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!). 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. I have a Siemens S7 -200 PLC that I would like to test using ModBus RTU but unfortunately I don't have a library for MicroWin. I'd like to receive news and commercial info from Schneider Electric and its affiliates via electronic communication means such as email. 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.ĭownload: PLCOpen library for Siemens S7 - Lexium 32 & Motors, SIGN UP FOR EMAIL.
