Step 3 Installing the Hardware

For using an expansion PC card un der Windows, yo u have to let the OS detect the I /O addresses and I RQ to be used by the PC card. The process is referred to as installing the hardware.
When using more than one PC card, install the PC car ds one at a time and do not i nstall the next PC card until setup is complete for the previous PC card.

Turning on the PC

Turn on the power to your PC.
CAUTION
- The PC card cannot be properly installed unless the resources (I/O addre sse s and i nterr upt le vel) for the PC card can be allocated. Before attempting to install the PC card, first determine what PC resources are free to use.
- The resources used by each PC car d do not de pend on the locat ion of the PC cards sl ot or the PC car d itself. If you remove two or more PC cards that have already been insta lled and then remount one of them on the computer, it is unknown that which one of the sets of resources previously assigned to the two PC cards are assigned to the remounted PC card. In this case, you mus t ch eck th e resource settings.

Using the “Diagnosis Report” feature report s the driver settings, the presence or absence of the PC card, I/O status, and interrupt status.

Check Method

Connect the PC card to a remote device to test the input/output and check the execution environment. For this PC card, prepare an external power supply (12 to 24 VDC). The Check Mate (CM-32(PC)E) comes in handy when you check digital I/O PC cards. Check the PC card with the factor defaults untouched.

Setup Troubleshooting

Symptoms and Actions

No output can be obtained. Use API-TOOL Configuration to check whether the PC card name setting is wrong.
The PC card works with the Diagnosis Program but not with an application. The Diagnosis Progra m is co ded with A PI-TO O L fu ncti o ns. As lo ng as the PC c ar d ope ra tes w ith th e
Diagnosis Program, it is to operate with other applications as well. In such cases, review your program while paying attention to the following points:
- Check the arguments to functions and their return values.
- When the PC card is an isolated type, it has a time lag for its response between the output by a function and the actual output. Consider the execution intervals between functions.
The OS won’t normally get started or detect the PC card. [Windows XP Turn off the power to your PC, then unplug the PC card. Restart the OS and delete the PC card settings
of API-TOOL Configuration. Turn off the PC again, plug the PC card, and restart the OS. Let the OS detect the PC card and use API-TOOL Configuration to register PC card settings.

Connecting Input Signals

Connect the input signals to a device which can be current-driven, such as a switch or transistor output device. The connection requires an external power supply to feed currents. The PC card inputs the ON/OFF state of the current-driven device as a digital value.

The input circuits of interface blocks of the PIO-16/16L(CB)H is illustrated in Figure 3.3. The signal inputs are isolated by opto-couplers (ready to accept current sinking outp ut signal s). The PC card therefore requires an external power supply to drive the inputs. The power requirement for each input pin is about 5.1 mA at 24 VDC (about 2.6 mA at 12 VDC).

Figure 3.5. Output Circuit
The output circuits of interface blocks of the PIO-16/16L(CB)H is illustrated in Figure 3.5. The signal output section is an opto-coupler isolated, open-collector output (current sink type). Driving the output section requires an ex te rn al po we r supp l y.
The rated output current per channel is 100 mA at maximum. The output section can also be connected to a TTL level input as it uses a low-saturated transistor for
output. The residual voltage (low-level voltage) between the collector and emitter with the output on is
0.5V or less at an output current within 50 mA or at most 1.0V at an output current within 100 mA. A zener diode is connected to the output transistor for protection from surge voltages. A PolySwitch-
based overcurrent protector is provided for every eight output transistors. When the overcurrent protector works, the output section of the PC card is temporarily disabled. If this is the case, turn of the power to the PC and the external power supply and wait for a few minutes, then turn them on back .

4. Function

4. Function
This section describes the features of the PC card. Each function described here can be easily set and exec uted by using the bundle d API driver library. For
details, refer to API-DIO HELP available after installation.

Data I/O Function

Data Input

When the input data is “ON”, “1” is input to the relevant bit. When the input data is “OFF”, in contrast, “0” is input to the relevant bit.

Data Output

When “1” is output to the relevant bit, the corresponding transistor is set to “ON”. When “0” is output to the relevant bit, in contrast, the corresponding transistor is set to “OFF”.
CAUTION
When the PC is turned on, all output ar e reset to 0 (OFF).

Monitoring Output Data

The PIO-16/16L(CB)H can read the state of the data currently being output without affecting the output data.
35
Page 43
4. Function

Digital Filter

Using this feature, the PIO-16/16L(CB)H can apply a digital filter to every input pin, thereby preventing the input signal from being affected by noise or chattering.

Digital Filter Function Principle

The digital filter checks the input signal level during the sampling time of the clock signal. When the signal level remains the same for the digital filter set time , the digital filter recognizes that signal as the input signal and changes the signal level of the PC
If the signal level changes at a frequency shorter than the set tim e, therefore, the level c hange i s ignored.

Set Digital Filter Time

Set the digital filter time to 0 to 20 (14h). Setting the digital filter time to 0 disables digital filtering. It is set to 0 when the power is turned on . Figure 4.2 shows the relationships between digital filter time settings and the actual digital filter times.

4. Function

Interrupt Control Function

The PIO-16/16L(CB)H can use all of the input signals as interrupt request signals. The PC card can generate an interrupt request signal to the PC when the i nput si gnal c hange s from High
to Low or from Low to High. When the digital filter (described above) is used, interrupt requests are generated by input signals that
have passed through the filter.

Disabling/Enabling Interrupts

Interrupt mask bits can be used to disable or enable the individual bits for interruptions. Once a certain bit has been interrupt-disabled, no interrupt occurs even when the corresponding input signal changes its level. To let interrupts occur, enable the corresponding interrupt mask bit for interruptions.
CAUTION
All of the interrupt mask bits are interrupt-disabled wh en the power is turned on.

Selecting the Interrupt Edge

Interrupt edge select bits can be used to set the input logic for interruption bit by bit. If you set an interrupt edge select bit to 0, an interrupt occurs when the input value to the corresponding bit changes from 0 to 1 (at the fall of the input signal from High to Low). If you set an interrupt edge select bit to 1, an interrupt occurs when the input value to the corresponding bit changes from 1 to 0 (at the rise of the input signal from Low to High).
CAUTION
When the power is turned on, a ll of th e inte rrup t edge select bits are set to 0 so that an interrupt occurs when the input valu e cha ng es fr o m 0 to 1 (at the f al l of th e inpu t signa l from High to Low).

Clearing the Interrupt Status and Interrupt Signal

Interrupt status bits are used to identify the input signal bit being used for requesting an interrupt. When an interrupt status is input, the interrupt request signal and the interrupt status are cleared automatically.
CAUTION
- All of the interrupt status bits are set to 0 wh en the power is turned on.
- If an interrupt mask bit has been set to disable interrupts, the interrupt status bit is not set even whe n the input signal changes its level.
