Una planta de energía en el noreste estaba bajo presión para cumplir con los requisitos de la EPA de la presentación de informes de consumo de combustible (utilizado para el monitoreo de las emisiones). El problema era excavar una zanja costosa de la casa de la bomba al edificio de la sala de control con el fin de administrar el cable de fibra óptica que emitía una señal del medidor de flujo para el historial de la planta en donde se podrían generar informes. El costo hubiera sido de $20,000.00 por la sola excavación de la zanja.
La Planta contiene numerosos lugares de desagüe de los medidores. Estas ubicaciones remotas deben ser monitoreados y las señales de flujo introducidas en el sistema DCS. Hay alimentación AC disponible en cada sitio, pero actualmente no hay manera de traer señales analógicas a lo largo de la infraestructura existente. Cada lugar tendrá instalado un medidor de flujo magnético Yokogawa AXF. Los (4) sitios actuales que figuran a continuación tendrán que ser conectados a la Planta Química Suwanee River. No habrá más sitios adicionales en el futuro.
The site consists of (10) remote wells with one central location that will collect all the data and have it available via Modbus TCP into the plant's DCS. Each well site has (1) 4-20 madc input from a flow meter, along with (1) DO signal to start the pump and (1) DI to read back the pump status. There is AC power available at each site. A path study was done before based on the GPS coordinates given for each site.
Here's how Shell upgraded from a pneumatic instrumented plant to a fully digital control system.
Decades of operation, modernization and expansion have left many chemical plants with a somewhat haphazard automation mix of different controls, process control systems, remote I/Os and field devices. The various components may use different communication protocols such as HART, PROFIBUS or FOUNDATION Fieldbus, and are often based on different device integration technologies.
This error message is generated when you try to download a configuration to the YFGW410 when the OTA (over-the-air) provisioning mode is enabled. To allow a download to proceed, you must disable the OTA provisioning mode.
Here is the error that you will see in the configurator when download is attempted with OTA provisioning active.
Here is the screen in the monitor webserver (found under tools menu), where you enable/disable the OTA provisioning. Click into the box labeled "Enable Provisioning Network" to change status.
The CF file is the Capabilities File and is used during configuration of the ISA100 system. It includes information such as the device vendor name, model code, revision, list of process values and number of data parameters. Each CF file must be uploaded into the YFGW410 gateway one time during the configuration process for each type of transmitter being configured. A different CF file version is required for each distinct version number of a given transmitter.
The DD file is a Device Description file and is used with tools such Yokogawa's device configuration tool, Fieldmate. DD files show information of parametres such as the data structure and attributes.
The file name extension for each file is as follows:
******.cff = Capabilities File
******.ff5 = Device Description File (1/2)
******.sy5 = Device Description File (2/2)
Export for Modbus Client is used to generate a CSV that can be imported by Centum-VP.
Export for Modbus mapping is used to generate a CSV that can be imported by OPC servers, Yokogawa GA10 software and other PC software programs.
Fieldmate Lite is the free version of Yokogawa's device configuration and management tool.
Fieldmate Lite has the same functions as the full release (purchased) version of Fieldmate with the exception that Fieldmate Lite is limited to a total of (7) devices in the offline device database.
The download link for Fieldmate Lite is in the upper right corner of this article.
It is the same battery. TL-5930/S of TADIRAN is used. The battery case used by the FN310 and FN510 is different from the YTA510, EJX series and YTMX580.
The YCA part number for two batteries only (no case), is F9915NR.
The YCA part number for battery pack with two batteries for YTA510, EJX-B series, and YTMX580, is F9915NQ.
The YCA part number for the YTA510, EJX-B series, and YTMX580 battery case only (no batteries), is F9915NK.
The YCA part number for the FN310 and FN510 battery case only is F9090GD.
It is setting value for retry repetition during communications between a transmitter and a router or access point. In the "X2" mode twice the bandwidth is used for retry compared to "Normal" mode.
It reduces latency for retry but increases use of wireless resources.
The LCD display of a R1 (fixed antenna) transmitter is continuously enabled under any one of the following conditions:
Changing items 1 or 2 or eliminating the error condition in item 3 will allow the transmitter to go back to disabled LCD display mode.
The "Modbus Setting" menu in the YFGW410 has three tabs, "Modbus Settings", "Input Registers", and "Holding Registers".
The holding register area (registers 4xxxx) is used only for devices with output values such as the FN510 which as a digital output function. Devices such as YTA510 temperature transmitter, EJXB series pressure transmitters, FN310 protocol converter and YTMX580 multi input temperature transmitter do not have any outputs and do not use the holding registers.
The first screenshot below shows the "Holding Register" tab in the YFGW410 web configurator. The devices listed do not have outputs so there are no available parameters shown.
The second screenshot shows the "Input Register" tab (3xxxx registers) parameter assigment areas with the AI for and EJX populated in 30522/30533.
No. The DO function of the FN510 cannot be used with the YFGW710 or GX20W as they do not support the holding register which is required for DO function. The YFGW410/YFGW510 combination must be used to support the FN510 DO function.
Communication between the YFGW410 gateway and the YFGW510 access point has strict limitations for delays in order to implement precise time synchronization. For this reason, the YFGW610 media converter is required when using the YFGW510 with fiber optic communication option. Using a non-Yokogawa media converter will not allow performance to be guaranteed.
No limitations exists.
FN310 can be used in R2 (YFGW410/510) system and R1 (YFGW710 or GX20W) system.
The four standard parameters (PV, SV, TV, QV) in the wired HART transmitter are transferred to ISA100 wireless by the FN310-J adapter.
The FN310-J must be configured so it is matched to the host HART device.
The changes in social environment, such as globalization of enterprise activities, depletion of natural resources, and eco-oriented movement will affect the structure of mass production. Control systems must be prepared with flexibility and scalability in both size and function to adjust to the changes.
To configure a compact, low-power medium attachment unit for field buses, i.e., a fieldbus MAU, an IC comprising a power generator, transmitter/receiver and other functions is needed. While we at Yokogawa had already developed a fieldbus MAU IC, we have now developed another MAU IC that includes large-scale design changes made mainly to comply with the low-power signaling requirements of the fieldbus specifications.
Progress in digital signal processing and network technologies has enabled advanced functions which cannot be achieved by traditional field devices with 4-20 mA signal, to be implemented on field devices. Standardization of international fieldbus specifications, notably the FOUNDATION™ Fieldbus, has enabled users to build optimum field networks comprised of freely chosen field devices from various device vendors.
