The other four connections can be used by any MPI master. Your use of this site is subject to the terms and conditions set forth under Legal Notices and the Privacy Policy. Use Siemens’ support website: David, Here are some pointers. The EM can be configured by the DP master to accept output data from the master and return input data to the master. PNP transistor not working 2. If you are using a non-Siemens master device, refer to the documentation provided by the manufacturer on how to configure the master device by using the GSD file.

The slave only accepts write requests from the master that owns it. GSD at website www. A in the above manual, where more details on the setup of thwe EM can be found.

By Anonymous on 11 July, – 6: These parameters vary for each device type and vendor, and are usually documented in a technical manual. Additional Assistance For assistance in answering technical questions, for training on this product, or for ordering, contact your Siemens distributor or sales office.

Dec 242: The time now is What is the function of TR1 in this circuit 3. Input data to the master are transmitted to manuall master on the next data exchange with the master. The station address is set with the rotary switches on the EM module. S S Byte consistency ensures that bytes are transferred as whole units.


Distorted Sine output from Transformer 8. The default configuration for the EM module is two words of input and two words of output.

Output data from the master is only written into V memory when there is new data available from the master. Inputs, counter values, timer values, or other calculated values can be transferred to the master by first moving the data to the variable memory in the S CPU. How reliable is it? Both the DP master and the DP slave use the data consistency selection to be sure that data values bytes, words, or buffers are transferred uninterrupted within master and slave. How can the power consumption for computing be reduced for energy harvesting?

Manual for the EM – Entries – Forum – Industry Support – Siemens

To exclude a word, precede it with a “-“, as follows: Buffer consistency ensures that the entire buffer of data is transferred as a single unit, uninterrupted by any other process in the CPU.

The default address for the input and output buffers is VB0. Help keep our servers running Word consistency ensures that word transfers cannot be interrupted by other processes in the CPU. By David Alvarez Quiroga on 12 July, – 9: Use the following tools to configure the DP master: Synthesized tuning, Part 2: CMOS Technology file 1.

Use double quotes around phrases, as follows: This feature allows you to tailor the amount of data transferred to meet the requirements of the application. Buffer consistency should be used if the data values are double words or floating point values.


This information is used in the program the copy the data in the DP output buffer to the process-image output register of the CPU Likewise, data from the master is stored maanual variable memory in the S CPU and can be moved to other data areas.

By brian on 12 July, – If this is not maual, have a look at App. Hierarchical block is unconnected 3. The input data to the master is taken from the V memory at V Username Password Remember me on this computer.

Note that common words and, that, etc. By Daniel Chartier on 10 July, – 6: The master is also told where to place data that is read from the slaves inputs and where to get the data to write to the slaves outputs.

If you’re not already a member, consider joining. Select the categories for which you would like to see messages displayed Part and Inventory Search.

The slave devices can notify the master if there is an exception condition and the master then reads the diagnostic information from the slave. The location of the input and output buffers is part of the parameter assignment information that the master writes to the S CPU. Sending variables from S to S via EM I have used the EM many times, it works well and is excellent value for money. Dec 24kanual
