Packaged Application Software Solution Description (PASSD)
VAX DECsicon, Release V.2.0
Packaged Application Software Solution
(PASS)
1 DESCRIPTION
VAX DECsicon is a Packaged Application Software Solution (PASS)
offering a call interface with a communication path to external
equipment using a serial line and the RK512 protocol (S5 Re-
lated) layered on top of the 3964 (3964R) procedures. Commonly
used external equipment are Siemens SIMATIC S5 series PLC's and
TELEPERM M controllers.
To achieve high data througput and low CPU load, the external
equipment is connected to a serial line of a KXJ11-CA single
board computer which in turn is used as an intelligent I/O
preprocessor (slave) of the MicroVAX host. Physically the KXJ11-
CA is plugged into the MicroVAX Q-Bus.
1.1 Features
VAX DECsicon provides:
o Serial lines with the following configuration parameters:
o Supported baudrates: 150, 300, 600, 1200, 2400, 4800, 9600
o One startbit
o Eight databits
o Two stopbits
o Even parity
o A subroutine library with four routines for the programmer to
support the application development. The calls are:
o KXJ$ASSIGN to connect to one serial line of a KXJ11-CA.
o KXJ$IO to initiate various I/O functions and complete
asynchronously.
o KXJ$IOW to initiate various I/O functions and complete
synchronously.
o KXJ$DEASSIGN to disconnect from one KXJ11-CA serial line.
o A test utility to facilitate rapid prototyping of DECsicon
applications. Using the utility it is possible to connect to
a serial line, change characteristics of the line, write data
to and read data from the line and disconnect again from the
line.
o An example of an application written in VAX/VMS FORTRAN.
o Definition files for FORTRAN, PASCAL and C
The following table gives the QIO function types compared with
the corresponding SIEMENS Telegram type.
