ISAX Modbus RTU ActiveX Developer version Publisher's Description

ISAX Modbus ActiveX provides communication with PLCs, instruments and many other devices which can act as standard Modbus RTU slave stations.
The control can execute Function Codes nr. 1, 2, 3, 4, 5, 6, 7, 15, 16 of Modbus RTU specifications.
Communication can be direct or multidrop.
ISAX Modbus is the best low cost solution to build up your own supervisoring application using the platform you prefere (Office, VB, VC++, etc.).

Release Note of version 3.0
Starting from version 3.0 ISAX Modbus can be used both in singleport or multiport configuration; this means that developer has not to insert more than one ActiveX in his application if protocol must operate on more ports!! All commands can be direct to a specified port or to the default one. Protocol has been improved adding new events, optimizing the speed in communications and extending the capability of controlling ports identified with number greater than 16. For more information check the manual included in download.

Release Note of version 3.1
Parameters have been added to events to identify Slave Address and/or port number where error occurred.

Release Note of version 3.2
Added methods for reading/writing 32-bit data types (both long integer and floating points data), with word/byte swap, in order to enhance the flexibility of the driver.
Enhanced error reporting in methods.
Fixed a bug that could create problem opening ports with a identification number greater than 10.
Communication speed has been further increased, eliminating any delay between master request and slave response.
