Problems solved by technology

Unfortunately, this can result in a complete loss of observation or control of its associated field devices
Among other problems, non-redundant process controllers that include a single microprocessor I / O module cannot perform fail-safe actions during a boot failure of the I / O module's microprocessor, which may occur after a firmware upgrade of the microprocessor Occurs when unable to boot
Therefore, during a firmware upgrade of a process controller's I / O modules, it is often necessary to shut down part or all of the industrial process, resulting in lost production and associated monetary loss
While it is possible to incorporate multiple redundant process controllers or I / O modules in a control and automation system, this adds complexity and cost to the overall system, and it is not always possible to have redundant process controllers or I / O modules in a system. I / O module

Embodiment Construction

[0015] Discussed below Figure 1 to Figure 5 , And various examples used to describe the principle of the present invention in this patent document are made by way of illustration only, and should not be construed as limiting the scope of the present invention. Those skilled in the art will understand that the principles of the present invention can be implemented in any suitable manner and in any type of suitably arranged device or system.

[0016] figure 1 An exemplary industrial process control and automation system 100 according to the present disclosure is shown. Such as figure 1 As shown, the system 100 includes various components that facilitate the production or processing of at least one product or other material. For example, the system 100 is used here to facilitate the control of components in one or more plants 101a-101n. Each plant 101a-101n represents one or more processing facilities (or one or more parts thereof), such as one or more manufacturing facilities fo...

Abstract

A method is disclosed and includes receiving, at a first processing device (206) of an input / output module (IOM) (154), new firmware data (408, 508) for the IOM. The method also includes sending an output hold command (418, 518) from the first processing device to a second processing device (212) of the IOM. The method further includes upgrading (422, 522) firmware of the IOM with the new firmwaredata using the first processing device and attempting (422, 522) a reboot of the first processing device. In addition, the method includes, in response to the output hold command and during the upgrading of the firmware and the rebooting of the first processing device, using (424, 524) the second processing device to cause a field circuit (202) of the IOM to hold at least one previous output signal for one or more external devices (102a, 102b).

Description

Technical field [0001] The present disclosure relates generally to industrial process control and automation systems. More specifically, the present disclosure relates to in-process migration of non-redundant input / output (I / O) firmware. Background technique [0002] Industrial process control and automation systems are often used to automate large and complex industrial processes. These types of control and automation systems routinely include process controllers and field devices such as sensors and actuators. Process controllers typically receive measurements from sensors and generate control signals for the actuators. In many systems, the process controller includes or is used with one or more input / output (I / O) modules, each of which can be used to provide signals to one or more field devices and from one or more field devices. The device receives the signal. [0003] A popular hardware architecture for I / O modules uses a single microprocessor. During the firmware upgrade...
