• 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.

„ 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)

4.3.1 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. z 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.

• 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.

NOTES

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 analog input is selected. 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.
