Definitions
- the invention relates to a method for diagnosing field devices of process automation technology according to the preamble of claim 1.
- Field devices for flow, level, pressure, temperature determination etc. are generally known. They are used to record the corresponding process variables mass, volume, flow, level, pressure, temperature, etc.
- These field devices each provide measured values that are a measure of the process variable recorded.
- the measured values are forwarded to a control unit (programmable logic controller PLC, control room or control system).
- PLC programmable logic controller
- control room or control system As a rule, the process is controlled from the control unit, where the measured values of the different field devices are evaluated and control signals for actuators are generated based on the evaluation, which thereby influence the process flow (e.g. via valves).
- the signal transmission between the field devices and the control unit takes place according to the well-known standards for data transmission (HART®, Profibus®, Foundation Fieldbus® or CAN Bus® etc.).
- intelligent field devices In addition to the pure measured values, intelligent field devices also provide diagnostic information and maintenance information.
- Program code is stored and this after a request by the Control system is running. This program code is only suitable for this or identical field devices.
- the program code To change the diagnostic functions, the program code must be rewritten and then transferred to the memory of the relevant field device at great expense.
- the program code stored in the field device is therefore static and works according to special, defined rules.
- the object of the invention is to provide a method for diagnosing field devices of process automation technology, which is not only suitable for a specific type of field device and which is very flexible, inexpensive and easy to carry out.
- the essential idea of the invention is to use a software agent for diagnosing field devices of process automation technology, which is suitable for different field devices and independently monitors the corresponding field device in order, for. B. Find malfunctions.
- FIG. 1 shows a schematic representation of a network of process automation technology
- Fig. 2 shows a schematic representation of the hardware of a field device.
- 1 shows a network of process automation technology in more detail.
- Several workstations workstations WS1, WS2) and several gateways G1, G2 are connected to a data bus D1.
- the gateway G1 is connected to a fieldbus segment SM1.
- the fieldbus segment SM1 essentially consists of several field devices F1, F2, F3, F4, F5.
- the gateway G2 is connected to a fieldbus segment SM2, which essentially consists of the field devices F5, F6, F7 and F8.
- the gateway also has several I / O modules.
- the field devices F can be configured and parameterized from the workstations WS1, WS2. Appropriate operating tools are installed on the workstations WS1 and WS2.
- the data bus D1 in the control level E1 works according to the Ethernet standard (eg high-speed ethemet standard HSE).
- the fieldbuses at the field level (fieldbus segments SM1,
- a sensor transducer S is connected to a microprocessor MP via an analog-digital converter AD.
- the microprocessor MP is connected to the fieldbus FB via a fieldbus interface FS.
- the microprocessor MP is connected to two memories, a RAM and an EEPROM memory and a display control unit AB.
- Control programs that determine the functionality of the field device are stored in the EEPROM memory of the field device.
- Control programs is a software agent.
- Software agents are well known, they work autonomously, i.e. they act independently within certain limits, they work proactively and actively pursue one or more goals.
- the software agent monitors different data in the field device and automatically searches for malfunctions. If it detects a malfunction, it reports this to the control system.
- the software agent is also able to remedy malfunctions in the field device independently.
- field devices from different manufacturers can be used on a specific fieldbus. Certain functions and associated parameters are combined in a function block. Examples of function blocks are analog input, digital output, PID controller etc.
- the software agent independently creates links to the function blocks in the field device or accesses the links between the function blocks.
- the software agent can restore broken connections (links) that are necessary between the function blocks for data exchange, e.g. B. if a field device has been replaced by another.
- a major advantage of such a software agent is that it can be used for different field devices.
- the software agent can also monitor and analyze correlated data from different field devices and generate a corresponding avoidance in the event of an error.
- the software agent recognizes e.g. B. whether a field device needs to be recalibrated in the near future because certain deviations from setpoints have occurred.
- the software agent can also analyze the traffic on the data bus and, if necessary, identify malfunctions.
- the software agent is not only suitable for performing diagnostic functions, but is also suitable for predictive maintenance.
- the software agent can also serve as a filter for information and thus perform asset management functions.
- a large amount of information is generated in the field device, e.g. Manufacturing settings, calibration and maintenance data, day and serial no. Device and version identification, location, application and process data, manufacturer, customer and factory profile, order code, last maintenance, material information, performance index etc.
- the software agent collects this information and stores it in the field device or in another Component of the network. This information is therefore available regardless of the system. No specific tools are required to query them.
- the software agent can also carry out configuration or parameterization tasks.
- the essential idea of the invention is to install a software agent in a field device or in another unit connected to the data bus, which software agent independently performs various functions.
