Page 85 Characteristics The redundant power supply of an S7-400 has the following characteristics: • The power supply module delivers a making current in accordance with NAMUR. • Each of the power supply modules can take over the supply of power to the whole rack if the other one fails.
Page 86: Backup Battery (Option)
Battery Type Only batteries approved by Siemens must be used (see Appendix C: Spare Parts) The batteries can form a passivation layer. Depassivation takes place when the batteries are inserted in the power supply module.
Page 87 Backup Times The maximum backup time is based on the capacity of the backup batteries used and the backup current in the rack. The backup current is the sum of all individual currents of the inserted backed-up modules as well as the requirements of the power supply module when the power is switched off.
Page 88: Controls And Indicators
Power Supply Modules Controls and Indicators Introduction The power supply modules of the S7-400 have essentially the same controls and indicators.The main differences are: • Not all the power supply modules have a voltage selector. • Power supply modules with a backup battery have an LED (BATTF) that indicates an empty, defective, or missing backup battery.

Page 599 Guidelines for Handling Electrostatic Sensitive Devices (ESD) Introduction In this appendix, we explain • what is meant by “electrostatic sensitive devices” • the precautions you must observe when handling and working with electrostatic sensitive devices. Chapter Overview This chapter contains the following sections on electrostatic sensitive devices: Section What is ESD? Electrostatic Charging of Persons...
Page 600 Guidelines for Handling Electrostatic Sensitive Devices (ESD) What is ESD? Definition All electronic modules are equipped with large-scale integrated ICs or components. Due to their design, these electronic elements are very sensitive to overvoltages and thus to any electrostatic discharge. These Electrostatic Sensitive Devices are commonly referred to by the abbreviation ESD.
Page 601 Electrostatic Charging of Persons Charging Every person with a non-conductive connection to the electrical potential of its surroundings can be charged electrostatically. Figure D-1 shows you the maximum values for electrostatic voltages which can build up on a person coming into contact with the materials indicated in the figure. These values are in conformity with the specifications of IEC 61000-4-2.
Page 602 Guidelines for Handling Electrostatic Sensitive Devices (ESD) General Protective Measures Against Electrostatic Discharge Damage Ensure Sufficient Grounding Make sure that the personnel, working surfaces and packaging are sufficiently grounded when handling electrostatic sensitive devices. You thus avoid electrostatic charging. Avoid Direct Contact You should touch electrostatic sensitive devices only if it is unavoidable (for example, during maintenance work).

The following can be reference junctions: resistance thermometer on channel 0 of the module; ³ compensating box, ³...
Page 610 Glossary Declaration Assigning variables (parameters or local data of a block, for example) with a name, data type, comment, etc. Default setting The default setting is a sensible basic setting that is used whenever no other value is used. Destination CPU for interrupt Parameter in STEP 7.
Page 611 Direct communication Direct communication involves assigning local input address areas of an intelligent DP slave (for example, CPU 315-2 with PROFIBUS DP connection) or of a DP master to the input address areas of a PROFIBUS DP partner. The intelligent DP slave or DP master receives the input data that the PROFIBUS DP partner sends to its DP master via these assigned input address areas.
Page 612 Glossary Equipotential bonding An electrical connection (equipotential bonding conductor) that brings the bodies of electrical resources and foreign conductive bodies to an identical or approximately identical potential in order to avoid interfering or hazardous voltages between these bodies. External load memory ³...
Page 613 Function A function (FC) in accordance with IEC 1131-3 is a ³ code block without ³ static data. A function allows parameters to be passed in the user program. Functions are therefore suitable for programming complex functions, such as calculations that are frequently repeated. Functional grounding Grounding which has the sole purpose of safeguarding the intended function of the electrical equipment.
Page 614 Glossary Ground, to To ground means to connect an electrically conductive part via a grounding system to the grounding electrode (one or more conductive parts having a very good contact to ground).

Page 615 Interrupt, diagnostic ³ Diagnostic Interrupt Interrupt, end-of-scan-cycle ³ Hardwareinterrupt Interrupt, hardware ³ Hardware interrupt Interrupt response time The interrupt response time is the time from when an interrupt signal first occurs to calling the first instruction in the interrupt OB. The following general rule applies: Higher priority interrupts take precedence.
Page 616 Glossary Local data Local data are data assigned to a ³ code block that is declared in its ³ declaration section and its variable declaration. It includes (depending on the block): formal parameters, ³ static data, ³ temporary data. Logic block In the context of SIMATIC S7, a logic block is a block that contains part of the STEP 7 user program.
Page 617 Measuring range module Measuring range modules are plugged into the analog input modules for adaptation to different measuring ranges. Memory card Pluggable load memory. Memory cards are credit-card size storage media for CPUs and CPs. They are implemented as ³ RAM or ³ FEPROMs. Memory reset In a memory reset, the following memories of the CPU are deleted: working memory, write/read area of the load memory, system memory.
Page 618 Glossary Non-isolated In the case of non-isolated input/output modules, the reference potentials of the control and load circuit are electrically connected. ³ Organization block Organization block Organization blocks (OBs) form the interface between the operating system of the CPU and the user program. The order in which the user program is processed is defined in the organization blocks.
Page 619 Priority class The operating system of an S7 CPU has a maximum of 28 priority classes (= program execution levels) – for cyclic program scanning or program scanning controlled by hardware interrupt, for example. Each priority class is assigned ³ organization blocks in which the user can program a response.

Page 622 Glossary Restart When a CPU starts up (through the use of the mode selector, for example, or when the power is switched on), either OB 101 (restart), OB 100 (reboot: warm restart) or OB 102 (cold restart) is processed before cyclic program scanning (OB 1).
Page 623 Sequence layer Sequence layers form the interface in M7 between the operating system of the CPU and the user program. The order in which the blocks of the user program are processed is defined in the sequence layers. ³ System function block ³...
Page 624 Glossary STARTUP The STARTUP mode is traversed during the transition from STOP mode to RUN mode. STARTUP can be triggered by the ³ mode selector or following power-on or by means of an operator input on the programming device. Rebooting and restarting are the two different types of startup. Depending on the position of the mode selector, either a reboot or restart is executed in the case of the S7-400.
