Does anyone have library modbus master for microwin v4.0? 'SIMATIC STEP 7. But i need for master. S7-200 library uss + modbus slave.
Re: LINK: Modbus Tools 2010 - Modbus Poll 5.0.1 - Slave 4. Post by lbzu » Sun Nov 04, 2012 2:21 am New Version Modbus Poll 5.5.0 Build 657 and Modbus Slave 4.6.1 Build 641. Modbus-ASCII (AsciiPort): Over serial line require node serialport. Client TCP: modbus-TCP (TcpPort): Over TCP/IP line. Modbus-RTU (UdpPort): Over C701 server, commercial UDP to serial bridge. Modbus-RTU (TcpRTUBufferedPort): Over TCP/IP line, TCP/IP serial RTU buffered device. Modbus-RTU (TelnetPort): Over Telnet server, TCP/IP serial bridge. Slave 1 Slave 2 Master (DCS) Slave 3 Slave 4 Modbus Figure 1.1 Modbus configuration The master can send a query (i.e. Poll) or command to a slave on a regular basis or when required. In either case, the master starts signal transmission and the slave responds. F0102.ai Master Device number Command message Response message Function.
Hello; Siemens has an add-on product to MicroWin that they call Instruction Library Toolbox (order no. 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. 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. 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. With the USS instructions, you can control the physical drive and the read/write drive parameters.
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 MODBUS® slave protocol Instructions, you can configure the S7-200 to act as a MODBUS® RTU slave device and communicate to MODBUS® master devices. Hope this helps, Daniel Chartier. I have tried the Modbus master program but it's 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. Is this the main reason why the modbus master program is not working?
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!). How about that? Thanks a lot.

Hello David; I always presumed (not to say 'assumed') that Siemens did not support Modbus/TCP. 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. 60 D-91052 Erlangen Tel.: +49 91 31 7-46111 Fax +49 91 31 7-44757 E-mail: it4industry@siemens.com 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. 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). Thanks for the new comm. Oppertunities, Daniel Chartier. Daniel, Thanks for tracking that info down, it should help it trying to purchase this library.
My Siemens Rep. Said, 'Since it's very pricey for one thing but also it's not readily available/supported here in the US.' He went on to say there might be shareware versions meaning customers had made there own custom implementation of Modbus TCP. Its very feasible to write a custom protocol with FB50 and FB60.
I was hoping someone else has been down this path and might have a working example to share. I really only need to implement a simple class 0 master or slave.
diagslave is a simple command line based Modbus slave simulator and test utility.diagslave is using the FieldTalk™ Modbus driver.
Diagslave binaries are available for the following operating system platforms and architectures:
- Windows PCs
- Linux PCs
- Raspberry Pi, BeagleBoard and other ARM based Linux devices
