OFS data server software
Presentation
OPC Factory Server (OFS) version 3.0 software uses the OLE for Process Control
(OPC) standard, allowing "Client" software applications (supervisors, databases,
spreadsheet programs) to access the following data:
b Internal variables (words, bits) and inputs/outputs of Modicon Premium/Quantum
PLCs.
b Internal variables (words, bits) of Modicon TSX Micro PLCs, Modicon
Momentum/Quantum PLCs (1), TSX Series 7 and April PLCs.

OFS software is a multi-PLC data Server that enables several communication
protocols to be used by providing Client application programs with a set of services
for accessing the control system variables.
This software is aimed at two types of user in particular:
b “End” users who seek to develop applications on a PC and require access to PLC
data. In this context, it is possible, for example, to create Client applications
(supervisory control screens, Excel tables, etc.) with access to a number of PLCs
connected to the PC supporting these applications.
b “Suppliers” of control system or industrial data processing products (supervision,
Human/Machine Interfaces, etc.) seeking to develop, within their standard products,
an OPC Client application capable of accessing data stored in PLCs via the OPC
Server.
The OFS offer comprises:
b A tool for configuring the OPC Server.
b An OPC Server software application that receives requests from an OPC Client
and retransmits them to the PLCs.
b Low-level drivers for communication with Modicon PLCs.
b An OPC Client enabling verification of Client/Server communication between the
various connected elements.
b A simulator enabling verification of operation of one or more Clients, without a
connected PLC.
b The electronic setup documentation.
