The A/D converter module adds the set shifting amount to conversion
value to the scaling value (digital operation value) and stores in the buffer
memory. Fine adjustment can be performed easily when the system
starts.
When the input voltage or current exceeds the input range, the maximum
value of the scaling value (digital operation value) can be set to 20000,
and the minimum value can be set to 0 or -20000.
This function subtracts the difference conversion reference value from the
scaling value (digital operation value) and stores the acquired value in the
buffer memory.
This function logs the digital output value or scaling value (digital
operation value). The data of 10000 points can be logged for each
channel.
This function performs the A/D conversion of analog input value (voltage
or current) from a source such as a flow meter and integrates the digital
output value.
The function stores up to latest 16 recodes of errors and alarms occurred
in the A/D converter module to the buffer memory.
This function collects errors and alarms occurred in the A/D converter
module and stores to the CPU module or the head module.
Clearing the error from the system monitor at error occurrence is
possible.
The offset/gain value of the user range setting can be saved or restored.
