APPLICATION
The PD 3930 is a communication module, providing an interface from the P-NET
fieldbus to PC’s running the Microsoft Windows 95/98/NT operating systems. The module has a
parallel port interface, enabling any standard desktop, laptop or single board PC with
parallel port to be connected to the P-NET fieldbus, and hence be used in applications such as
process and factory automation, machine control, data acquisition etc.
SYSTEM DESCRIPTION
The PD 3930 PC P-NET interface module provides an interface between the P-NET
Fieldbus and a standard PC running VIGO version 4.00 or higher. It is connected to P-NET via
a shielded 4-wire twisted pair cable, and has a built in DSUB/25 male connector for connecting to
a parallel port on the PC.
Power to the module is supplied either by means of a mini jack connector, or via
the twisted pair cable also used for P-NET connection. If supplied by means of the mini jack
connector, power might be able to be supplied from the PS2 connector for mouse or keyboard on the
PC, provided the PC is able to deliver 350 mA at 5V (400 mA at power up).
The PD 3930 is connected to the PC via a standard IEEE 1284 parallel port. It
can be plugged directly into the parallel port, or by means of an IEEE 1284 approved cable with
a maximum length of 1.5 m.
The PD 3930 can act as a P-NET master
and as a P-NET slave. The module has 2 channels, - the Service Channel (channel 0) and the Communication Channel (channel 1).
The Service channel, which is mandatory in all P-NET modules, holds general
information about the module, such as ID, serial number, P-NET node address and error status of
the complete module.
The Communication channel holds all data applicable to the P-NET port set up
(P-NET node address, baud rate etc.). The Communication channel also holds the error status
of the channel. Errors reported include configuration errors, communication errors and module
errors.
