A customer has expressed interest in developing a PROFINET IO device over APL and requires guidance starting from scratch. As part of my consulting services, I am assisting this customer with determining the necessary investment for the PLC IO system. While I am well-versed in factory automation, my knowledge in process automation is more limited, so I would appreciate any advice. I understand that developing a PA Profile compliant device will require the proper testing tools. Simply using a PLC may necessitate developing a PLC program implementing the FB in ladder logic. While this is theoretically possible, in practice it may prove challenging, especially for those with limited proficiency in PROFIBUS PA, like my customer and myself. Therefore, I need to provide a Bill of Materials (BOM) outlining the required components. Is the following list accurate and complete? 1) APL switch 2) License for SIMATIC Process Control System PCS 7 SIMATIC PDM Readme V9.1 3) License for TIA Portal v19 4) An S7-1500 PLC, preferably with a PROFIBUS DP interface for future compatibility. Would you be able to recommend a specific part number? Thank you for taking the time to review this information.
If you're looking for helpful information about device certification and PA Profile info, the link below from PI North America's Development website may be useful. It also provides details on reference implementations that you can test with. While Simatic PDM is commonly associated with Simatic Manager/PCS7, its compatibility with Tia Portal is less clear. It's uncertain if 1500/Portal supports APL, as it is a relatively new development. However, there is an indication that APL is supported for PCS7. For additional assistance, you can visit the SIOS support page on Siemens' website.
Thank you for your interest and support. The TIA Portal V19 now has the capability to support PA profile GSDML files, which includes the advanced physical layer necessary for developing PROFINET IO devices. When it comes to choosing a PLC for your project, whether using standard RJ45 Ethernet or APL, the S7-1500 is likely to be the top choice for many end-users. With the inclusion of the PA Profile functionality, utilizing Simatic Manager/PCS7 as your tool of choice is highly recommended. While it is theoretically possible to create your own function blocks in TIA Portal, using Simatic Manager/PCS7 provides a convenient off-the-shelf solution. Additionally, having a license for Simatic Manager/PCS7 can be advantageous for after-sales support. If you are experiencing delays in responses from the local Siemens team, it may be helpful to consider these factors when deciding on the best course of action for your project. Thank you for your feedback and support.
I may not be able to assist directly, but I can share my experience using PDM with PCS7 for configuring and installing Profibus PA devices. Typically, the PDM software is installed on an Engineering Station alongside Simatic Manager. Begin by accessing the hardware view, adding the Profibus card to the rack, and importing device files. After dropping your device onto the network, it should automatically appear as node 126 (note that this may vary for Profinet). You will then assign memory addresses to the device before going online to adjust the node address and restarting the device. It's worth mentioning that 3rd party devices are available for setting node addresses, but they can be costly and not commonly found in facilities. Once you have the correct node address, you can proceed to configure the device online. With Profibus devices, scaling is handled within the device itself, eliminating the need for traditional channel drivers in the CFC. Keep in mind that PDM can be sluggish. In PCS7, the next step would involve constructing a CFC and assigning memory addresses, rendering a "custom" FB unnecessary.
Thank you, Ken, for the helpful information. PROFINET IO over APL represents the future of intrinsic safety compliant devices, eventually replacing PROFIBUS PA. The concept involves transferring all PROFIBUS PA device functionalities to Ethernet APL in terms of the physical layer, utilizing PROFINET IO for the protocol, and implementing the PA Profile for the application. Therefore, if a customer is looking to create a PA Profile compliant device, this tool is essential for development.
Your initial list is a good starting point, but you may also want to consider including HART communicators. The customer may get certain devices which require HART functionality. As for the S7-1500 PLC, I would recommend the CPU 1512SP F-1 PN (6ES7512-1SK00-0AB0) due to its efficient and flexible application capabilities. You also might want to consider not only the initial hardware and software investment, but also costs associated with training the staff to operate and troubleshoot the new system. Keep in mind, process automation usually requires a higher initial investment but typically provides more benefits in the long run as compared to factory automation.
Your list seems to be on the right track, but there are a couple of things worth considering as well as a few potential alternatives. The S7-1500 PLC with PROFIBUS DP interface is indeed a viable option for future-proofing the system; however, I'd recommend Part No.: 6ES7 515-2AM02-0AB0 due to its advanced integration capability. And don't forget to include Hardware Support Packages (HSPs) for smooth integration into the TIA portal and GSD files that are mandatory for device integration to the PCS 7 systems. In terms of APL Switch, it can be a good addition for this setup, but do evaluate if a Barrera or Segment Coupler would be more fitting for your use case. In essence, it's about balancing your customer's upfront cost versus long-term maintenance and potential upgrades down the line. Lastly, remember, while the software is essential, so too is your client's potential need for training on this new system, so it could be wise to factor that into the budget.
Your groundwork seems solid and your list mostly accurate, but you might want to consider adding a PROFIsafe license, too, especially if your client's operation involves hazardous environments. This will ensure the safety of communication in case of emergencies. For your S7-1500 PLC, the model '6ES7515-2AM01-0AB0' comes with PROFIBUS DP interface and it's generally well-regarded in the automation industry. Don't overlook training and ongoing support in your BOM. This can often be underestimated but it's essential when implementing new tech.
Your list provides a good starting point for the process automation journey. However, I would recommend investing in a PROFIBUS PA segment coupler and specialized APL IO modules bearing in mind the required communication speed and control logic. These can allow seamless communication between your PLC and the field devices. As for the S7-1500 PLC, I'd suggest the part 6ES7515-2AM02-0AB0; it has a built-in PROFIBUS DP interface. Also, don't forget about the need for training on the TIA Portal and process automation overall. Ultimately, the success of your project may largely depend on your understanding of these systems and your ability to adequately train your customer. Keep us updated on your progress!
It sounds like you're on the right track with your BOM, but I'd suggest adding a few key items to enhance the development process. Consider including a dedicated PA testing tool like a PA monitor for debugging and verification, as well as any necessary cabling and connectors for your APL setup. Regarding the S7-1500 PLC, I'd recommend the 6ES7512-1AK00-0AB0 model, which has the versatility you need for both PROFINET and PROFIBUS interfaces. It might also be helpful to look into any training resources or documentation specific to APL and PA profiles, as it could make the learning curve a bit smoother for both you and your customer. Good luck!
It looks like you’ve got a solid starting list for your BOM! In addition to what you've mentioned, I'd recommend including a robust testing tool like a PROFINET simulator or a dedicated protocol analyzer to handle your device's verification process effectively. For the S7-1500 PLC, consider the 6ES7522-1BL00-0AB0, which has the necessary capabilities for your setup and supports both PROFINET and PROFIBUS for future-proofing. Don't forget to factor in proper training materials or support resources for both yourself and the customer, which could really ease the learning curve with PA profiles. Good luck with the project!
