Modbus is a serial communication protocol. You may get a response if you post your questions on the NI Community Forums. Note: The unsupported Modbus Libraries are not supported by NI. This library may not contain as many features you need as the LabVIEW Modbus API or the supported API included with LabVIEW DSC Module. Programming with it requires some knowledge of Modbus function calls to program. The Modbus Library for LabVIEW is a wrapper for VISA commands.

It is intended as a replacement and expansion of the free Modbus library functionality that supports versions of LabVIEW before 2012. The LabVIEW Modbus API is the latest release of the free LabVIEW Modbus Library. Unsupported Modbus Library (boxed in green in the screenshot above) To learn more about using DataSockets to connect to OPC Servers, take a look at the tutorial on connecting LabVIEW to an OPC server using front panel DataSockets. If you do not have an OPC Server, NI OPC Servers provides an interface to many protocols, including Modbus. If you are using LabVIEW on Windows, you can also use DataSockets to communicate with an OPC Server that can communicate with Modbus. The supported Modbus API is included in the LabVIEW DSC Module and the LabVIEW Real-Time Module. Everything must be done manually when using this low-level API. The supported Modbus API provides fine control over the Modbus protocol, with high performance. Supported Modbus API (boxed in blue in the screenshot above) In exchange for ease of use, Modbus I/O Servers do not have the fine control that the supported LabIVEW Modbus API has over the Modbus protocol that can be required for some applications. Modbus I/O Servers is included in the LabVIEW DSC Module and the LabVIEW Real-Time Module. Modbus I/O Servers provide a simple way to access and write Modbus data in LabVIEW. I don't know what may be the problem, but seems to me that the OPC server doesn't have an access to the PLC (the NetToPLCsim and the PLCsim).The Modbus I/O Server allows you to easily link Modbus register values to Shared Variables that you can use in your LabVIEW VIs. "Online: Connection could not be established the connection partner is not responding" On the a right click on the index 125 of the Station configuration editor ( Stationmanager) and then on "diagnostics" I got the message: The OPC server and IE general that I use are the version 8.1. "Could not log off the proxy with index 125 from the SoftBus"

In the Station Configuration manager I have message: When I start the OPCscout and try to run a OPC.SimaticNet server and a OPC UA server I got the messages (see an attachment).

On the second virtual machine I have a OPCserver (with imported xdb file) and IP address configured in the netpro and a PG/PC interface is set to PC internal. On the first virtual machine I have a PLCsim and a NetToPLCsim, the PLCsim and the network have the same IP address and I have found the in the NetToPLCsim and have them started, the PG/PC interface is set to PLCsim TCP/IP. Hi, I did the configuration you explained using two virtual machines and I can ping one from the another. In that document I use the option to add a second IP address to your interface, but you can simply change the IP address.

I've written a document of how to setup a simulation with Simatic Net OPC server and Plcsim/Nettoplcsim (file SimaticNet-OPC-mit-Nettoplcsim.pdf), but it's only in german available:

If in your example the computer with Plcsim/Nettoplcsim has the IP 192.168.1.4, then in your NetPro Setup, the PLC which is the destination of the S7connection you hav configured must have the IP 192.168.1.4. If you want to connect the Simatic Net OPC server to Plcsim/Nettoplcsim, you must run them on different computers (or use a virtual machine).

I don't know why, but the Siemens OPC server does not like this, with other OPC servers this is no problem. Running Simatic.Net OPC server and Plcsim/Nettoplcsim on the same PC does not work, as the OPC server then has to connect to the machine where it is running (localhost).
