SIEMENS SIMADYN D Hardware Usage Guide

SIEMENS SIMADYN D Hardware Usage Guide

The SIMADYN D hardware usage guide covers general technical data, various hardware modules (10 major categories including subracks, CPUs, coupled storage, input/output, communication support, etc.), plug-in cables, operation panel OP2, and other key content. It clarifies the installation specifications (such as EMC, ESD protection), technical parameters (such as voltage range, current capacity), connection configuration, and safety guidelines (including DANGER, Warning, and other level 5 risk warnings) of the hardware, and is suitable for programmers and debugging engineers. It should be used in conjunction with basic knowledge of automation technology.

General Technical Data

(1) Installation and EMC Key Requirements

Grounding and equipotential connection: All components need to be connected through equipotential cables, and cabinets need to be equipped with grounding bars. The cross-sectional area of the grounding cable for sub racks is ≥ 6mm ², and the cross-sectional area of the connecting cable for multiple cabinets is ≥ 16mm ².

Cable requirements: All signal cables must be shielded, and the distance between analog signal cables and power cables must meet the following requirements: when AC<500V>10cm, when AC>1kV>30cm.

Installation gap: When installing the sub rack, the minimum gap should be ≥ 50mm, and the cabinet should ensure air circulation.

Power protection: Line filters need to be installed, and 24V power supplies need to be equipped with noise suppression capacitors.

(2) ESD protection

Definition: Electrostatic discharge (ESD) may damage highly integrated components, and discharge is required before human contact with the components (touching conductive grounded objects).

Operation requirements: ESD wristbands or anti-static shoes should be worn, and the module should be placed on a conductive surface to avoid contact with insulating materials.

(3) Environmental conditions

Scope of project requirements

Working intake temperature: 0 ° C~+55 ° C

Storage temperature -25 ° C~+70 ° C

Operating machinery level 12 (compliant with SN 29050)

Transport machinery level 22 (compliant with SN 29050)
