Dashost.exe windows 8 - responses to the issues
What is dasHost EXE?
dashost.exe is used by the Windows OS to pair hardware devices with your PC. For example, if you need to pair a new mouse or webcam with your PC or notebook dashost.exe does the pairing to make it work. dashost.exe stands for Device Association Framework Provider Host.
Okay folks, as requested, we're going to go over a number of super useful programs that Microsoft made itself for Windows, and perhaps even one of the most useful software suites ever made isn't actually included with Windows.
So if you didn't know about it, you are really missing out on something. There are way too many programs to go over in a article, and some of them are either outdated or not very useful, so I've got to go over what I think is the coolest and most useful programs in the Sysinternals suite. And of course the link to get it is in the description.
Here we go. First we have the 'Process Explorer'.
Should I allow dasHost EXE?
The genuine dasHost.exe file is a software component of Microsoft Windows by Microsoft. DasHost.exe runs the Device Association Framework Provider Host that connects and pairs both wired and wireless devices with Windows OS. This is an essential Windows file and should not be removed unless known to cause problems.
How do I disable dasHost EXE?
- Open Task Manager.
- Locate from the Processes tab the dasHost.exe task that's slowing down your computer or behaving erratically. It's called Device Association Framework Provider Host.
- Right-click the task and go to End task.
- Restart your computer.
What is Device Association Network?
Device Association Framework Provider Host is an official Microsoft core process that runs under the LOCAL SERVICE account. The process serves as a framework for connecting and pairing both wired and wireless devices with Windows.
Device network? Not familiar with it? Well, let's take a journey through the automation world of DeviceNetDeviceNet is an application level protocol used in the automation environment.It is a communication tool that allows you to logically communicate between a PLC (Programmable Logic Controller) and many control devices.
B. Motors, conveyor belts, flow meters, level sensors, etc. Instead of the PLC communicating directly with discrete I / O modules, it communicates through a DeviceNet scanner.
It was originally developed by Allen-Bradley, a brand of Rockwell Automation, and they decided to share this new technology with others and make it an open network.

DeviceNet is now managed by the Open DeviceNet Vendors Association or the ODVA, one Organization that develops standards and enables third party vendors t The DeviceNet network protocol follows the Open Systems Interconnectionor OSI model, which uses seven layers which are physical, data link network, transport session, presentation and application. It is based on the Common Industrial Protocol or CIP and uses the three upper layers of CIP, starting with the session, while the lower 4 layers have been adapted to the DeviceNet application The physical layer consists of a combination of cables, nodes, taps and terminating resistors in A trunkline-dropline topology We will discuss these physical components shortly For the data link layer, DeviceNet uses the Controller Area Network or CAN standard, which handles all communication between controllers and devices.
Network and Transport Layers of DeviceNet Connect to the device using connection IDs for the nodes, which consist of a device's MAC ID and a message ID The valid range of node addresses is 0 to 63, making them a total of 64 possible connections The advantage of Connection IDs is that it allows DeviceNet to identify duplicate addresses by looking at the MAC ID and signaling the user that it needs to be repaired Now that we have looked at the structure of the DeviceNet application layers So let's look at the part of DeviceNet we can get our hands on The genius behind DeviceNetis that has joined the power and signal in one cable, saving money and reducing the need for multiple cables that take up more space 5 types of cables, three of which are round and two are flat. They are thick round, thin round, class 1 round, KwikLink Flat and KwikLink Lite Flat.You can use the round (thick or thin) cable for either trunk or stub lines, the flat cable for trunk lines, and the class 1 stub cable for stub lines.
They all use twisted pairs of wires, one pair for the 24vdc supply and one pair for the signal, there is also a shield wire that is used in the grounding process, the cable you choose for your application which is mainly based on distance as there are certain length restrictions These distances are measured by two variables: Trunkline distance and total length of the DroplineDeviceNet data rates are 125, 250 or 500 kilobits per second.The longer the required length results in a slower data rate and vice versa.The thick round cable has a maximum length of 1,640 feet at 125 Kilobits per second up to a maximum length of 328 feet at 500 kilobits per second 'Thin' round cable has the same maximum length of 100 feet for all three data rates of 125,250 and 500 kilobits per second.
The KwikLink flat cable ranges from 1,378 feet at 125 kilobits per second to 246 feet at 500 kilobits per second. The 'KwikLink Lite' flat cable ranges from 1148 feet at 125 kilobits per second to 180 feet at 500 kilobits per second. Since there are no predetermined cable lengths.
You can connect the ribbon cable anywhere on the line, which makes this choice great for device placement Trunkline requires a terminating resistor of 121 ohms, 1 percent, 0.25 watts, or more at each end of the trunk that runs directly through the signal lines ( blue and white) is connected. The terminating resistors reduce electrical noise and without them in the right place the DeviceNet will not work properly.
The stub lines connect the devices to the exchange line and the selected data rate determines the total length of the stub line. The biggest limitation for a stub is that the maximum cable distance from any device to the trunk is 20 feet, and the maximum total drop length for any data rate is 512 feet at 125 kilobits per second, 256 feet at 250 kilobits per second, and 128 feet at 500 kilobits per second. Once again, it shows that the higher data rates give you shorter distances your network can reach, and lower data rates give you wider possibilities.
You can connect the trunkline to the devices using several types of taps and connectors. Devices can be connected to these taps and connections; they can be connected directly to the trunk line or by branching or chaining to one another. This choice affects the calculation of the total drop length as the direct links are considered zero drops, while branches or daisy chaining contribute to this calculation.
These connections are specifically designed to allow the exchange of devices without disrupting the network. Now that we have the physical network in place, let's talk about the software side which is an interface to configure our DeviceNet network. Allen Bradley developed RSNetworx for DeviceNet to be able to map and assign addresses to all devices on the network RSNetworx for DeviceNet uses either a graphical or spreadsheet layout to map the network and then the configuration is set up in all devices and then downloaded to the DeviceNet scanner.
The DeviceNet scanner is a piece of hardware that is located in the PLC chassis and over the backplane of the chassis. DeviceNet uses Electronic Data Sheets (EDS), which are simple text files that contain all the information needed to identify a device and to help with commissioning in the network. The advantages of DeviceNet are low costs, wide acceptance, high reliability, efficient use of the network bandwidth and the power available in the network.
The disadvantages of DeviceNet are limited bandwidth, limited message size and maximum cable length. In many documents it is stated time and again that 90 to 95 percent of all DeviceNet problems are one of two things: a cabling problem or you do not have the correct EDS file registered in RSNetworx for DeviceNet. This makes DeviceNet a great network when you look at the bigger picture.

Where is the dashost.exe file in Windows 8?
The correct file location for dasHost.exe file is C:WindowsSystem32dasHost.exe. If you have found this file on any other location, especially under program files, then it might be a virus. Windows 8 and its successor operating systems need this file for proper working.
How big should a dashost.exe file be?
Under the Details Right-click the suspicious dasHost.exe process and then select Properties. On the Properties window, look at its size. The size of the real dasHost.exe file should be less than 100KB. If the size of the file is more than that number (especially the size is several megabytes), you need to delete it as soon as possible.
