Figure 2 is a schematic illustration of the interface of the field device 10 in accordance with a variant embodiment of the present invention. The interface of the field device 10 includes a microprocessor 38 that is connected to the module 20 of the connector that connects to the computer 14 (shown in Fig.1). It is preferable that the interface of the field device 10 includes an analog-to-digital Converter 36 connected to the microprocessor 38. The Converter 36 is connected to the measuring circuit 32 through the logic circuit 34 controls. The microprocessor 38 is also connected to the external bus 40 data, through which it interacts with the permanent storage device 42 and a memory 44 with a random sample. Via the bus 40 data, the microprocessor 38 may also interact with the module 26 of the Protocol interface and the second interface module 28 of the Protocol (not mandatory) for transmitting signals on respective communication paths of the process. In variants of the embodiment, which is consist of several modules interface Protocol, each module is designed in such a way that it conveyed the message in accordance with a communication Protocol of a certain standard process. For example, the module 26 of the Protocol interface may be configured to transmit messages in accordance with the HART®Protocol, while an optional second module 28 Protocol interface may be configured to transmit messages in accordance with the Protocol FOUNDATION™ Fieldbus. Additionally, while Figure 2 illustrates a couple of modules, options embodiments of the present invention can be implemented using any suitable number of such modules, including one. Additionally, while both modules 26, 28 of the interface connected to the terminals 50, 52, modules, interface Protocol wireless communication cannot be connected to terminals 50, 52, and instead they must be connected to a suitable antenna. In accordance with a variant embodiment of the present invention, the microprocessor 38 via hardware, software or combinations thereof configured to apply a measuring circuit 32 and/or analog-to-digital Converter 36 to diagnose the voltage at the terminals 50, 52, to determine whether supplied attached to the communication path process electricity and/or can you provide SignalUp the path. The interface module 10 includes a module 30 meals, possessing a functioning relationship with all components of the interface module 10, as illustrated in figure 2. In variants of the embodiment where the interface module 10 is connected to the computer 14 via a wired connection (such as a USB connection), the module 30 power supply configured to perform mode and/or convert energy received from the computer 14 to suitable levels for the circuit module 10 of the interface.

For example, in variants of the embodiment in which the used network system HART®is preferred that the module 30 power supply includes a resistor of 250 Ohms. However, for the other networks and communication protocols may be required and other schemas. Many "smart" devices (field devices) are two-wire devices, where the power supply device, and implementation of digital communication occurs on the same two wires. These devices are either insensitive to polarity, or have the wrong polarity protection. Variants of the embodiment of the present invention typically allow technicians to perform their tasks on the device is supplied with power in the work area or lab technician. The interface of the field device 10 may simply provide a link (for example, with a device supplied with power in the work area) or may actually provide electricity and at the same time to ensure the transmission of signals (for example, when the initial launch of the device on the stand). One important factor in the design of the interface of the field device is that it can provide communication and power field devices, but it also prevents the technician to serve the electricity is already supplied with power plant of the field device and/or automatically determine the polarity of the field device. In accordance with a variant embodiment of the present invention, the interface 10 of the field device includes a built-in power module 30, which allows t is nicheskomu specialist to supply electric power and communication signals to the field devices not having a separate power source and is not connecting to it. However, the application of additional power to the field device, which is already supplied with electricity via the active path control may hinder a field device output signals and information to the control system, potentially causing serious consequences. Therefore, it is preferable that the variants of embodiment of the present invention also include methods of safely detect power and/or supply power to the field device. In particular, it is preferred to use variants of the embodiment disclosed herein, it was possible to detect the electric power and to prevent the power supply, if the connected device is supplied with electricity. When the interface of the field device supplies power to the field device, and the conclusions intentionally or even unintentionally disconnected from the field device, the energy supply coming from the module interface of the field device is disabled. The polarity of the field device can also be determined using the measuring circuit 32 so that the technician did not have to deal with the correct polarity. As mentioned above, the module interface of the field device can be used for AB is matichenkov discovery of electricity at the field device and, it is possible to power the field device. In some embodiments, embodiments of the module 10 interface of the field device is intrinsically safe. Compliance with the requirements of intrinsic safety means conformity to the Technical specifications intrinsic safety, for example one or more sections of the standard, published Merzavtsem agreement (Factory Mutual Research) in October 1998, referred to as the APPROVED STANDARD INTRINSICALLY safe apparatus AND ASSOCIATED DEVICES INTENDED FOR USE IN CLASS I, II and III. SECTION 1 HAZARDOUS (CLASSIFIED) LOCATIONS, CLASS NUMBER 3610. Figure 3 is a block diagram of the method of connection of General-purpose computer with the field device using the module interface of the field device in accordance with a variant embodiment of the present invention. The method 100 begins to operate at the block 102, where the technician sends the request to the interface module field device (modem) power supply attached field device. Upon the initial connection of the interface module field device to field device occurs, the operation defaults, consisting in the fact that the module interface of the field device fails to submit the attached field device no electricity. The module interface of the field device has the ability to request and what the motivation for the built-in source 30 power supply to supply power to the attached field device. This may be a request to the software or, for example, to a physical push button or switch. In block 102, the technical specialist is actually requesting the information that the electric power is applied to terminals 50, 52 by means of software or a physical switch. Control then proceeds to block 104, where the interface module field device, such as module 10, measures the DC voltage at terminals 50, 52 preferably using a measuring circuit 32. If the measured voltage is above a minimum level for the network supplied by the power supply, the power supply is not available. The module interface of the field device then informs the technician information that is attached field device is supplied with power and that no power no longer is it necessary to submit, as indicated at block 106. However, if the measured DC voltage is below the minimum level for the field device is supplied with power, control passes to block 108, where the terminals 50, 52 is energized, the limited current. Limit the current and voltage set for the corresponding type of network. The current movement are constantly checked and it is expected that the field device within a predetermined expected time run away with ourselves min the minimum amount of current. Therefore, the continuation of the execution of the method 100 is expected to block 110, before the expiration of the maximum run time of the field device, and then process control passes to block 112. At block 112, the method 100 determines whether itself is attached field device current is greater than the minimum level. If the field device assumes the current is above the minimum level, then control passes to block 114 through line 116, where the current field device is continuously monitored to determine whether it is the specified minimum. When attached field device assumes the current is above the minimum level, the block 114 essentially forms a loop, thereby continuously controlling the admission of current to the field instrument. When the field device stops receiving the output current level is above the minimum level, control passes to block 118, where a limited current voltage is switched off and the technician receives information indicating that the power supply is disabled. Let's return to block 112, if the instrument does not assume the current is above the minimum, then control passes to block 120, where switches the polarity of the limited current voltage. Control then proceeds to block 122, where the expected continuation of the execution of the method, after a maximum run time of the field device, and then control the PE ahadith to block 114. Figa is a schematic illustration of the module interface of the field device with internal power supply and protection/polarity associated with two-wire field device, in accordance with a variant embodiment of the present invention. Module 10 detects the DC voltage is less than the threshold value, on the terminals of the field device, and then supplies the electric power and supplying signals to/from field device (assuming that the technician has requested the supply of electric power to the field device). This situation typically occurs when the original starting field of the device or during operation technician at the laboratory bench. FIGU is a schematic illustration of the module interface of the field device with internal power supply and protection/polarity associated with the communication path process located between the control system indicator circuit or other power supply source and a two-wire device. As illustrated in Figv, module 10-interface field device detects the violation of the DC voltage relative to the minimum threshold on the communication path process and only provides signals to/from the device, etc is needed. The situation is illustrated in Figv can typically occur when the module interface of the field device communicates with a field device that is connected to the operational control system or display system process. Although the present invention has been described with reference to preferred variants of the embodiment, specialists in the art it should be clear that in such form and detail may be made without departure from the essence and scope of the invention. For example, despite the fact that variants of the embodiments described herein are presented in relation to the modem HART®, variants of the embodiment of the present invention can be implemented with any suitable two-wire industrial Protocol, where the supply of electricity and the transmission of signals occur on the same two wires. Additionally, variants of the embodiment of the present invention can be implemented using multiple protocols in a single modem, in the presence or absence of automatic detection of the communication Protocol. 1.
