1.5.4 Analog Input Port
There is an analog input port in CIE-M10A. This port is connected to 10 bits ADC (Analog
to Digital Converter). User should input 2.6V~3.3V to the ADVREF for reference voltage of
the ADC. ADC_IN0 port is for user
’
s analog sensors, its input voltage should be between 0V
~ ADVREF. The ADC converts the input voltage of the ADC_IN0 (0V~ADVREF) to 0~1023
digital value.
User can read this value through Modbus/TCP and HTTP. User can read the ADC value
from the address of (Digital Input Port A 4) via Modbus/TCP. When user read the
ADC value via a web browser, user can read this value with $a0 variable.
All the input ports are only for the monitoring devices.
1.5.5 Digital Output Ports
The digital output ports can be interfaced with relays or SSR(Solid-State Relay). The
following is an example to interface to relays.
