3.2.17 Simplified analog I/O function

3 - 48
This function enables an unused channel of the Q62HLC to be used as a
simplified thermocouple/micro voltage input module, analog-digital converter
module, or digital-analog converter module.
The execution of the simplified analog I/O function is performed in manual
control mode 2. Set 3 in Control mode (buffer memory address: 50, 82).
The following describes how to use the analog input and analog output.
(1) Analog input
Monitors Measured value (PV) (buffer memory address: 9, 10).
(2) Analog output
Set the digital value 0 to 4000 (current value is 4 to 20mA) of the analog output
to MAN output setting (buffer memory address: 51, 83).
When not using the analog output, set a value in the range of -32768 and -1.
*1: Functions equivalent to the analog-digital converter module or digital-analog
converter module are not available.
*2: The output is near 0mA.
REMARKS
The following describes the specifications of conversion speed for the simplified
analog I/O function.
