FAQ: Battery Backup for EEPROM - OMRON PLC

QuestionIs a battery for EEPROM memory backup required when using an EEPROM Memory Cassette with C200HS or C200HX/HG/HE Programmable Controllers? Answer  No, the EEPROM Memory Cassette does not require a battery.

QuestionCan a single sensor output be connected to multiple Programmable Controllers Input Units in parallel? Answer  The conditions for setting up this type of connection are as follows: 1.The sum of the total input currents of the Input Units must be below the maximum switching capacity of the transistor in the sensor output. 2.The leakage current from the transistor in sensors output may prevent the inputs to the Input Units from turning OFF. You must be sure that the inputs will turn OFF when sensors output turns OFF.
As a condition for this, the input impedance of the Input Unit and the leakage current can be used to calculate the voltage when the sensor output is OFF. You must be sure t…

What products are recommended as substitutes for the C200H-CPU01 Programmable Controller?

QuestionWhat products are recommended as substitutes for the C200H-CPU01 Programmable Controller? Answer Select any of the following: C200HE-CPU11, C200HE-CPU32, or C200HE-CPU42.
Selection Precautions: 1. A Power Supply Unit must be purchased (e.g., the C200HW-PA204). 2. Check the Memory Unit that was used with the C200H-CPU01. C200HE-CPU11: 3.2 Kwords (built-in RAM) C200HE-CPU32/42: 7.2 Kwords (built-in RAM) Points to Check: C200H-CPU01:

The C200HE/HG/HX cannot be used if the C200H-ID001/002 Input Unit (no-voltage contacts) is used with C200H-CPU01. Check the configuration and use another Unit. (There are …

General Purpose Relays FAQ

QuestionWhat is the approach to perform maintenance for Relays? Answer  There are two main types of maintenance: corrective maintenance (i.e., inspections and replacements that are performed after a failure has occurred) and preventative maintenance (i.e., inspections and maintenance that are performed before a failure occurs). Some of the important issues with preventative maintenance is when to perform inspections and replacements, how to know when that is required, and how to determine the timing. The factors that must be considered when determining maintenance schedules for Relays is the level of importance of the target device, and the required reliability level, when looking at maintenance from the device or system perspective. There are also different types of failure for the different characteristics and items based on the type of Relays. Relays failure types can be broadly classified into failures from wear, typified by worn out contacts, and deterioration failures, such…

Technology Update: SCADA evolves toward MES

Today's SCADA systems are evolving beyond supervisory control and data acquisition with greater functionalities and integration capabilities.
In Food Engineering's 2001 Best Manufacturing Practices Survey (Feb., '01), only five percent of respondents reported having SCADA systems in their plants. We thought that surprisingly low. The problem may lie in the definition. SCADA -- the acronym and abbreviation for Supervisory Control And Data Acquisition -- has become more difficult to define as these systems add more production-management and manufacturing-execution functions, blurring the distinction between SCADA and MES (Manufacturing Execution Systems). The term SCADA emerged during the 1980s from the gas, oil and utilities industries, where it refers to remote monitoring and control of widely distributed plcs and I/O points in facilities such as oil fields, electric-power generating stations, water and wastewater-treatment plants. Eventually the term was applied in manufa…

S7-300 Memory Cards -- Product information -- Technical data

What points do you need to remember during the handling of micro memory cards?

This entry describes how to work with Micro
Memory Cards (MMC). A sample project is also included in Point 4. The
program shows how you can check whether specific data in a data block
is located in the load memory.
1. How should I save blocks or configuration data on the MMC which are transferred online to the CPU?
When you load blocks (OB, FC, FB, DB) and system data (from the
HW Config among other places, for example) into the CPU, they are automatically saved in such a way as to be safeguarded against voltage failure. The MMC is a flash EPROM medium.
2. Is there still need for the "Copy RAM to ROM..." function?
Not for saving blocks. However, if you have changed data blocks,
for instance if you have optimized control parameters, this function
also allows you to save the changed data values on the MMC (i.e. on the
load memory), which means that these new values are also available
following gener…

Transfer of analog values from and to the PROFIBUS DP slave

The analog values are transferred only in part or not at all. How can I clear this problem?ANSWER:
If none or only part of the analog values are transferred, or the transferred values are incorrect, then this might have something to do with the length of the consistent data of the slave (affects S7-300/400 CPUs).
If more than 4 bytes (or exactly 3 bytes) are consistent over the entire length, then you must access the analog values of the slave with the SFCs 14 "DPRD_DAT" and 15 "DPWR_DAT". A description of the SFCs is given in the manual "System Software for S7-300/400 System and Standard Functions". The information on consistent data lengths of the PROFIBUS DP slave are given in the HW Config.
Procedure:In the HW Config you mark the PROFIBUS slave.Double-click the module from which you want to know which consistent areas it has. In the "Address/ID" tab of the "Properties - DP slave" window you can see the length over which th…

S7-400 CPU 41x -- Configuring and programming communication -- Configuring the PROFIBUS interface

What differences are there when configuring S7 connections?

In this description of how to configure S7 connections it is assumed that all the stations are in one S7 project. Types of S7 connections:
With S7 connections you differentiate between bilaterally configured and unilaterally configured S7 connections. Bilaterally configured S7 connections
You recognize bilaterally configured connections by the fact they they receive a connection ID at both endpoints. The partner ID can be identical for both connection partners, but doesn't have to be. The remote endpoint of the S7 connection created is entered automatically in the connection table on the partner side. Unilaterally configured S7 connections
Unilaterally configured S7 connections are configured on the module that actively sets up the S7 connection. If an S7-300 or S7-400 station actively sets up the S7 connection, then you call communication blocks FB/SFB14 "GET" and FB/SFB15 "PUT" in the CPU&…

How can you delete unused tags or objects from a WinCC flexible project?

In order to reduce configuration work, parts of a project are often copied and inserted into a new project.
Here, tags and objects are copied, which are no longer used in the newly created project. WinCC flexible provides a function which can be used to have these unused tags displayed. In the "Edit" menu you select the command "Find in project...". In the window that opens you select the required search options. For example, to find unused tags you select the "Filter" item. In the text list you select "Tag" as the object type.
Under the "In" item you specify the folder in which the search for the object type is to be made. This is particularly useful when there are multiple operator panels in the project. Under "Reference" you select the subitem "Not used by" -> "All types". Then click the "Find now" button. Now on the right you get a display of all the unused tags.
To delete them …

Copying HMI projects integrated in SIMATIC STEP 7 at file level

Can I copy a SIMATIC WinCC flexible project integrated in SIMATIC STEP 7 at file level?  ANSWER:
Copying of HMI projects integrated in STEP 7 at file level (e.g. with Windows Explorer via Copy/Cut and Paste) is not possible in combination with WinCC flexible. 

By copying of HMI projects integrated in STEP 7 (*.hmi) at file level you lose internal references from the WinCC flexible project to the the associated STEP 7 project. Then synchronization between the WinCC flexible project and the STEP 7 project is no longer possible. When you attempt to open an HMI station copied at file level from the SIMATIC Manager, you get a message regarding access to STEP 7 information after opening the HMI station in WinCC flexible ES. Proceed as follows if you want to copy a SIMATIC HMI station from a STEP 7 project:Open the STEP 7 concerned with the SIMATIC Manager.

Start WinCC flexible via "SIMATIC HMI Station > Right-click on WinCC flexible RT > Open object".

How do you archive projects in WinCC flexible and which files are required?

Project archiving and migration
If you wish to archive a WinCC flexible project, you can reduce the volume and file size significantly by archiving just the following project files. Please refer also to the notes at the end of the entry on migrating WinCC flexible projects (opening a WinCC flexible project that is based on a previous version).

No.Project archiving in WinCC flexible 2007 and WinCC flexible 20081Standalone project (a WinCC flexible project not integrated in STEP 7)

Siemens onboard for high-speed trains in China

The Obama administration isn't the only one looking to high-speed rail lines. German train producer Siemens has inked a $1 billion contract to build 100 new high-speed trains for China, the company announced Friday. The company's Velaro train has a top speed of 218 mph. A typical train will have 16 cars and carry more than 1,000 passengers. With a total length of more than 1,300 feet, the new trains will be the world's longest single high-speed units in use, according to Siemens. Japan and European countries such as France have had high-speed train systems for decades. But now the race to build such trains seems to have taken off in two of the leading world economies, the China and the U.S. In the U.S., the Obama administration wants to invest $1 billion dollars a year over the next five years in high-speed rail. In addition, the stimulus bill (PDF) contained $8 billion in capital assistance for high-speed rail corridors and intercity passenger rail service. Among th…

Persiapan Pemilu 2009? KPU Sudah Siap?

Hai blogger....

Sedikit curhat nih.. mengenai persiapan pemilu RI 2009.

Dengerin radio elshinta, sekarang jam 12.58 malem... ini  masih rame orang pada ngomongin persipan pemilu. Ada yang berpendapat KPU belum siap Pemilu Diundur. Terus belum lagi permasalahan mengenai kertas suara banyak yang rusak, salah kirim tujuan dan masalah-masalah lain yang pasti selalu ada di lapangan.

Menyikapi hal tersebut, gue sih berpendapat:

Karena kita sebagai masyarakat yang awam yang mengikuti segala aturan main yang ditetapkan pemerintah hanya bisa menilai mengenai kinerja KPU itu.
Semoga saja kita berharap dan berdo'a semua yang di inginkan seluruh masyarakat dan persiapan menghadapi Pemilu yang tinggal beberapa hari lagi tetap ada di rel yang baik.


Tetap semangat teman, saudaraku..... Mari berdo'a dan bekerja bersama-sama untuk menjadikan Indonesia lebih maju dan bermartabat.

What is continuity test?

Salah satu tahapan terpenting sebelum melakukan comissioining mesin yaitu continuity test. Lebih lengkap silahkan baca artikel ini.

What is continuity?You might be asking, "What is continuity?" But don't worry, it's quite simple! Continuity means, are two things electrically connected. So if two electronic parts are connected with a wire, they are continuous. If they are connected with cotton string, they are not: while they are connected, the cotton string is not conductive. You can always use a resistance-tester (ohmmeter) to figure out if something is connected because the resistance of wires is very small, less than 100 ohms, usually. However, continuity testers usually have a piezo buzzer which beeps. This makes them very useful when you want to poke at a circuit and need to focus on where the probes are instead of staring at the meter display. For some basic circuits you can just look to see where the wires go to determine continuity but it's always wise to …

Why Use a Clamp Meter?

Mengapa mengukur Arus Listrik Menggunkan Tang Ampere?

Salah satu alat yang diperlukan pada saat kita melakukan commissioning dan pengujian arus listrik "test and run" mesin atau alat-alat yang menggunakan listrik lainnya dilapangan.

Clamp meters allow for measurement of current, without needing to disconnect the wires where the measurement occurs. By simply clamping the wire, you can get the measurement, and not cut the circuit. When using a multitester or a digital multimeter, the circuit has to be cut. In contrast, using a clamp meter, current can be measured by clamping a live wire over its sheath. In addition to its simple operation, it allows safe measurement of a higher current.Clamp meters feature low internal resistance and have both a positive and negative lead. High current flow can indicate a short circuit, a defective component, or an unintentional ground. Low current flow can indicate high resistance, or poor current flow within the circuit. Both types of c…
