Safety
Intended use
The product serves as a protocol converter between Modbus/TCP and CANopen. It can be
used with various Pilz products as well as third-party products, provided they support the
documented properties and requirements.
} Modbus/TCP
The Gateway can be used with products that operate as connection Client during data
exchange. The product must support at least one of the documented function codes .
} CANopen
The Gateway can be used as a passive subscriber (Slave) in a CANopen network. The
basic functions of communication via CANopen correspond to the System Description
published by the CANopen User Group.
The Gateway may not be used for safety-related functions.
Intended use includes making the electrical installation EMC-compliant. The product is de-
signed for use in an industrial environment. It is not suitable for use in a domestic environ-
ment, as this can lead to interference.
The following is deemed improper use in particular:
} Any component, technical or electrical modification to the product
} Use of the product outside the areas described in this manual
} Use of the product outside the technical details (see chapter entitled “Technical De-
tails”)
Electromagnetic compatibility
To ensure electromagnetic compatibility the correct procedures must be carried out during
installation.
A device is electromagnetically compatible if:
} It functions without error in a given electromagnetic environment
} It does not adversely affect its own environment.
Electromagnetic interference can reach the devices through:
} Fields
} Power supplies
} Earth cabling
} Bus connections
} Interfaces
} Input and output cables
The interference can be transferred from the producer (source) to the receiver (interference
sink) via the coupling routes.
Interference reaches the interference sink (e.g. the control system devices) in various ways:
} DC coupling:
DC coupling occurs if the source and sink of interference have common cable connec-
tions. The common cable presents complex resistances, inducing potential differences.
