In Siemens’ stepwise model for migration execution, #HMI is usually the primary concern for end users when it comes to #migration projects, and typically has the shortest lifecycle of all system components, and it involves the least overall risk. Many end users want to keep their existing HMI consoles as long as possible, and this requires a planned transition where the new #SIMATIC PCS 7 OS HMI consoles and workstations can run in parallel with those of the legacy system in order to help the transition for operators. Aside from HMI connectivity, Level I of Siemens’ migration solution also includes HMI conversion (Moving tag databases and graphics from one HMI platform to another), and enhanced batch management.
One of the services Siemens provides is the ability to migrate controller configuration from #APACS + to SIMATIC #PCS7. This option is available for some Siemens systems and is in development for other legacy systems. Since all controller databases consist of function blocks with input and outputs, Siemens is able to translate the legacy control configuration and place it in native PCS 7 control code. Since the old code is reproduced in SIMATIC PCS 7, it reduces training costs when migrating to the new system
APACS+ MTA termination migration to PCS 7 IO.
A universal cable with perfect connection to the APACS+ MTA’s, field cutover in seconds to new IO is what this solution offers. The Siemens MTA cable is offered in 3, 8, 15 and 30 meter lengths with a perfectly matched connection to your MTA and the option for direct connection or via terminal strips (with fusing) to your new PCS 7 IO card. We can further simplify the connection between the PCS 7 IO card and the terminal strip with a pre-assembled, tested and labeled TOP connect wiring/termination offering.
This can also include updated drawings. The new IO and termination assemblies are designed and tested offsite to be an optimized fit for your installation. In this example we show a (32ch) 24V Standard Discrete Module (SDM) termination connected to a terminal strip and then a (16ch) DI and (16ch) DO PCS 7 ET200M IO cards on the left side of the rail.
The bottom (32ch) Standard Analog Module (SAM) is wired directly to the two (8ch) AI and two (8ch) AO PCS 7 ET200M cards on the right side of the top rail. The SAM module did not support HART, whereas the PCS 7 ET200M IO modules can. This now gives you easy access to the extended data and diagnostics provided from HART.
To cutover your system, just install your new IO panels onsite and the APACS+ termination MTA cabling migration takes seconds – just remove the old MTA connector to the APACS+ module and install the pretested and new MTA cable to your existing APACS+ MTA – thus connecting to your new IO – 32 channels migrated in seconds.
