1 DESCRIPTION
VAX SIMATIC 3964 for VMS is a Packaged Application Software
Solution (PASS) offering a high level programming interface
to VMS applications, to exchange data with a SIMATIC S5 system
over an asynchronous communication line. [SIMATIC is a SIEMENS
trademark; SIMATIC S5 is a family of SIEMENS systems]
VAX SIMATIC 3964 for VMS is ideal in configurations where the
SIMATIC S5 system(s) is the only type of PLC required to commu-
nicate with the VAX. In configurations with multiple device
types, and for a more generic application integration, the
BASEstar system is recommended - a SIMATIC DAS is available.
VAX SIMATIC 3964 for VMS has been designed, based on the asyn-
chronous Simatic computer link protocol as described in several
SIEMENS documents, for example:
o "Rechnerkopplung mit der Anschaltung AS-512C" (reference E324
T 19.07.83/02 Sc)
o "SIMATIC S5 - Computer link with RK512" (reference C79000-
B8576-C539-02)
Siemens has based the Simatic S5 computer link protocol on top
of the 3964 line protocol. The computer link messages exchanged
are also called telegrams. VAX SIMATIC supports telegrams with
up to 128 data bytes. Continuation telegrams are not supported.
Telegrams can be used to read or write data, and they can be
originated by the VAX or by Simatic. This renders 4 possible
data transfer modes, as seen by the VAX. 3 out of the 4 modes
are supported - the exception is unsolicited output.
o Write to Simatic, initiated by the VAX, called solicited
write.
o Read from Simatic, initiated by the VAX, called solicited
read.
o Write to the VAX, initiated by Simatic, called unsolicited
input.
o Read from the VAX, initiated by Simatic, called unsolicited
output {not supported} .
For the three supported data transfer modes, the supported
addressing modes are shown in the following table:

1.1 Features
VAX SIMATIC provides:
1. An application interface in the form of subroutine calls.
2. Include files for various languages containing all VAX
SIMATIC symbolic parameter definitions.
3. A line protocol module, called handler, which controls the
line specific initialization, implements the 3964 line pro-
tocol, and acts as a dispatcher between all applications
sharing a particular line.
4. A VAX FMS-based application which allows you to call VAX
SIMATIC subroutines without any programming effort. Also, it
can format trace files produced by VAX SIMATIC.
These are now described in more detail.
1.1.1 Shareable Image Subroutine Library
The package implements provides a set of subroutines which
are linked with the user programs. The subroutine library is
implemented as a vectored shareable image, and complies with
standard VAX calling conventions.
One application can share multiple Simatic lines. Also, a single
line can be shared by multiple applications.
Programming a solicited data transfer is similar to the use
of the VMS $QIO or $QIOW system service: the solicited data
transfer can be synchronous or asynchronous - the subroutine
call uses the same arguments. IO synchronization is achieved
with the SIMATIC VS5$SYNCH service, or with AST's.
Unsolicited inputs are always handled by means of ASTs.
Simatic application error handling uses the standard VMS error
reporting mechanism, based on a Simatic specific message file.
User data can be sent to or received from Simatic purely as
a byte string, or it can be translated depending on different
Simatic data representation formats. The following table shows
the translations available to translate VMS variables to or from
Simatic variables.

1.1.2 Include Files
The include files provided contain all parameter values as
defined by the VAX SIMATIC symbolic names. These values are also
provided as global symbols in a module in the Simatic object
library. The following languages are supported:
o VAX FORTRAN
o VAX PASCAL
o VAX PL/I
o VAX C
1.1.3 Line protocol Module
Each Simatic line is configured and managed independently.
Depending on the configuration, up to a formal maximum of 100
lines are supported.
Line problems are signalled to the OPER1 and CENTRAL operators
using the central VMS error logging facility OPCOM.

1.1.4 Utility for ad hoc interactive data access
A Simatic Utility is provided for ad hoc use or testing purposes
of the Simatic subroutines without any programming effort. It
also provides a trace reporting facility.
It can be used at the same time the line is in use by other
applications.
1.2 Documentation
All documentation for VAX SIMATIC is produced with VAX DOCUMENT,
and so various output formats are available (eg. Postscript,
LN03, Ascii text). Postscript is the default.
o The VAX SIMATIC PASS Description
o The VAX SIMATIC Installation Guide
o The VAX SIMATIC Management Guide
o The VAX SIMATIC User Guide
o The VAX SIMATIC Version 3.0 Release Notes

3 HARDWARE REQUIREMENTS
3.1 Mandatory Hardware
The following minimum hardware is required for the successful
installation and operation of VAX SIMATIC 3.0 software compo-
nents. PASS Warranty only applies if the hardware identified in
this section is present.
3.1.1 VAX Hardware
o Any VAX system.
o One RS232 asynchronous connection without modem control,
supported by the standard VMS terminal driver, on a local
line, with the exception of the VAX console line.
o One RS232 connection without modem control on a DECserver
terminal server port supported by the standard VMS terminal
driver, using the LAT protocol on ethernet . Note however
that the use of a terminal server reduces the line throughput
otherwise available on local lines.
3.1.2 SIMATIC Hardware
o A Simatic S5 processor provided with one interface module
AS-512C, CP-524 or CP-525.
3.1.3 Connection Hardware
One of the following cabling hardware can be used, depending on
the distance to cover.
o Null modem cable (BC22D or BE16D).
o RS232 to 20mA convertor.
o Asynchronous line modems.
