling upper limit+5% of span
• External inputs: External input range lower limit-5% of span to external input range upper limit+5% of span
