5.1 MORE ABOUT ISAGRAF
5.1.1 Project Manager
The ISaGRAF methodology begins with the preparation of a detailed project specification. This step is
common to all PLC programming techniques and is usually the result of a thorough analysis of the project
and consultation between the integrator and the user.
Distributed applications can be represented as several ISaGRAF projects grouped together in the project
list. Distributed applications can be edited, simulated or debugged on the same Windows screen.
5.1.2 Program Manager
With the program manager the application specification is divided into smaller functional modules. The
exact operation that is to be performed within each module is defined at that stage.
ISaGRAF’s program management facilities allow the user to define each of these modules, their
operations and their interaction to form the complete application.
5.1.3 Variable Definition
All variables are declared or imported in the ISaGRAF dictionary. When this step is achieved, during
programming, a mouse click will insert the variable in the program.
Any external database can be imported to build the ISaGRAF dictionary. A quick declaration allows many
variables to be declared with one command and an easy to use mapping tool is provided for Modbus-
based SCADA systems such as Indusoft?. For a brief description about Indusoft and how to use it in
conjunction with EMBEDDED PLC see Chapter 9.
The EMBEDDED PLC Firmware Kernel implements three types of Modbus communication: Modbus over
TCP/IP, Modbus RTU over RS232 and Modbus RTU over RS485. The EMBEDDED PLC Kernel can run
only one protocol at one time.
Note:
EMBEDDED PLC has the TCP/IP port 502 reserved (this port can not be modified) to support Modbus
over TCP/IP communications. Since ISaGRAF Workbench uses a different TCP/IP port for
communication with the Target PLC (port 1100), the Workbench and a Modbus master (HMI or
SCADA) can communicate with the Target at the same time, i.e. when the Target is configured as
Modbus over TCP/IP the ISaGRAF Workbench and a Modbus master can share the same physical
line (Ethernet). However, when the Target is using either RS232 or RS485 only an ISaGRAF
Workbench or a Modbus master can be connected to the target at any one time.
5.1.4 Functional Module Programming
The next step in the ISaGRAF methodology is the actual programming of the various functional modules.
This can be done using any one of the six supported languages:
