Modbus Master OCX...
Master-Mode Control for Visual Basic
is a powerful custom control providing drop-in support for
accessing data from any number of Modbus slave devices into
Visual Basic applications. The Modbus_Master Control allows the
application to connect to multiple COM ports, modbus/TCP servers and/or
modem devices to read and write data contained therein. The control
takes care of all modbus message formatting and interaction with the Windows
COM and network drivers. All the application has to do is request a read
or write operation to range of addresses in a connected slave device and the control
will take care of transfering the data and provide an event back to the application
detailing the results.
Modbus Slave OCX...
Slave-Mode Control for Visual Basic
is an extremely easy to use custom control that allows your application
to expose data to any connected modbus master via one of the PC's COM
ports or via the network using modbus/TCP. This control is the quickest
possible route to implementing a modbus slave design on a Windows platform.
Detailed knowledge of the modbus protocol is not required and no programming
is necessary to support interaction with the Windows COM or network drivers.
Your application simply supplies a pointer to one or more
blocks of data and the ocx takes care of all the rest.
WinTECH Software can provide both Master & Slave MODBUS drivers for
either the 16 or 32-bit Windows platform, (as well as the PocketPC). These drivers are in the
form of dll's and are written in straight 'C' code.
Each dll interacts with your application using a simple API function
set to read & write MODBUS data points. The dll handles all MODBUS
message formatting and interaction with the Windows Serial drivers.
An expanded version of each dll is available for the Win32 platform which
includes support for modem, (TAPI), and network connections, (MBAP).
Each dll is supplied in source form. An example application,
(written using the Microsoft MFC), is supplied with each version
of the dll. Please review the Licensing Agreement
for details concerning use and redistribution of the code.
Refer to the list below for pricing information. A description of the
API calls for each dll is available by clicking on the associated part
number. All modbus source code supplied by WinTECH Software has an unconditional
30-day money-back gaurantee. If, after receiving the code, you are
not satisfied, simply discontinue use, remove the code from your possession,
and notify WinTECH Software within
30 days. The purchase price will be refunded, no questions asked.
