Hello hbosquemx; First, since you don't mention the family of S7 controllers you will be using after the conversion, the reply I am giving will be based on S7-300 modules; but info on the S7-400 modules is available on the same link. Basically, the answer to your problem is that you cannot use S5 modules on a S7 rack. If you are planning some full hardware conversion, you should look into removing all traces of the IP2xx modules and associated function blocks in the S5 program before conversion, and selecting appropriate S7 modules to do a similar job in your new program; this would be the easier path, the FM hardware and firmware would be compatible with the new CPU, there would be support for the positionning and counting functions from Siemens (S5 modules are now past support phase) and replacements would be much easier to come by. And they come with their own dedicated S7 functions to ensure their operations with S7-300or S7-400 CPUs. IP246: positioning module could be replaced by: FM 353: positioning module for stepper motors IP281: counter module could be replaced by: FM 350: single-channel fast counter up to 500 kHz FM 350-2: 8-channel counter, up to 20 kHz per channel https://www.automation.siemens.com/simatic/regelsysteme/html_76/produkte/sb-fm357.htm Hope this helps, |

No. There are no automatic conversion tools available. You will need to do this part manually. |

Hello Hbosquemx; There is no single compatible function block for such a conversion. You have to install the new FBs that come with the new modules in your new Step 7 program, converted from the S5 program without the IPxx blocks. Which means you have to look up the manuals for the new modules and study them, as a first step. For the FM 450: -Getting Started: http://support.automation.siemens.com/WW/view/en/5574978 -Installation and configuration: http://support.automation.siemens.com/WW/view/en/1118412 For the FM 453: -Getting Started: http://support.automation.siemens.com/WW/view/en/2124818 -Manual of the servo/stepperpositioning module: http://support.automation.siemens.com/WW/view/en/2123608 The Getting Started manuals are a good place to start, they are short, general, and give a good overview of the installation, parameter assignment and functions required to make the module work. The other manuals are more heavy reading, but they cover most details of the workings of the modules. Especially important if you have to chose different configurations or applications with these modules. There are many documents available on every Siemens module on their support page: FAQs, Application notes, downloads, updates... can be found on the Product Support link at the top of this page. Simply use the Search window in the support page to look for inofrmation on the FM 450, for example. And of course on this forum you will find other control people who have had experience with these modules, and who can help you out when you face specific problems. Suerte y paciencia, Hope this helps, Daniel Chartier |
