The Cogent SST-DVN Driver for SST DeviceNet Cards (often called
the DVN Driver) is a device driver program that communicates with
SST DeviceNet cards: the 5136-DNP-ISA, 5136-DNP-ISA-2,
5136-DNP-104, 5136-DNP-PCI and the SST-DN3-PCU. The driver is
available for Linux, QNX 6, and QNX 4.
In addition to handling card input and output, with the
DVN Driver you can:
- Configure the driver without writing a lot of code.
By using a configuration file, the driver configures
itself. Or if you'd like, you can write an application
that configures the driver dynamically.
- Query the driver interactively or programmatically
for metadata on cards, data buffers, and point attibutes, as
well as for the current configuration.
- Interactively debug the fieldbus I/O via the driver.
- Join the driver to the Cascade DataHub
to immediately provide field data to applications, with no
programming.
- Access both the card's master (Group 2 client) and
slave (Group 2 server) modes, simultaneously.
- Linux users: This driver runs as a separate process
(out-of-process) from your client library. It is decoupled from
both the Linux kernel and the client. It is thus capable of
handling multiple clients.
QNX 6
QNX 4
Linux
- Linux 2.4 or later.
- The SRR IPC kernel module, which includes a
synchronous message passing library modeled on the QNX 4
send/receive/reply message-passing API. This module
installs automatically, but requires a C compiler for the
installation. You can get more information and/or download
this module at the Cogent Web
Site.
