6 Assigning Parameters to the SM 322; DO x 120/230 VAC/2 A ISOL To find a description of the general procedure for assigning parameters to digital modules, see Section 3.3 of the S and M Programmable Controllers Module Specifications Manual. For details of the parameters of the digital output module, see Appendix A.3 of the S and M Programmable Controllers Module Specifications Manual. Parameters of the SM 322; DO 8 x 120/230 VAC/2 A ISOL Table 1 shows the parameters that you can set and their default setting for the SM 322; DO 8 x 120/230 VAC/2 A ISOL. The default settings apply if you have not performed parameter assignment in STEP 7. Table 1 Parameters of the SM 322; DO 8 x 120/230 VAC/2 A ISOL Parameter Value Range Default Settings Parameter Type Scope Enable Diagnostics interrupts Yes/No No Dynamic Module Behavior on CPU STOP Apply substitute value (EWS) Hold last value (LWH) EWS Dynamic Channel Apply substitute value 1 Yes/No No Dynamic Channel 6

8 Interrupts of the SM 322; DO 8 x 120/230 VAC/2 A ISOL The SM 322; DO 8 x 120/230 VAC/2 A ISOL can trigger diagnostic interrupts. The OBs and SFCs mentioned below are explained in detail in the online help for STEP 7. Enabling Interrupts The interrupts are not present, in other words, they are inhibited without appropriate parameter assignment. Assign parameters to the Interrupt Enable in STEP 7. Diagnostic Interrupt If you have enabled diagnostic interrupts, then active error events (initial occurrence of the error) and departing error events (message after troubleshooting) are reported by means of an interrupt. The CPU interrupts the execution of the user program and processes the diagnostics interrupt block (OB 82). In the user program, you can call SFC 51 or SFC 59 in OB 82 to obtain more detailed diagnostic information from the module. The diagnostic information is consistent until such time as OB 82 is exited. When OB 82 is exited, the diagnostic interrupt is acknowledged on the module. Load Limitations for Horizontal Mounting When mounted with Horizontal Mounting, the module loads need to be restricted such that no two adjacent points may exceed the maximum single-point rating. Load Limitations for Vertical Mounting When mounted with Vertical Mounting, the module loads need to be restricted such that no four adjacent points may exceed the maximum single-point rating. 8
