Step 4: Left-click OK.

Step 5: In the Project Window, expand Parameter and double left click PLC Parameter.

Step 6: In the PLC Parameter window, left click Analog I/O.

• Channel 1 and channel 2 can be configured here.
• The Device Setting option will be the starting data register type and number for all analog operations.

Device Setting

• The device setting designated the starting data register address where the analog value is updated.
• 20 WORDs are occupied from the starting data register address.
  • Each WORD can read or write data.
  • The remaining offsets not mentioned in the table below are not used.

Enable/Disable

• To enable the channel for analog input/output, set the value to enabled.
• To disable the channel for analog input/output, set the value to disabled.

Input

• The input signal range sets the range for voltage or current input.
• The ranges are as follows:
  • Voltage:
    • 0V ~ +5V
    • 0V ~ +10V
    • +1V ~ +5V
    • +1V ~ +10V
  • Current:
    • 0mA ~ 20mA
    • 4mA ~ 20mA

Average Count

• If the analog input value can be filtered by the moving window filtering feature, it is possible to set the number of sampling data in the average count field
• The number of samples can range from 1 ~ 255.
  • If the averaging count is set to 0, the moving window filtering feature is disabled.

AD Filter Coefficient (%)

• This is used to set the AD filter coefficient percentage.

AD Max Digit

• This is the maximum digital value for the analog input.

Stop Mode

• If the value of the stop value mode is set to hold, the value will be retained when the PLC is switched to STOP mode.
• If the value of the stop mode is set to clear, the value will NOT be retained when the PLC is switched to STOP mode.

Output

• The output signal range sets the range for voltage or current output.
• The ranges are as follows:
  • Voltage: 0V ~ +10V
  • Current: 4mA ~ 20mA

DA Max Digit

• This is the maximum digital value from the output.

Analog Data Register Offset

• After selecting the starting data register, the following offsets are used to read/write values:

Offset	Description	Range	Read	Write
0	Channel 1 AD Input Value	0 ~ 4,000 (16,000 SW)	✓	–
1	Channel 2 AD Input Value	0 ~ 4,000 (16,000 SW)	✓	–
2	Channel 1 DA Output Value	0 ~ 4,000 (16,000 SW)	✓	✓
3	Channel 2 DA Output Value	0 ~ 4,000 (16,000 SW)	✓	✓

Error

Error Code	Description
1	Input Type Error
2	Output Type Error
3	AD Disconnection Error +1V ~ +5V/+10V: Less than 0.2V 4mA ~ 20mA: Less than 0.8mA

AD Measured Value

• This displays the measured analog value according to the range configuration.

Input Range	Minimum Value	Maximum Value
0V ~ +5V	0	500
0V ~ +10V	0	1,000
+1V ~ +5V	100	500
+1V ~ +10V	100	1,000
0mA ~ 20mA	0	2,000
4mA ~ 20mA	400	2,000

DA Signal Value

• This displays the DA output value according to the range and the voltage/current configuration.

Output Range	Minimum Value	Maximum Value
0V ~ +10V	0	1,000
4mA ~ 20mA	400	2,000

Switch Configuration

The PLC-FB1616 series has two sets of switches on either side of the serial communication port.

• The switch on the right is the important switch.
  • To measure current for either channel 1 or 2, flip respective the switch up (I)
  • To measure voltage for either channel 1 or 2, flip respective the switch down (V).
