The OPC Server license has included the Modbus RTU and TCP communication drivers as well as OPC UA Client. You can select the license based on the number of variables to be exchanged with the field (TAGS). This allows you to purchase the Runtime license based on the real needs of the project.

By Tag we mean any variable “connected to the field” of type bit, byte, word, float and double / long 64bit, even if defined as a member of structures or arrays. The variables byte, word, etc. they can be “bet” internally to the single bit.

Connext has numerous communication protocols and, depending on the needs, it is possible to enable the desired “I / O Drivers” package among the additional driver packages.
