AEG PLC-Migration – Latest technology and protection of existing investments
Do you operate an AEG PLC system with the systems A120, Compact, A250, A130, A350 or A500? Then you can look into the future with confidence, because OHP offers, in addition to spare parts and new parts for your proven AEG PLC system, a cost-effective, reliable and long-term available option to upgrade your AEG PLC system to the latest state of the art.
With the OHP systems @120 and @250, new products are available which migrate the A/U devices from AEG/ Schneider into a new and long-term available automation and telecontrol series from OHP at minimized cost and time. The impressive advantage of this strategy is the cost saving by using existing peripherals such as I/O modules and KOS modules with existing wiring: Only what needs to be replaced is replaced.

Advantages of an AEG PLC migration to OHP @120 or @250
With AEG migration, your systems experience added value that is characterized by IEC conformity – IEC 60870-5-101 /-104 protocols, IEC 61131-3 programming – and the opening of the system for external expansion. As a rule, only the ALU and backplane need to be replaced, making the standardized IEC 60870-5-101 /-104 procedures with modern programming technology available under IEC 61131-3.
By using the existing KOS modules, there are elegant upgrade possibilities from SEAB 1F and SEAB 1W procedures to standardized IEC procedures.
- Retention of the existing AEG PLC I/O level
The impressive advantage of this strategy is, among other things, the retention of the existing I/O level. This eliminates high costs for new I/O modules during assembly and wiring as well as for documentation and training. This means that a modernization of the system can be realized with considerably lower and manageable costs and time expenditure.
- Carrying out a modernization during operation
The implementation of a modernization during ongoing operation can be calculated exactly, as there is no „point of no return“. If the system to be modernized has to be put back into operation at a certain point in time, the previous ALU and, if necessary, the basic subrack can be simply plugged in if necessary.
- Upgrade to modern programming technology and communication interfaces
In addition to the upgrade to modern programming technology and communication interfaces, the @120/@250 modernization of an existing A-device automation system provides added value that ensures the long-term use of the system.
- Added value through new standardized IEC 60870-5-101/-104 or Modbus procedures with modern programming technology under IEC 61131-3
Usually only the ALU needs to be replaced, making the new standardized IEC 60870-5-101/-104 or Modbus procedures with modern programming technology under IEC 61131-3 available.
- Elegant upgrade strategies from SEAB 1F and SEAB 1W procedures to standardized IEC procedures
By using the existing KOS modules, elegant upgrade strategies from SEAB 1F and SEAB 1W procedures to standardized IEC procedures are possible.
- Development of new technologies and extension of functionality by using modern components
- Long-term availability of all modules
- Further use of existing AEG PLC spare parts
