1) I&M data: Set-up and data access in accordance with the provisions in the PROFIBUS Guideline – Order No. 3.502, Version 1.1 of May 2003 2) Changes to digital inputs are tagged with a time stamp locally (in the IM 153 of the ET 200M) and transferred to the CPU by means of a process interrupt. If you want to achieve high-precision time stamping of 1ms with the IM153-2BAx2, a max. of 8 modules per IM can remain plugged in. 3) Normal redundancy according to PNO: "Flying Redundancy" according to standard Slave Redundancy Specification V1.2, Nov. 2004 of PROFIBUS International; Order No 2.212. 4) Changing the configuration in RUN means that changes to the hardware configuration, e.g. reparameterization or the addition of modules, can be performed during normal operation without any adverse effects. How they workThe IM 153 interface module completely handles communication of the modular ET 200M I/O device with the host master device on the PROFIBUS DP. The inputs and outputs are assigned to the respective master during configuration. The IM 153-2 interface module allows the design of redundant PROFIBUS DP systems. On failure of the active branch, the passive IM 153-2 takes over the corresponding functions without interruption. ParameterizationSTEP 7 Configuration is carried out using HW Config by selecting the respective headend from the corresponding HW catalog. The configuration with modules is also carried out from the corresponding HW catalog. Third-party tools Interfacing to third-party masters and configuration using third-party tools is carried out using the GSD file. |
