OPC Client

OPC Client is a lightweight software application whose purpose is to help you establish a connection with an OPC server in order to receive and send data, messages and indications.

Portable utility

The tool can be run directly on your system without having to follow the steps included in an installation process. Plus, it doesn’t leave any entries in your Windows registry so you can open it without administrative privileges. You may copy it on any USB flash drive or other devices and take it with you.

Simple looks

The tool adopts a clean and intuitive layout that doesn’t hide any intricate configuration settings under its hood. Everything is kept simple and clear, so even rookies can learn to configure the program in no time.

OPC sending/receiving features

Working with this utility proves to be a child’s play, as you only need to enter the address of the remote OPC server and click on the ‘Connect’ button.
OPC Client splits the main window into several smart panes that give you control over the connection process. You can check out a list with the local OPC servers, connect to the selected server, add and read items, view server information, as well as get detailed information about each item, such as name, current value, time stamp, quality and type.
Last but not least, the application records the cycle in seconds and number of items, and lets you enter the value of the cycle duration to read/write to a database (as a multiple of 1 second), disconnect from the database, and open the log file which displays information about the entire connection process and possible errors (the log is automatically saved to plain text file format).

Conclusion

All in all, OPC Client delivers a straightforward software solution for helping you communicate with an OPC server, and is suitable for all types of users, regardless of their experience level. On the downside, it hasn’t been updated for a while so errors may appear if you run it on newer operating systems.
