Answer question
800xa OPC string communication
For communication between our 800xa DCS controllers and MES system we also communicate strings. We notice that communication of strings is much slower than the simple datatypes. Strings have their own subscription rate in 800xa which is normally set at a subscription rate of about 10 seconds or slower. Why is the default value so slow and what will happen if we set it to 500ms (e.g.)? After all strings are nothing more than a series of bytes.
