SIMATIC S7 Ex Analog Modules Influence of value range for output 3-52 Triggering of a diagnostic interrupt is dependent on the parameterization (see Section 3.6.3). Table 3-29 Characteristics of analog modules dependent on position of analog input value in value range Process value in Input value SF LED Diagnostics Interrupt Channel fault LED Rated range Process value – – – – Overrange/ underrange Process value – – – – Overflow 7FFFH lit lit Underflow 8000H lit Entry made 1 ) Diagnostic interrupt 1) Wire break 7FFFH lit lit 1) 1 ) interrupt 1) lit1) Outside parameterized limit 1) depending on parameterization Process value – – Hardware interrupt 1)2) 2) A channel diagnostic error prevents the limit hardware interrupt. Example: An enabled wire break diagnostics renders limits below the wire break threshold ineffective. The characteristics of the output modules depend on what part of the value range the output values are in. Table 3-30 shows this dependency for analog output values.

Influence of faults I/O Modules with Intrinsically-Safe Signals C79000-G7076-C152-04 SIMATIC S7 Ex Analog Modules Faults occurring in analog modules with diagnostic capabilities and corresponding parameterization (see Section 3.6.3 ”Parameters of Analog Modules”) result in diagnositic entry and diagnostic interrupt. Possible faults are listed in Table 3-25 and 3-27 in Section 3.6.4. The SF LED and, if applicable, the channel fault LED light on the analog module. Faults which cannot be parameterized in diagnostics (e.g. fuse blown) result in an entry being made in the diagnostic range and the fault LED lighting irrespective of the CPU operating status. 3-53
