Wrong Monitoring Time

The OIS parameter supervision directly impacts the behavior of the fallback function, in other words when OIS assumes responsibility. Only configure faster response times in the OIS in exceptional cases. Contact the Siemens service technician or hotline in this regard.

If connections are frequently closing between Siveillance Control and OIS in case of large systems, faster response times can be configured in the OIS. The default response time for an action is five seconds: OIS waits for five seconds for a telegram response before it closes the connection:

  • The current OIS version has been used.
  1. Start OIS Tools on the OIS computer.
  1. Insert the supervision parameter for the OIS connection and set the value to 10 seconds.
  1. Save the change and upload the file.

Unable to Connect to OIS

The connection to OIS cannot be established, because OIS is not available.

The following causes are possible:

  • The root certificate is invalid, because either localhost or 127.0.0.1 has been used when creating the root certificate in OIS Tools. For more information on how to set up OIS Tools, refer to: Setting Up OIS Tools in Browser in Subsystems Integration with OIS.
  • The root certificate is invalid, because the domain name has not been specified when creating the root certificate in OIS Tools.

To establish a connection with OIS, a new root certificate needs to be created in OIS Tools and imported in Siveillance Control:

  • The current OIS version has been used.
  • You are logged in as root user.
  1. Open a terminal window.
  1. Enter the following commands:
    #ois certs create
    #ois web restart
  1. Open Firefox and start OIS Tools on a Windows PC.
  1. Enter the following link in the address bar in the format:
    http://[ip address]/#/home
    Example: http://10.1.3.15/#/home
  1. Click Generate.
  1. Follow the steps described in Setting Up OIS Tools in Browser and afterwards in Starting OIS Tools in Subsystems Integration with OIS.
  1. To import the certificate to Siveillance Control, refer to: Importing the Certificate to Siveillance Control Servers in Subsystems Integration with OIS.
