About Profibus DP
Thread Content
I would like to ask the experts: The field instruments use the traditional wiring method for HART communication, while Siemens’ quote specifies that the DCS system will use SPPA T-3000. Part of its architecture relies on Profibus DP for communication. Is this acceptable? Is it necessary to use Profibus PA as well? Or should the communication method after the I/O cards be determined based on the specifications provided by each DCS manufacturer?
It seems that your inquiry version of the specification sheet does not specify this in detail. The manufacturer can recommend options, but the final decision is up to you. If you are not interested in PROFIBUS, it is entirely possible to specify SIEMENS and switch to the HART protocol instead. Take into account the project budget and the overall plan as a whole.
I didn’t quite understand the SPPA-T3000 – the floor above and the floor above that. Currently, to manage Hart smart meters with the T3000. It is needed. 1. Use AI AO cards that support Hart. For example, SM331 7TF01-0AB0. SM332 8TF01-0AB0. 2. The instruments also need to support Hart. Of course, that’s obvious, haha. 3. If there are isolators and safety gates between instruments, actuators, etc. and AI/AO cards, then those isolators and safety gates must also support Hart. 4. The Io station of the T3000 uses ET200M. The interface unit IM153-2 of the ET200M must also support Hart. --Of course, all new versions are supported. 5. The ET200M uses Profibus to connect to the controller head of the T3000. However, it cannot be connected to the Profibus DP interface integrated in the 41X-4H CPU of the T3000. The intelligence is connected to an additional CP554-3 Profibus DP interface module. As for the specific reasons, there’s no need for further explanation; just remember that currently, the 41X-4H model requires a Hart card module, and it can only be used with the CP443-5. 6. The PDM software needs to be installed on the T3000 server. 7. It’s basically okay. 8. If you are purchasing Yokogawa or Rosemount Hart instrument actuators. Then you can ask the manufacturer for the EDD file of the instrument. Or download it from the website. Then import the EDD file of the instrument into Siemens’ PDM software. So at this point, the T3000 can not only configure Siemens Hart instruments, but also Yokogawa and Rosemount Hart instruments. 9. Over
