This standard concerns itself withGeneral Safety Requirements of a wide range of Information Technology Equipment. Its intention is to helpreduce the risks of fire, shock or injury to persons coming into contactwith IT equipment and to enable manufacture
Information technology equipment - Safety - General requirements
This standard is applicable to mains-powered or battery-powered information technology equipment, including electrical business equipment and associated equipment, with a RATED VOLTAGE not exceeding 600 V. This standard is also applicable to such information technology equipment: ? designed for use as telecommunication terminal equipment and TELECOMMUNICATION NETWORK infrastructure equipment, regardless of the source of power; ? designed and intended to be connected directly to, or used as infrastructure equipment in, a CABLE DISTRIBUTION SYSTEM, regardless of the source of power; ? designed to use the AC MAINS SUPPLY as a communication transmission medium (see Clause 6, Note 4 and 7.1, Note 4). This standard is also applicable to components and subassemblies intended for incorporation in information technology equipment. It is not expected that such components and subassemblies comply with every aspect of the standard, provided that the complete information technology equipment, incorporating such components and subassemblies, does comply. NOTE 1 Examples of aspects with which uninstalled components and subassemblies may not comply include the marking of the power rating and access to hazardous parts. NOTE 2 This standard may be applied to the electronic parts of equipment even if that equipment does not wholly fall within its Scope, such as large-scale air conditioning systems, fire detection systems and fire extinguishing systems. Different requirements may be necessary for some applications. This standard specifies requirements intended to reduce risks of fire, electric shock or injury for the OPERATOR and layman who may come into contact with the equipment and, where specifically stated, for a SERVICE PERSON. This standard is intended to reduce such risks with respect to installed equipment, whether it consists of a system of interconnected units or independent units, subject to installing, operating and maintaining the equipment in the manner prescribed by the manufacturer.

This list is not intended to be comprehensive, and equipment that is not listed is not necessarily excluded from the Scope. Equipment complying with the relevant requirements in this standard is considered suitable for use with process control equipment, automatic test equipment and similar systems requiring information processing facilities. However, this standard does not include requirements for performance or functional characteristics of equipment.

This part of IEC 62435 provides information for integrating the HART1 protocol into the FDT interface specification (IEC 62453-1). This PAS neither contains the FDT specification nor modifies it.
Field device tool (FDT) interface specification - Part 4: HART communication
This part of IEC 62435 provides information for integrating the PROFIBUS protocol into the FDT interface specification (IEC 62453-1). This PAS neither contains the FDT specification nor modifies it.
Field device tool (FDT) interface specification - Part 3: PROFIBUS communication
1.1 Performance This part of IEC 62453 includes the engineering and commissioning of field devices. Functionality for documentation and audit trail support is also considered. Examples and use cases are mainly given for actors, sensors and remote I/Os. Of course, FDT is prepared to be used for devices like drives, analyzers, recorders, etc. as well. The FDT interfaces are designed in such a way as to support all significant fieldbus protocols. The main focus of this version of FDT does not lie on any specific fieldbus protocol. Due to the scalable structure of FDT it will be easy to add new schemas in order to extend the scope to new protocols. The FDT concept allows a device manufacturer to provide his device specific functionality within an engineering system. So the main capacity of FDT depends on the functionality of the devices and the according applications. This PAS is intended for developers who want to implement FDT components. The FDT concept does not claim to provide a solution for all engineering tasks and the associated tools. Therefore, the engineering subjects "electrical wiring planning, mechanical planning, etc." or the plant management subjects such as "maintenance, optimization, archiving, etc." do not form part of the current performance range of FDT. Some of these aspects may be included with future versions of FDT. 1.2 Audience This PAS is intended as reference material for developers of FDT compliant Frame Applications and DTMs. It is assumed that the reader is familiar with Microsoft ActiveX1 technology and the needs of the Process Control industry or of the field devices. This PAS is intended to facilitate development of DTMs and Frame Applications in the language of choice that supports Microsoft ActiveX. Therefore, the developer of the respective component is expected to be familiar with the technology required for the specific component. Remember, FDT is a client/server architecture implemented in a first step with Microsoft COM.2
