Introduction This software allows users to create OPC UA Client and Server applications for Windows and LabVIEW Real-Time Targets. OPC UA includes many improvements over the OPC DA standard. Platform Independent Access OPC UA data from Windows, LabVIEW Real-Time Targets, and third party OPC UA clients and servers including desktop applications and PLCs.
Programmatic Configuration and Access Server and client configuration, as well as, read/write access of OPC UA tags via a LabVIEW API. Security Polcies Signed and encrypted public/private key certificates. System Requirements Desktop LabVIEW 2010 DSC Module, LabVIEW 2010 Real-Time Module, LabVIEW 2011 DSC Module, LabVIEW 2011 Real-Time Module. Windows XP, Windows Vista, Windows 7, Windows Server 2003 R2, Windows Server 2008 R2 Real-Time Targets LabVIEW 2010 Real-Time Module, LabVIEW 2011 Real-Time Module CompactRIO, PXI, Real-Time PC, CompactFieldPoint Installation Instructions OPC UA is now shipping with LabVIEW 2011 SP1 DSC and Real-Time Modules. We recommend all currently and future OPC UA development be done with the shipping version of the API. Thank you for you feedback.
Within a Modbus device, Coils (0xxxx or 9, bit, read/write), Inputs (1xxxx or 9, bit, read only), Input Registers (3xxxx or 9, word, read only) and Holding Registers (4xxxx or 9, word, read/write) are assigned an address number. You would expect that the same addressing scheme defined in the Modbus communications protocol to read or write values would be assigned to the internal registers of the device. Unfortunately this is not the case. Internal registers are used with a value between 0 and 9999. If you want to read the value of the first Holding Register (internal register 40000) for example, you have to specify the value 40001 in the Modbus query message. This leads to common mistakes and are handled in the design of the ICONICS Modbus OPC Server. In your case you should be able to use Coil address 1 to communicate to Coil internal register 0.
you have to specify the value 40001 in the Modbus query message. Robert, I have to disagree. I'm not a programmer, but I've connected a serial sniffer, and at times a scope, to figure out what was going on in Modbus message and the leading 4 in a 4xxxx address/register/memory location is not part of the Modbus message. It seems to me that the designation of address/memory/register as 4xxxx is for human-use convenience, although such a designation may, at one time in the far past actually have delineated memory boundaries. The convenience comes from knowing that 40121 uses the 03 function code, or 30099 uses the 04 function code. The function codes are associated with memory/registers/addresses by their leading numeral.
Function code 03 is associated with 4xxxx. Function code 04 is associated with 3xxxx. The leading numeral is not part of the Modbus message. The function code is.
I'm looking at function code 03 breakdown in the Modbus Application Protocol V1.1b on page 15. It omits the slave node ID at the beginning of a message and the error check CRC at the end of the message The request consists a 1 byte function code: 03 Then the starting address is two bytes, hex 0000 to FFFF.
0000 does not have a leading 4, decimal or hex. There is no 0100(h) 4 decimal leading the address. Then there's a single byte for quantity of registers, which can be decimal 1 to 125. The response echoes the function code, 03, then a byte count (in a single byte), and then provides the register values. Some Modbus masters require a leading 4 for a 4xxxx address when a human interacts with (configures) the master through its HMI or GUI or whatever, others do not and assume it. But the leading 4 does not go into the bit stream out the hardware port.
It's not part of the message. Why 03 was associated with 4xxxx and 04 associated with 3xxxx is beyond me, but that's what we live it. It provides a living, eh?

To search the site, enter your search terms in the box labeled 'search the site' and hit Enter. Some tips for better search results. Precede each search term with a '+', as follows:. +Modbus +TCP Otherwise, any post with either term will match. Use double quotes around phrases, as follows:.
+'Allen Bradley' +ethernetOtherwise, posts containing these words in separate locations will match. To exclude a word, precede it with a '-', as follows:. +Modbus -Plus This will return only posts containing 'Modbus' but NOT containing 'Plus'.
