Take a look at this forum post first: asynchronous parameter write in a Sinamics S120. |

It looks like the S7-FBs in the linked item is for legacy Step 7 and not for the TIA Portal which is required for the s7-1200 plc family. |

Hello, the acyclic communication ispossible with FB286. The cyclic communication for speed axis with telegram 1 is possilble with FB285 and for positioning axis (basic positioner) with tel 111 you can use FB284. By installation of STARTDRIVE V13 you will get it installed automaticaly - with V12 SP1 you can download it here " DriveLib_S71200_V12_SP1 ": http://support.automation.siemens.com/WW/view/de/68034568 For other telegramms you can use DPWR_DAT and DPRD_DAT for cyclic communication. Helpful are the UDT`s for all standardtelegramms: http://support.automation.siemens.com/WW/view/de/82841762 Regards Zako |

What is FB286? In tia portal and s7-1200, all instruction blocks have names, not numbers. I find it troubling when the legacy step 7 and tia portal worlds collide because people with vast years of experience know the FB #'s, and my relative newness to tia portal and siemens knows the instructions by name only. I am trying to perform acyclic comms for parameter read/write access on an s120 sinamics drive via profibus. It seems like a straightforward thing, but finding the *right* hardware ID and drive object has been troubling. I get an error when trying to read 2 parameters. |

Hello, have you checked my link? There you will find the following document: http://cache.automation.siemens.com/dnl/zI/zIzMjIzMQAA_68034568_DL/SINAMICS_Bausteine_TIA_PORTAL_V12_SP1_en.pdf You are right, normally in TIAP you will use "names" but also in the documention you will find a FB- number (maybe for users like me, which prefer numbers) : SINA_PARA (FB286) |

Zako, I appreciate the responses and details. Thank you for that. What I do not understand is *what* telegram to drop to get a valid hw_id to use in my read request WRREC call. I am using an s120 with a vector drive in drive object 2. |
