What is being procured?

Scope of work

Language of the publication

ABB AC450 process controllers are in use at the Basel Waste-to-Energy Plant (KVA). These are no longer supported or maintained by ABB; therefore, they have reached the end of their service life and must be replaced. The controller replacement will be awarded in two separate lots:

- Lot 1: Necessary hardware for controllers and I/O stations, including interfaces.

- Lot 2: Software migration from existing AC450 controllers to AC800M controllers.

The migration of the old software must be carried out without modifying the process functions.

Scope of work of the lots

  • Lot 1 – Los 1 Hardwareshow

    Five AC450 controllers with node numbers 22, 32, 41, 42, and 51 will be replaced. New ABB AC800M PM866AK02 controllers will be installed. The non-redundant AF100 buses currently in operation that connect to the S800 peripheral cluster must be replaced with redundant Profibus-DP connections, including the S800 Profibus-DP header modules.

    Furthermore, the existing connections to third-party peripherals (boiler safety systems, auxiliary burner control, crane system, turbine, and various touch panels) must be implemented on the AC800M. This applies to the serial interfaces using 3964(R) and RK512 stack as well as Modbus RTU. These connection types are to be retained with the AC800M for the time being and replaced with Profinet at a later date, depending on the situation. The necessary Profibus DP gateways must be procured and implemented.

    Details of Lot 1
  • Lot 2 – Los 2 Softwaremigrationshow

    The existing AC450 AMPL code (Advant MasterPiece Language) is based on a slightly modified ABB APC library. For the migration, the already installed ABB APC AC800M library must be used. This library is provided exclusively for this project.

    The AMPL code may be automatically translated into function blocks. However, the functionality of the old code must not be altered. The AMPL code must not be provided to third-party companies for translation. The newly translated AC800M code must continue to use the existing database names, so that only the AC800M-specific signal identifier may be appended as a suffix. Variable names in the code must be retained.

    The existing MB300 interface must remain in place and continue to serve, as before, for cross-communication with the other controllers. The transmission scheme must be adopted on a 1:1 basis so that no adjustments are required on the other controllers. The most recent migration of Node 21 has demonstrated that this is feasible.

    A dedicated 800xA AC800M engineering station is available for on-site preparation and commissioning. Commissioning must be performed on-site.

    In particular, the migration also includes the following aspects:

    - Process screen adaptation

    - Sequences

    - Trends

    - Interfaces to third-party devices
