There is alternate writing to the holding register of the slave (function code 16) and reading from the holding register of the slave (function code 03). We have taken the example of MODBUS communication between a master and a slave. We will take a sample project to describe the configuration procedure in STEP 7 (TIA Portal) V11 for communication with multiple slaves using the CM 1241 RS485.

With up to 32 slaves one after the other using the RS485 (via CM or CB 1241 RS485).

With only one slave using the CM 1241 RS232 (physical limitation).

If you select MODBUS Master, you can communicate Using the MODBUS library integrated in STEP 7 (TIA Portal) you can define each communication module as a MODBUS master or slave. You can add up to three communication modules (+ one RS485 communications board) to each PLC Siemens S7-1200 controller. The PLC Siemens SIMATIC S7-1200 enables point-to-point communication via the CPU extension with the interfaces RS485 und RS232. sebenarnya dari versi sebelumnya bisa dilakukan tetapi semuanya tidak free, sekarang di plc siemens S7-1200В sudah bisa langsung dilakukanД«erikut kutipan yang di ambil dari web resmi support siemens

PLC Siemens umumnya mengalami kesulitan dalam koneksi modbus, khusunya ke peralatan dengan modbus serial seperti power meter, protection relay dan lainnya. I really only need to implement a simple class 0 master or slave.A MODBUS-RTU communication with PLC SIEMENS SIMATIC S7-1200? I was hoping someone else has been down this path and might have a working example to share. Its very feasible to write a custom protocol with FB50 and FB60. 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. Daniel, Thanks for tracking that info down, it should help it trying to purchase this library. 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 MODBUSВ® slave protocol Instructions, you can configure the S7-200 to act as a MODBUSВ® RTU slave device and communicate to MODBUSВ® master devices. MODBUSВ® Protocol: The additional MODBUSВ® protocol library makes communicating to MODBUSВ® master devices easier by including pre-configured subroutines and interrupt routines that are specifically designed for MODBUSВ® 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.
