Parameterization Default settings Configurable characteristics I/O Modules with Intrinsically-Safe Signals C79000-G7076-C152-04 SIMATIC S7 Ex Digital Modules The parameters for the digital input modules SM 321; DI 4 x NAMUR are set with STEP 7 . You must implement the settings in CPU STOP mode. The parameters set in this way are stored in the CPU during transfer from PG to S7-300. These parameters are transferred to the digital module during the status change from STOP RUN. Alternatively, you can also change several parameters in the user program with the SFCs 55 to 57 (refer to /235/) . The parameters for the 2 parameterization alternatives are subdivided into: Static parameters Dynamic parameters Table 2-1 below shows the characteristics of static and dynamic parameters. Table 2-1 Static and dynamic parameters of SM 321; DI 4 x NAMUR Parameter Set with CPU status Static PG STOP Dynamic PG STOP Dynamic SFCs 55 to 57 in user program RUN The SM 321; DI 4 x NAMUR features default settings for diagnostics, interrupts etc. (see Table 2-2). These default settings are applicable when the digital input module has not been parameterized via STEP 7 . The characteristics of the SM 321; DI 4 x NAMUR can be parameterized with the following parameter blocks: Basic settings Diagnostics Hardware interrupts 2-7
