What Do You Want to Configure?
1. Measurement Source
You can assign DC voltages, thermocouples, RTDs, and on/off signals based on contacts
and voltages to channels to take measurements. The measurement section is modular, so it
can be expanded as necessary.
Input signals are sampled at the scan interval and converted to measured values through
A/D conversion.
Setting Measurement Conditions (Setting menu: Measurement settings)
Item Reference
Setting the scan interval →page 1-75
Setting the operation mode of a module (AI module: 2ch mode/10ch mode, DI
module: normal/remote)
→page 1-76
Setting the A/D integration time of an AI module (analog input module) →page 1-77
Setting how to detect over-range values →page 1-75
2. Configuring Measurement Channels
You can set measurement conditions for each channel based on the input. You can calculate
the difference between two input values or convert input values to measurement values with
units that suit your purpose.
Alarms can be generated when measured data exceeds or goes below specified values.
Information that indicates alarm occurrence can be shown on the screen. Digital output
channels (DO channels) can be used to transmit relay contact signals.
You can change channel colors and assign tags to channels.
