It enables the simultaneous operation of a number of nodes (programming devices, text display operator interfaces, and operator panels) from one or more CPUs.
Glossary Glossary-10 Automation System S7-400 Hardware and Installation A5E00850741-01 O OB → Organization Block OB Priority The operating system of the S7-400 CPU dif ferentiates between various priority classes, for example, cyclic program processing, process interrupt-controlled program processing.
Glossary Glossary-1 1 Automation System S7-400 Hardware and Installation A5E00850741-01 Parameters, Static In contrast to dynamic parameters, static parameters of modules cannot be changed by means of the user program, but only via STEP 7 (not in the RUN state); for example, input delay of a digital signal input module.
Glossary Glossary-12 Automation System S7-400 Hardware and Installation A5E00850741-01 R RAM The RAM (Random Access Memory) is a semiconductor memory with random access (read/write memory). May be used as for storing interim data for later use. This memory is not retentive, that is, its data are lost after power failure.
Glossary Glossary-13 Automation System S7-400 Hardware and Installation A5E00850741-01 Segment → Bus segment SFB → System Function Block SFC → System Function Signal Module Signal modules (SMs) are the interface between the process and the programmable controller .
Glossary Glossary-14 Automation System S7-400 Hardware and Installation A5E00850741-01 System Diagnostics System diagnostics is the detection, eval uation, and reporting of errors occurring within the programmable controller . Examples of such errors are: program errors or failures on modules.
Glossary Glossary-15 Automation System S7-400 Hardware and Installation A5E00850741-01 Tim e r (T ) T imers are an area in the system memory of the CPU. The contents of these t imers are updated by the operating system asynchronously to the user program.
Glossary Glossary-16 Automation System S7-400 Hardware and Installation A5E00850741-01 V V aristor V oltage-dependent resistor W W arm Restart During a CPU startup and before cyclic program processing starts (OB1), either OB101 (hot restart), or OB100 (restart / warm start), or OB102 is processed first.
