General:

Modbus for Windows provides an interactive tool for development, data acquisition, monitoring, and testing of systems employing the MODBUS protocol. This tool provides the interface between the serial port connected to the MODBUS device and the Window's environment.

Environment:

IBM or clone computer with a 386 microprocessor or higher. Window's version 3.1 or higher (both 16 and 32 bit versions available). Serial port for each Mdbus instance. 3.5 inch floppy drive for installation.

Configuration:

Fully configurable via drop down menus - start and number of data type. Unique configurations can be defined, saved, and reloaded. Multiple instances can be invoked.

Operation:

MODBUS RTU or ASCII protocol. Separate display window for each data type.

Master Simulator:

Permits polling of designated slave unit. Indicates current communication status. Maintains communication statistics. Function codes one to four used for data acquisition, five and six for control. Supports modem dial out with AT command set. Received data can be printed. Displays TX and RX messages in monitor Window for communications testing.

Slave Simulator:

Responds to function codes one to four with user specified data. Function codes five, six, fifteen, and sixteen are displayed on a control window. Automatic pertubation of data for Host alarm and trend testing. Displays TX and RX messages in monitor Window for communications testing.

Monitor:

Permits viewing of MODBUS data passed between devices. By diode coupling, the Tx and Rx lines can be monitored. Selective messages can be configured for viewing. Selection can be based upon Slave number, CRC error, or function. Received messages can be logged to file.

Host:

Permits polling of up to 32 different Slaves or configurations. Individual Poll Statistics are kept. Data from all Slaves can be dumped into Excel with one DDE Poke.

Excel Interface:

Direct DDE link via poke. Excel macros may be used to control and configure MDBUS.

DDE Interface:

Programs with DDE support can request data from simulator. This includes applications such as Microsoft Excel, Access and Word.

Modbus RTU/TCP Communications:

Communicate via the Internet or LAN to devices or applications which support the Modbus RTU/TCP protocol.  In this mode, Mdbus will function as a Master or Slave.

Optional OPC Server:

Mdbus is now available in two versions  One without the OPC Server Option (3.54) and one with (4.01).  Calta will continue to upgrade revisions for free.  However, upgrades from a non OPC version to the OPC version will cost $50 USD.

Latest version with OPC - 4.01 2008-June-21. 
Latest version without OPC - 3.54 2008-June-21.

Addition of Master func. 8 poll (Return Data Query only), ability to log Monitor Window to file in Master/Slave modes.
