Requirements and installation

Requirements

• Correctly installed WinCC OA version 2.12.1 or higher.

• The IEC 104 and IEC 101 drivers require a license.

For information on the supported platforms for the IEC driver see Supported Platforms of the most important Drivers.

A redundant WinCC OA system with 2 IEC101 drivers in unbalanced mode on one bus does not work at the moment, because both drivers want to be the master and no communication can be established! For a normal behavior in case of redundancy each driver must run on its own bus.

Installation

Standard installation of WinCC OA version 2.12.1 or higher is required for using the IEC driver.

Further details on installing WinCC OA are given in the Installation chapter of the Online Help.
