In that case you would need to deal directly with the European providers, possibly using a Simatic Card (prepaid buying cards used for certain transactions over the web). 60 D-91052 Erlangen Tel.: +49 91 31 7-46111 Fax +49 91 31 7-44757 E-mail: Internet: If you are located in Amwerica, note that you might have trouble getting pricing and delivery info from your local rep divisdion of certain Siemens markets and products may be strange to understand for us laymen. Your post made me look a little deeper, and here is what I found on different Siemens webpages: Siemens websites on Modbus/TCP options: Flyer: Manual: You can obtain further information on this topic at the following address: Siemens AG Industrial Solutions & Services Information Technology Plant Solutions Werner-von-Siemens-Str. Hello David I always presumed (not to say 'assumed') that Siemens did not support Modbus/TCP. Is there anybody who has already communicated with Intellisys SG controller or IRI with S7-200 via Modbus, I am very much willing to give a software authorization in return, (Step 7 V5.3 authorization!). Is this the main reason why the modbus master program is not working? You see, i'm new with modbus, it just so happened that the device that I am going to read from (the modbus slave) is an Intellisys controller by Ingersoll-Rand it has a 2-stop bit property (can not be changed!) and the S7-200 is by default a 1 stop bit device which can not also be changed. I have tried the Modbus master program but it's not working. With the MODBUS® slave protocol Instructions, you can configure the S7-200 to act as a MODBUS® RTU slave device and communicate to MODBUS® master devices. MODBUS® Protocol: The additional MODBUS® protocol library makes communicating to MODBUS® master devices easier by including pre-configured subroutines and interrupt routines that are specifically designed for MODBUS® communication. With the USS instructions, you can control the physical drive and the read/write drive parameters.

The USS protocol library makes controlling Micro-Master drives easier by including pre-configured subroutines and interrupt routines that are specifically designed for using the USS protocol to communicate with the drive. This new Micro/WIN Add-On Instruction Library adds two library folders to the STEP 7-Micro/WIN for the following communication protocols: USS Protocol: The newly improved USS protocol library supports both the Micro-Master 3 (MM3) and Micro-Master 4 (MM4) drives. 6ES7830-2BC00-0YX0) Here is a quote from their website: STEP 7-Micro/WIN32 Add-On: Instruction Library This CD adds instruction libraries to the standard STEP-7 Micro/WIN Version 3.2 programming software. Hello Siemens has an add-on product to MicroWin that they call Instruction Library Toolbox (order no.

Does anyone have library modbus master for microwin v4.0? 'SIMATIC STEP 7.
