SuperCom MODBUS Protocol Library
MODBUS is an industrial data communication protocol used to control PLC's and automation machines connected through serial lines (RS-232, RS-422, RS-485) or Ethernet TCP/IP connections. The SuperCom MODBUS Protocol Library supports send and receive data with one or more devices which respect the MODBUS protocol.
The SuperCom MODBUS Protocol Library is the most complete MODBUS library and provides a rock solid foundation to develop fast robust MODBUS capable applications. The SuperCom MODBUS Protocol Library hides the complex MODBUS protocol offering one easy to use set of functions that can communicate data packets over serial and TCP/IP connections thus saving valuable time, reducing costs and ensuring quality results.
Perform easily master or slave device functionality in you application written for example with C++, C#, Delphi, Visual Basic (incl. NET), Java etc.
The SuperCom MODBUS Protocol Library supports data communication between devices connected to a serial port, on a bus system or network (TCP/IP). The protocol module supports ASCII and RTU (Remote Terminal Unit) operation mode (ASCII mode transfers ASCII codes and RTU binary data bytes in binary mode).
Run up to 255 simultaneous connections with Modbus devices.
There is only one API to learn! The same functions used with Serial, TCP/IP or ISDN type of connections and operation mode (Modbus ASCII, Modbus RTU, Modbus TCP).
The SuperCom MODBUS Protocol Library also supports custom function codes and data packets by implementing functions that communicate transparently. Controlling machine specific extensions is realy easy using these functions.

- Runs smoothly even if multiple concurrently executing connections.
- Run multiple Modbus masters.
- Offers short reaction times.
- Connect one or more MODBUS RTU or ASCII masters to one or more Modbus slaves.
- The SuperCom MODBUS protocol module can control, based on the used SuperCom software, serial and/or TCP/IP connections.
- The SuperCom MODBUS protocol module can run concurrently connections thus polling more than one plc the same time is possible.
- Receive Modbus data packets and simulate one or more MODBUS slaves or Protocol Gateway.
- Create your own Modbus Gateway or Bridge to route data between serial interface and TCP/IP network, for example a MODBUS TCP to MODBUS RTU Gateway.
- Use SuperCom for Modbus bridging (e.g. serial to TCP/IP).
- Create your own Protocol Gateway using one of the other SuperCom industrial protocols (PLC protocols) offered or use your own custom protocol.
- Create your own Modbus Slave that can handle requests on its own or handed over to the application (manual mode) or mixed. A Modbus Slave, created with SuperCom, can support up to 254 concurrent client connections.
- Use with PLC from SIEMENS, Allen Bradley, other Modbus capable PLC, Modbus devices and controller. A pre-installed MODBUS protocol module on PLC or connected controller or device assumed.
- Receiving and transmitting of Modbus raw data is supported
- Low level Data monitoring and recording also supported.
The SuperCom MODBUS Protocol Library uses the SuperCom Communication Layer which provides a rock solid foundation to develop data communication software fast and without headache. Thus it makes no difference to the programmer if the MODBUS protocol used over TCP/IP or serial lines (RS-232, RS-422, RS-485, Modem, TAPI).
SuperCom enables the application to connect to a PLC (nearly from anywhere, e.g. Modem, TAPI, ISDN, Ethernet (TCP/IP), serial lines e.g. RS-232, RS-422, RS-485) and transfer data and/or read, write operands.

Capture, Store, Forward - MODBUS Slave or Gateway functions
Communication at lower data packet level is possible thus allowing to capture, store and forward of MODBUS data packets or transmit replies. Monitoring MODBUS data packets, simulating a MODBUS Slave or building a protocol converter / gateway is possible. Simulating a MODBUS Slave can be very handy while testing the software (slave examples available).

Serial Parameters are parameters that modify the way the MODBUS frame is structured. Refer to the MODBUS specification for more information about the MODBUS Frame. The Serial Parameters in LabVIEW is a cluster containing an enum (Mode) and an integer (Slave Address). Mode RTUData is represented in binary format. ASCII Data is represented in ASCII, so it is human readable. Slave Address This is the address of the slave you are communicating with. This property is usually valid for RS-485 networks, which can have multiple MODBUS devices connected to the same network. Note: Consult your device documentation to find out how to validate/change the address of your device. | ||||||||||||||||
VISA resource name specifies the resource to be opened. This control also specifies the session and class. For more information about VISA resource names, refer to the NI-VISA Help. | ||||||||||||||||
Starting Address is the first address location of the holding register to read. This address is sometimes referred to as offset. Refer to your device's documentation to find the holding register address mapping. Be sure to specify the correct address in the MODBUS device configuration software for the register you want to use in LabVIEW. In most MODBUS device configuration software, you must enter a name for the register you want to use. Per MODBUS convention, the register address of the slave device is calculated by subtracting 1 from the register name that you specify in the master device configuration software. The MODBUS LabVIEW library expects register addresses, not register names, so you may need to subtract 1 from the address you defined in the MODBUS device configuration software. For example, a register name defined as 2 in a MODBUS configuration device translates to register address 1 in the Holding Registers table of the LabVIEW MODBUS library, as shown below.
| ||||||||||||||||
Quantity represents how many holding registers to read from the slave. The VI returns the holding register at Starting Address and each following holding register up to Quantity.For example, if Starting Address is 0 and Quantity is 4, the VI reads holding registers from the slave at address 0, 1, 2, and 3. | ||||||||||||||||
Timeout specifies the maximum time period, in milliseconds, that the VI waits for the slave's response before throwing an error. | ||||||||||||||||
error in describes error conditions that occur before this VI or function runs. The default is no error. If an error occurred before this VI or function runs, the VI or function passes the error in value to error out. If an error occurs while this VI or function runs, the VI or function runs normally and sets its own error status in error out. Use the Simple Error Handler or General Error Handler VIs to display the description of the error code. Use error in and error out to check errors and to specify execution order by wiring error out from one node to error in of the next node.
| ||||||||||||||||
VISA resource name out is the resource to which a VISA session is opened and its class. The class matches that of the VISA resource name input. For more information about VISA resource names, refer to the NI-VISA Help. | ||||||||||||||||
Holding Registers represents the data read from the slave (array of U16). | ||||||||||||||||
Exception Code is nonzero if a MODBUS error has occurred. The exception code mapping is as follows:
| ||||||||||||||||
error out contains error information. If error in indicates that an error occurred before this VI or function ran, error out contains the same error information. Otherwise, it describes the error status that this VI or function produces. Right-click the error out front panel indicator and select Explain Error from the shortcut menu for more information about the error.
