'Normal' mode requires that the OIT be connected to the computer and that the PLC be connected to the OIT.
'Direct' mode requires only that the PC be connected to the PLC. Please note the following:
Maple Systems' standard communication cables will not work in Direct mode. The 'OIT' end of the cable
must be wired for the PC's serial port.
To simulate protocols using RS422/485, an RS422/485 card must be installed in the PC.
The Allen Bradley DH485 and Telemecanique UniTelWay protocols are not supported in Direct mode.
The On-Line simulation mode is selected in EasyManager, by checking or unchecking the Direct Online-Simulator
box. Whether started from EasyBuilder or EasyManager, the Online-Simulator will operate in the mode selected by
the Direct Online-Simulator box.
On-line simulation is most useful when a project is near completion and you need to test the interaction of the
project with the PLC. It is also very convenient when making minor changes to a project because these changes can
be instantly checked for operation. When 'normal' on-line simulation is used, the computer interrogates the PLC
through the OIT to access any data required. When 'direct' on-line simulation is used, the computer interrogates the
PLC directly.
Off-line simulation does not require any connection to the OIT. Because of this, off-line simulation is most often
used when starting a project. You can quickly test new ideas and create preliminary screens without the OIT.
Off-line simulation is also great for demonstrating the operation of the OIT and becoming familiar with the
operation of the OIT before it is installed. If you want to simulate the interaction with a PLC when off-line, it can be
done by creating additional windows on the OIT which allow PLC data input.
To use off-line simulation mode from EasyBuilder:
1. If the project has been modified since the last time it was saved and compiled, or if it has not
yet been compiled, it must be saved and compiled before the simulator can start.
2. From the Tools menu, click Off-line Simulation or click the Off-line Simulation icon in the
Standard toolbar.
3. The Simulation Mode screen should appear.
4. To end off-line simulation press the Space bar or right click in the simulation screen and click
Exit.

Exit.
Simulation mode can also be started from EasyManager. EasyManager requires only the compiled project file
(*.eob). This can be useful in situations in which you want to demonstrate changes made to a project for a client
without giving him access to your project file. It also allows you to rapidly switch from simulating one project to
another without having to open, save, and compile each project.
To use off-line simulation mode from EasyManager
1. Start the EasyManager software.
2. Click Offline-Simulator. The Open Project box appears.
3. Click on the compiled project file that you wish to simulate.
4. Click Open. The simulation screen should appear.
5. To end off-line simulation press the Space bar or right click in the simulation screen and click
Exit.
