But there are often good reasons for choosing different approaches, for example by also using OPC. This was a decision that needed to be considered carefully, as there are a number of disadvantages; however, the benefits of the new OPC UA standard outnumbered its disadvantages by far.

Now, when you use zenon, you will be able to use the new OPC UA client. You will benefit from:
- strong and stable performance
- simple configuration, even for firewalls
- up to 256 bit encryption
- tamper-proof connection
- ‘eavesdropping’ protection

Standards such as OPC UA are the foundation for the openness of zenon –  a good reason for us to quickly deliver a well-engineered and thoroughly tested client to the market. After all, it is your decision whether you want to rely on communication that is based on international standards or on fast and direct connections – one will be better than the other for you.

At COPA-DATA we prefer not to prescribe one solution, but rather to use the benefits of different approaches. The large number of zenon communication protocols gives our users the freedom to go their own way. If you require a certain driver, you will get it. However, standards like OPC, IEC or SNMP and popular protocols like Modbus are the supporting pillars of zenon. do it your way!
