1.1 Unit Functions and Operation
1.1.1 Unit Type
Features of analog input unit
The analog input unit receives various analog values (i.e., voltage, current, and temperature values) from laser analog sensors and pressure sensors and converts them internally into digital values.
• The analog input unit can receive input through a number of channels.
Analog input units: 4 channels (AD4H) / 8 channels (AD8)
Six types of input ranges can be selected to support a variety of connecting equipment.
• The speed of conversion, such as voltage/current range conversion, is as high as 25
μs/channel (non-isolated).
• Converts input analog values into digital data with up to 16 bits in a resolution range of
1/25,000 to 1/62,500.

Buffer function
Description
Averages analog values obtained by sampling and stores them in the I/O area as digital values. It can be selected from No. of averaging times, time average and moving average.
Performs the correction of offset values (addition correct) or gain values
(magnification correction), and stores the data after processing in the I/O area.
This function is to scale-convert values to an easy-to-use data range. Converts values to digital values in the specified range (min. value and max. value), and stores the processed data in the I/O area. This function is convenient if used for unit conversion.
This function compares acquired data with the upper limit and lower limit and turns ON the upper limit relay or lower limit relay if the acquired data exceeds the upper limit value or lower limit value.
This function maintains the maximum and minimum values of acquired data.
Holds the maximum and minimum digital conversion values when the maximum/minimum value hold setting is enabled, and stores the values in provided unit memories for each channel.
Turns ON the disconnection detection flag when input is disconnected or unconnected when selecting the range of 1-5 V 4-20 mA, and warns of the error state.
This function is to store digital conversion values loaded with a desired period.
Any of the changes in user program, external digital input or analog input value can be selected as a trigger.

4.2.2 Unit Setting and Conversion Processing Time
Conversion time varies with the configuration setting conditions.
Isolation setting and conversion processing time
• Isolated: 5 ms/ch • Non-isolated: 25 μs/ch
• The speed of A/D conversion processing will become faster if non-isolation is set. Each channel is isolated by switching the respective photo-MOS relays of the channels at the time of conversion. The photo-MOS relays are always turned ON at the time of non-isolation and the commons will be shared.
• For AFP7AD8, only the non-isolated setting is available.
Conversion processing execution/non-execution setting and conversion processing time
Select the execution or non-execution of the conversion processing of analog input on a channel-by-channel basis. This can save the conversion time for channels that do not execute conversion processing.
Example) Conversion time for four channels
Converted in the order of ch0→ch1→ch2→ch3→ch0→ch1→ch2→ch3→.... (1 cycle = 100 μs at the time of non-isolation)
Example) Conversion time for two channels (with CH2 and CH3 excluded).
Conversion is executed in the order of ch0→ch1→ch0→ch1→ch0→ch1→ch0→ch1→... and the conversion time for CH2 and CH3, which are excluded, is saved. (1 cycle = 50 μs at the time of non-isolation)

4.3 Reading Analog Input Data
4.3.1 Reading Analog Input Data
Basic Operation of Analog Input Processing
(1) Receiving analog input
The analog input unit receives analog input data from devices, such as laser analog sensors and pressure sensors.
(2) Digital conversion processing
Analog input data received by the unit is converted into digital values in sequence automatically in the unit. The converted digital value varies with the setting of the range.
(3) Storage of digital values
A user program is used to read converted digital values as data in the input relay area (WX).
The specified area number varies depending on the installation position of the unit.

4.4 Data Acquisition Timing
Input conversion processing time of analog input unit
Conversion processing time varies with the range and the number of channels in use. The conversion execution/non-execution channel function can save the conversion time for channels that do not execute conversion processing.
Example of 2-channel conversion
Converted in the order of ch0→ch1→ch0→ch1→....
Data acquisition timing of CPU unit
• Digital values converted by the analog input unit are input into the CPU unit at the I/O refreshing timing of the CPU unit.
• The conversion processing of the analog input unit is not synchronized with the I/O refreshing timing of the CPU unit. Therefore, the latest data is input into the operation memory of the CPU unit when the CPU unit implements I/O refreshing.

Overview of Functions
This function is to announce an error with the disconnection detection flag if the input is below a certain value in either range, +1 to +5V of voltage input or +4 to +20 mA of current input.
Voltage input range of +1 to +5 V set: 0.7 V or less; Current input range of +4 to +20 mA set:
2.8 mA max.
• If the input exceeds the above value while the disconnection detection execution relay is turned ON, the disconnection detection flag will be turned OFF automatically, provided that the auto setting has been made.
• If the manual reset setting is made, the disconnection detection flag will be turned OFF by using a user program and turning OFF the disconnection detection execution relay.
• If the configuration-disconnection detection setting has not been made, the function will be disabled with the disconnection detection execution relay turned ON.

ON), digital conversion values for a specified number of data items will be stored in the buffer memory (unit memory) at a specified cycle.

•
Trigger input will be prohibited with the buffer execution relay turned ON after trigger input. Input, if any, will be ignored.
•
If analog input is selected, buffering will start at the rise (or fall) timing of the digital conversion value on the corresponding channel from a specified value. If the value exceeds a threshold value from the beginning, buffering will start at the moment the value exceeds the threshold value again after the value once falls below (or rises above) the set value.
•
Keep in mind that the analog input trigger will generate timing that disables trigger detection depending on the buffer cycle setting.
•
It is possible to start buffering with the trigger input even if the number of pre-trigger data items has not reached a specified number. (The area where pre-trigger data is not acquired is 0).
•
The buffer function will not be executed if “Not use” is selected for the selection of an external input trigger or the selection of input level trigger channel.
•
The buffer function will not be executed if “Not use” is selected for the input trigger channel even if “Analog input level” is selected as “Trigger type” in the configuration menu of the FPWIN GR7.

OFF when the number of buffer data items is reached.
ON when the shared memory has become accessible after completion of buffering.
OFF on completion of buffer data reading.
ON when the number of buffer data items before triggering has reached the set value.

Buffer execution relay
Buffer trigger relay
Buffer data read completion relay
Description
ON to execute the disconnection detection function.
OFF to turn OFF the disconnection detection flag (Xn0).
(Valid for 1 to 5 V and 4 to 20 mA ranges only)
Do not use.
ON to execute the function to compare the upper and lower limits.
OFF to turn OFF the upper limit comparison relay (Xn1) and lower limit comparison relay (Xn2).
Do not use.
ON to execute the max./min. hold function.
Do not use.
Do not use.
When the buffer function is enabled, trigger acceptance will be permitted with the buffer execution relay turned ON.The internal state transition will be initialized with the buffer execution relay turned
OFF.
If "Trigger relay" is set in trigger setting, triggering will start with the trigger relay turned ON.
ON for one scan upon completion of readign buffer data from the shared memory with a user program. Goes to the state of trigger acceptance permitted after clearing the buffer memory.

Resets an error flag.
(Note 1): The I/O numbers in the table indicates offset addresses. The I/O numbers actually allocated are the numbers based on the starting word number allocated to the unit. Example) When the starting word number for the unit is "10", the disconnection detection execution relay of CH0 is Y100, and the error flag reset relay is
Y10F.
(Note 2) The operation of the buvver function (consisting of the buffer execution relay, buffer trigger relay, and buffer data read completion relay) is specified by the output contacts for CH0.
