TASK

  • Functional one-to-one conversion of turbine control from S5-115U to S7-400
  • Conversion of the existing interface between the turbine control and turbine regulator from TTY 4-20mA to Profibus-DP

DESCRIPTION OF DELIVERIES AND ACTIVITIES

SOFTWARE PLANNING

  • Working out the process functions and creating graphical P-FUPs
  • Development of our own S7 drive modules to replace the existing drive modules with the objective of transparent and open-source program structure in S7-FUP
  • Partial conversion of the system-specific program sections from STEP 5 to STEP 7
  • Programming of the process functions using drive modules developed by INP
  • Adaptation of the WinCC interface

HARDWARE PLANNING

  • Configuration of the S7-400 hardware
  • The existing S5 front-panel connectors were retained with the help of Siemens peripheral adapters in order to minimize the installation time and thus reduce the plant downtime
  • Documentation of the hardware planning in EPLAN Electric P8

WORKS TEST

  • Carrying out the works test in INP Deutschland GmbH
  • Installation and system commissioning of the S7-400 hardware to be supplied
  • 100% signal test (input channel to WinCC) using our own test cabinets
  • Test of the Profibus interface to the turbine regulator
  • Functional test of the software by simulation
  • Logging of results

Installation

  • Removal of the existing S5 controller
  • Installation and new wiring of the new S7 controller in the same location

Commissioning

  • Writing the commissioning sequence plan
  • Carrying out commissioning under our own responsibility
  • Logging the results of the individual commissioning steps
  • Customer acceptance

RESULTS/CHARACTERISTIC VALUES

  • Improved functions adapted to the customer's wishes by in-house development of the drive modules
  • Reuse of the S5 front-panel connectors and carrying out the works tests made it possible to reduce the commissioning time and thus the plant downtime to only four days
