Olink ore pool

1.

After the computing power of the whole network has been improved to a certain extent, the probability of getting rewards is too low, so that some geeks on "bitcoin talk" can develop a method that can combine a small amount of computing power and operate jointly, and use this method to build websites

in this mechanism, no matter how much computing power an indivial miner can use, as long as he participates in mining activities by joining the mine pool, no matter whether he has successfully mined effective data blocks, he can get a small amount of bitcoin reward through his contribution to the mine pool, that is to say, many people cooperate in mining, and the bitcoin reward is shared by many people according to their contribution

as of January 2019, the top five bitcoin pools in global computing power are btc.com, pool, antpool, flush pool, and f2pool. At present, about 70% of global computing power is in the hands of Chinese miners

extended data:

handling charge:

bitcoin miners will charge a small amount of fees for most transactions, the main purpose of which is to prevent people from sending a large number of boring small transactions and wasting network resources. At present, most of the handling charges for each transaction are & T 3647; 0.0001/kb (0.0001btc / KB). In fact, after 0.9.0, the default handling charge will be reced to & 3647; 0.00001/KB(0.00001 btc/KB)

because the amount of data occupied by most transactions is less than 1 kilobyte, generally speaking, the amount of data is less than 3647; 0.00001 (0.00001 BTC / KB) is enough. At the same time, in the future, when the bitcoin block rewards are less, the service charge will become the main source of miners' income, and the service charge of bitcoin will be related to the number of bytes occupied by the transaction

at present, the calculation standard of service charge in bitcoin system is not mandatory, so users can not give any service charge when the transaction is in progress

however, most miners usually give priority to the transaction with higher handling charges when building data blocks, so that they can get higher remuneration when mining is successful. Therefore, the transaction without any handling charges may take a long time to be processed and incorporated into the blockchain

in addition, e to the block capacity limit of 1MB and the recent increase in bitcoin transaction volume, the handling charges have increased significantly, and the waiting time for the transaction to be confirmed has also become much longer

IO link is not a system, but one of the main real-time Ethernet protocols in gateway communication

the mainstream protocols of real-time Ethernet include: IO link, CC link, ie, Modbus / TCP, AS-Interface, SERCOS, EtherCAT, PROFINET, Ethernet / IP, Powerlink, etc. the mainstream protocols of Fieldbus include: PROFIBUS, DeviceNet, CANopen, CC link, INTERBUS, ControlNet, componet, etc

extended data:

the significance of gateway:

all kinds of protocols have their own advantages and disadvantages, and the new generation of mainstream protocol is the continuous improvement and supplement of the previous protocol. Due to the different manufacturers, proction time and application occasions of various devices, communication between different devices will encounter many obstacles, just like a person who only speaks Chinese meets a person who only speaks German and needs a translation or intermediary language, which is often common English

the physical layer structure of real-time Ethernet is the same, and RJ45 is used. Therefore, for real-time Ethernet, the hardware to realize various protocol conversion is the same gateway, but the difference is that users only need to download the corresponding protocol

5. Dlink has heard of it, but olink hasn't. Dlink Ethernet optical fiber transceiver is Youxun Ethernet optical fiber transceiver. Guangzhou Huipeng is the general representative of dlink in South China.

6. Fssb is the serial high speed bus of FANUC system and the communication channel between CNC and servo driver. Generally, it is optical fiber communication. I / 0 link is the link between CNC and external input and output, generally connected with signals such as coolant, machine lighting, tool table rotation, cycle start, etc. Controlled by PMC.

7. Hello, I'm glad to answer your question here:

I / O interface,

8. When VC regenerates the EXE file under the debug directory, it needs to delete the original EXE file first. But because the file is running or locked, it can not be deleted, so lnk1168 error appears. You can close the original EXE file first and then delete it manually (if you can't find the window, just see if there is this exe running in the task manager, and force it to close if it exists). If the deletion fails, use 36o in the right-click menu to release the occupation.

9. 1. There are two kinds of moles: 8 discrete inputs and 8 I / O moles
3. Connection of M8
4. Expansion port is used to connect another M8 I / O hub of the same type
