5.5.2 Simulation of a Project
Function
The scope of delivery in respect of the ProTool/Pro RT runtime software contains a
simulator with which to test the project without a PLC. The simulator is a separate
application. It enables the user to test whether the screens, screen objects,
messages, etc. which have been configured function correctly.
The simulator simulates the PLC and
S modifies the values of configured tags in a definable way:
e.g. incrementally, decrementally, sinusoidally, randomly or by shift bits
S sets bits in bit-by-bit organized area pointers
1)
:
By shifting the bits in the two area pointers
Event Messages
and
Alarm
Messages
, it is possible, for example, to trigger all the configured messages on
the operating unit.
A condition for simulation is that the ProTool/Pro RT runtime software is also
installed on the configuration computer.
Principle
The following steps describe the basic procedure for simulating a project.
Step-by-step instructions are provided in Table 5-1.
1. First of all, create a project as is to run later when connected to the PLC.
2. Save and compile the project.
3. Start the simulator directly from the running configuration software by
clicking on the icon depicted or via menu options
File
Test
Start Simulator
.
If the simulator is started without having compiled the project beforehand,
compilation is automatically triggered.
4. When the project is simulated for the first time, the simulator is started with a
new, empty simulation table. If a simulation table already exists for the project, it
is opened.
All the settings are saved in simulation table *.sim defined for the simulation of
tags and area pointers (refer to Figure 5-1).
5. Now manipulate the project tags and area pointers in the simulation table.
6. It is possible to watch how the values change by switching the task from the
simulator to the project.
1) The simulator can simulate bit-by-bit organized area pointers (except trend transfer area), e.g. event
messages and alarm messages. The simulation of byte-by-byte oriented area pointers (e.g. data
mailbox or PLC job) is not possible.
