Abstract

Apparatus and associated methods relate to a remote safety input/output device configured to deliver both safety signals and sensor level diagnostics signals in an industrial safety communication network. In an illustrative example, a safety communication device (SCD) may include a safety port operably coupled to serially connected safety devices. The (SCD) may include pre-loaded safety signal profiles (SSPs) and an input system detection engine (ISDE). The ISDE may, for example, automatically identify a device type and a topological configuration of the serially connected safety devices based on a signal received at the safety port and the pre-loaded SSP. For example, when a safety device signal is received at the safety port, the ISDE may automatically identify whether the signal is a safety signal or a diagnostic signal. Various embodiments may advantageously provide plug-and-play installation of the safety devices to the industrial safety communication network.

Dependent claims

A safety communication system comprising:

a safety controller (110) comprising a remote mapping data structure (330);
and,
a safety communication device (100) comprising:
a control port (155) operably coupled to the safety controller via a safety communication network (115);
a safety port (150) configured to couple to at least one safety device, wherein each of the at least one safety device is serially connected to the safety port;
pre-loaded safety signal profiles (SSPs) (180), wherein the SSPs are predetermined and static in operation, and comprise a device identification mapping (230) and a signal conversion mapping (235);
a communication engine (175) comprising a program of instructions configured to
generate a control signal at the control port,
an input system detection engine (ISDE) (170) comprises a program of instructions configured to automatically identify a device type based on a signal received at the safety port, and a configuration of the at least one safety device serially connected to the safety port, wherein the device type comprises a safety device and a diagnostic device;
and,
a processor (165) coupled to the control port, the safety port, the SSPs, the communication engine, and the ISDE such that, when a safety device signal is received from a signal origin device at the safety port, the processor executes the ISDE to automatically identify a device type of the signal origin device based on the device identification mapping, and, based on the device type and the safety device signal, the processor executes the communication engine to generate at least one of a safety signal and/or a diagnostic signal to the safety controller over the safety communication network based on the signal conversion mapping, such that the at least one of a safety signal and/or a diagnostic signal is processed based on the remote mapping data structure.
