Communication Server
Overview
The SPA Bus Communication Server (hereafter referred to as the “SPA Server” or
“SPA” or “Server”) is a Microsoft Windows application program that acts as a
communication protocol server and allows other Windows application programs to access
to data from SPA bus devices. The SPA bus consists of one IBM PC or compatible
computer as a master and several slaves. The IBM PC is connected to the physical SPA
bus via serial communication using Bus Connection Module. For fibre optic connections
the SPA-ZC 22 unit can be used. The interface to Bus Connection Module can be RS-
485 (RTS lines must present) or RS-232. If RS-485 is used then RS-232/RS-485
converter (e.g., OPTO22 AC7A/B Adapter Card) or IBM serial adapter card (e.g.,
OPTO22 AC37 Remote Bus Adapter Card) can be used. The Server is also capable to
communicate with SACO 100M device. In this case there is no need for the RS2-32/RS-
485 converter.
There are two different SPA Server versions described in this manual:
- Server version (ordering number DR 120 10) supporting SuiteLink, FastDDE and DDE
protocols; this version hereafter is referred to as the “Suite Link & DDE” version.
- Server version (ordering number DR 120 11), supporting OPC and DDE protocols;
this version hereafter is referred to as the “OPC & DDE” version;
The separate installation package is supplied for each version of the Server. In all cases
the name of Server executable file is SPA.EXE. All further information in this manual is
same for all versions of the Server, with the exception of few points where communication
protocol specific features are explained.
