Abstract

Apparatus and associated methods relate to a safety control system having a processor that (1) automatically interrogates a portable data storage device, (2) determines whether a configuration profile of the safety control system matches a stored configuration profile in the portable data storage device, (3) obtains network settings of the safety control system, and (4) stores network settings into the portable data storage device. In an illustrative example, a safety control system may include a processor designed to perform operations to configure the safety control system with a configuration profile stored in the portable data storage device or download network settings of the safety control system to the portable data storage device under some predetermined conditions. By using the above method, the safety control system may be quickly configured, and network settings may be easily obtained and backed up.

First claim

What is claimed is:

1. A computer program product (CPP) comprising a program of instructions tangibly embodied on a computer readable medium wherein, when the instructions are executed on a processor, the processor causes operations to be performed to automatically handle network settings, the operations comprising:
establishing, by a first program of executable instructions residing on a data storage device operably connected to at least one processor that automatically executes the first program of executable instructions upon connection of a portable data storage device to a safety control system comprising the at least one processor, a data transfer link to receive data from the portable data storage device that stores a first configuration profile for the safety control system;
determining whether the safety control system is in a predetermined state; and,
if the safety control system is not in the predetermined state, then:
(a) accessing, by the at least one processor, the portable data storage device;
(b) determining, by the at least one processor, whether the first configuration profile matches a second configuration profile pre-existing in the safety control system;
(c) if the first configuration profile matches the second configuration profile, then transferring, by the at least one processor, a copy of a content of a second network settings of the safety control system to the portable data storage device via the data transfer link; and,
(d) if the first configuration profile does not match the second configuration profile, then configuring, by the at least one processor, the safety control system to enter a lockout state.

2. The CPP of claim 1 , further comprising:
if the safety control system is in the predetermined state, then:
accessing the portable data storage device; and,
automatically transferring a copy of a content of the first configuration profile and a first network settings to the safety control system.

3. The CPP of claim 2 , further comprising: executing the first configuration profile on the safety control system in response to a power cycle.

4. The CPP of claim 1 , further comprising: upon termination of the data transfer link and cycling power to the safety control system, resuming the safety control system in normal operation using the second configuration profile.

5. The CPP of claim 1 , wherein the predetermined state comprises a predetermined factory default state.

6. A safety control system comprising:
at least one monitored input port;
at least one safety output port;
a processor operatively coupled to the at least one monitored input port and the at least one safety output port;
a data transfer link interface operatively coupled to the processor; and,
a data store coupled to the processor and containing a program of instructions that are automatically executed by the processor in response to connection of a portable data storage device to the processor by the data transfer link interface,
wherein the program of instructions, when executed by the processor, cause the processor to perform operations to automatically download network settings to the portable data storage device, the operations comprising:
in response to the connection of the portable data storage device, receiving data from the portable data storage device corresponding to a first configuration profile for the safety control system, the first configuration profile being stored on the portable data storage device;
in response to receiving the data, determining whether the safety control system is in a first predetermined state;
in response to determining that the safety control system is not in the first predetermined state, then:
determining whether the first configuration profile stored on the portable data storage device matches a second configuration profile pre-existing in the safety control system; and,
in response to determining that the first configuration profile matches the second configuration profile, then reconfiguring the portable data storage device as a safety configuration device based on the configuration of the safety control system, the reconfiguration comprising transferring a copy of contents of a second network settings of the safety control system to the portable data storage device via the data transfer link.

7. The safety control system of claim 6 , wherein the first predetermined state comprises a predetermined factory default state.

8. The safety control system of claim 6 , further comprising a user interface configured to indicate whether the safety control system is in the first predetermined state.

9. The safety control system of claim 6 , further comprising a user interface configured to indicate whether the first configuration profile matches the second configuration profile.

10. The safety control system of claim 6 , wherein the safety control system comprises a first safety relay, a second safety relay, and a safety controller.

11. The safety control system of claim 6 , wherein the first and the second configuration profile comprises logic control functions that, when executed by the processor on the safety control system, cause the safety control system to perform operations to control safety output signals in response to monitored input signals.

12. The safety control system of claim 6 , wherein the operations further comprises: if the safety control system is in the predetermined state, then:
accessing the portable data storage device; and,
automatically transferring a copy of contents of the first configuration profile and a first network settings to the safety control system.

13. The safety control system of claim 12 , wherein the operations further comprise: executing the first configuration profile on the safety control system in response to a power cycle.

14. The safety control system of claim 6 , wherein the operations further comprise: if the first configuration profile does not match the second configuration profile, then configuring, by the processor, the safety control system to enter a lockout state.

15. The safety control system of claim 6 , wherein the operations further comprises: upon termination of the data transfer link and cycling power to the safety control system, resuming the safety control system in normal operation using the second configuration profile.

16. A safety control system comprises:
at least one monitored input port;
at least one safety output port;
at least one processor operatively coupled to the at least one monitored input port and the at least one safety output port;
a data transfer link interface operatively coupled to the at least one processor; and,
a data store coupled to the at least one processor and containing a program of instructions that, when executed by the at least one processor, cause the at least one processor to perform operations to automatically download network settings to a portable data storage device in response to connection of the portable data storage device to the at least one processor by the data transfer link interface, the operations comprising:
receiving data from the portable data storage device that stores a first configuration profile for the safety control system;
determining whether the safety control system is in a predetermined state; and, if the safety control system is not in the predetermined state, then:
(a) accessing, by the at least one processor, the portable data storage device;
(b) determining, by the at least one processor, whether the first configuration profile matches a second configuration profile pre-existing in the safety control syst
