Common Opcclient and Opcserver software recommendations for OPC testing

When you are doing OPC communication, you often encounter two situations:

1) When using a opcclient to connect multiple opcserver on a remote computer on the same computer, one of the opcserver is found to be unobstructed, but the other opcserver do not work anyway. Do not know how to locate the problem? 2) Multiple manufacturers of opcclient connected to the same computer on the opcserver, found some opcclient pass, some do not pass, some can obtain data, and some can not get data. Based on the above situation, will always be commonly used opcclient and Opcserver recommended several, for everyone in a rainy days. Not the best, but probably just right! 1. OPC DA Client Recommendation: The recommended reason (this standard represents only personal opinion): 1) Single file, easy to carry, no installation, green environment. 2) adhere to the OPC standard, stable. 3) function does not need much, but the applicable function has one or more. Recommended first: OPCClient.exe put it in the first place is not how good, but 100KB volume, single file, also very in line with the OPC standard, so is a super-portable opcclient. Second place recommended: Matrikon Company's opcclient. Very good one opcclient, standard, stable, single file, communication process information is also rich, I prefer to use it when creating an OPC group, define either synchronous or asynchronous way to verify that the remote computer's OPC configuration is correct. The disadvantage is the big point, more than 2M. Recommended Third: Kepware Company's opcclient function is very strong, standard, stable, log information is very rich, the most recommended feature is to support the Opcserver in the name of the condition filter, support the import and export of the point table, support automatic import opcserver all points, According to the point table to identify better bad points, sorted by column, it can make up many of the domestic configuration software cannot traverse the function of Opcserver point table, can not filter the function of Opcserver point, can not recognize the function of bad point in Opcserver. The disadvantage is non-single file. In fact, there are many other very good opcclient software, you are welcome to share the recommendation. 2. OPC DA Server Recommendation: The recommended reason (this standard represents only personal opinion): 1) Still single file, easy to carry, no installation, green environment. 2) still adhere to the OPC standard, stable. 3) can simulate most common application scenarios and data, such as various curves (trigonometric curve, etc.), various data types, various types of failure, this one in most cases with the 1th is the conflict, So basically there are several opcserver recommended first: Knight.opcserver simple, or simple, single file run up everything has, 148KB, very suitable for simple testing. Recommended second place: MatriKon Company's opcserver simulator simple, single-file registration, a variety of data types, various point types (read-only, write-only, read-write points) have, a better point is, if you want to do large-scale testing, 100,000 points, Then just add any name to it's random, Opcserver will automatically give you the corresponding test points, or random number changes. Recommended Third: Kepware Company's Opcserver originally did not want to recommend, because this is a commercial software, need to spend money to buy license, but Kepware Company's opcserver need to spend money is not opcserver itself, but the acquisition drive. But the Kepware company's Opcserver provides a cost-free simulation drive, used to test it is kill anyone good thing Ah, the third reason for the recommendation is that it is the man.disadvantage is too large, not simple, high learning costs. But in order to meet the OPC products such as various tests, it is really the best choice. As it is commercial software, I do not provide, you go to its official website can be downloaded, do a good job of the tens of thousands of-point test project needs to find me. The OPC test software recommended in this paper: Baidu Network disk
