First, it is necessary to install and configure Axxon One, with which integration is required. For more details, refer to the Axxon One Documentation:

• Installation of Axxon One
• Configuration of Axxon One

Additionally, it is necessary to install the Axxon One Client (see Installing Axxon One) on the computer where the Axxon PSIM Server is installed and where integration will be configured. No configuration of the Axxon One Client is needed; it only needs to be installed. If the Axxon One Client will be used on multiple computers within a distributed system, it must be installed on each of these computers in the same path (see the Path parameter on the Creating and configuring AxxonOne manager page).
