What is an IO card and how to choose an IO card

The IO card is an industrial-grade remote acquisition and control module, which provides the functions of switching input acquisition, relay output, high-frequency counter and other functions of passive nodes. Multiple modules in the series can be networked on the bus, so that the number of IO points can be flexibly expanded. Modules can be controlled by remote commands.

The module adopts industrial-grade components, 10 30VDC wide voltage input, can work normally in the range of 30 60, and adopts RS232 and RS485 communication modes to interact with the upper bit.

The IO card is an industrial-grade remote BAI acquisition and control module, which provides passive node functions such as switching acquisition, tracking intelligent electrical output, and high-frequency counter. Multiple modules in this series can be used for bus networking, so that the IO points can be flexibly expanded. The module can be controlled via remote commands.

The module adopts industrial components, 10-30VDC wide voltage input, can work normally in the range of -30 60, and uses RS232 and RS485 communication methods to interact with the host computer.

The speed of the disk is undoubtedly the biggest bottleneck in the computer system, so when the disk must be used and want to improve the performance, people have come up with a compromise solution to embed a high-speed memory in the disk to save frequently accessed data to improve the reading and writing efficiency, and the embedded memory is called the cache.

1. Generalized: The CPU exchanges communication with other devices, and the information storage needs an interface to complete. The interface of different devices is different, which is called an IO interface.

2. Narrow sense: the speed of the disk is undoubtedly the biggest bottleneck in the computer system, so in the case of having to use the disk and want to improve the performance, people have come up with a compromise solution to embed a high-speed memory in the disk to save frequently accessed data to improve the reading and writing efficiency, and the embedded memory is called IO card.

Summary. Hello, you only need three steps to choose an IO card. 1.

First, count the various IO points of the on-site control equipment, and then add a certain number of spare points as needed; 2.Consult the manual of the system used, and find out the actual number of various IO cards (for example, the DI of JX-300XP is XP363, which is an 8-channel contact type switching input card); 3.Division.

Convert the number of points into the number of cards (note that if you can't round up, then you generally need to increase the number of cards, not reduce the number of points, otherwise you may not be able to meet the needs of the system).

Folded the points into the number of synthetic cards (note, if it can't be rounded, then the number of cards should generally be increased, and the number of points cannot be reduced, otherwise it may not meet the needs of the system).

I chose an IO card and it doesn't connect with the app.

Previously, this app was connected with the B product limb with the round card IO card, and the seller pie now has no B brand IO in stock. After I switched to a brand A IO card, the program did not communicate with the IO card.

1.Hardware driver installation first determine whether the hardware driver is installed in the computer management 1, make sure that the gold finger of the board is clean (clean the gold finger with an eraser), and install the card in the computer slot, 2, update the board driver, please refer to the method of installing the driver in the manual for installation. 3. Reinsert and remove the card, update the board driver 4, change the PCI slot or PCIe slot test, change the card to test the filial piety of the mold, change the computer test 5, If you still can't recognize the card after the above attempts, please contact the business code quietly and send the card back to the company for processing.

Administrator permissionsIf the card number appears in the open program is a very large number, please consider whether you have obtained administrator permissions to run directly when you use win7 and above versions of the system. When executable a program, you need to right-click on the program and select "Run as administrator", or use other methods to obtain administrator privileges, and the result of running the program is normal.

This app is not compatible as a result.

The program is not compatible, can you elaborate?

If the program is not compatible, this will not succeed pro.。

This one has to be changed back to the original brand.

Or you can find a second-hand original brand and replace it.

How can I make the program compatible with the new brand?

1. First of all, take any software as an example, and right-click to enter the properties of the software. 2. Switch the pop-up properties window to the compatibility panel. 3. Check "Run this program in compatibility mode" under the compatibility surface filial piety tong board and select this program to be compatible with hidden windows, check "Run this program as administrator" and click on the app to save the settings.

What part of the program do I need to change?

Fix your entire program.
