Hey j_bernaer, the OB_Begin block is part of the Basis Library, so you can find a description of the I/Os in the corresponding manual. Here is the link: https://support.industry.siemens.com/cs/ww/en/view/90683135 In a summary: SUBxIDxx is used for the DP master system and EV_IDx for the message numbers for ALARM_8P. You can find more information in the Chapter 5.36 (for V8.1) of the mentioned manual, which is about the OB_Begin block. |
Kind regards |
