 The above method will work with a standard PC serial COM port, regardless of the COM number assigned to
the PC serial port. EZwarePlus supports RS232 communication on ports COM1 – COM9. COM4 and higher are
intended for use with online simulation only, since the HMI5000P itself only supports RS232 communication
on COM1 – COM3. The L and HD Series support RS232 on COM1 only.
 If simulating with RS422 or RS485 communication, the PC will require some mechanism to support
RS422/485. A communication card can be installed in the PC, a USB communications module can be used, or
an external RS232-to-RS485 converter can be used. In any case, a standard Maple Systems cable may not
work.
If simulating a project using Ethernet communications, an Ethernet cable between the PC and the PLC/controller is
needed. Consult the PLC/controller documentation for details.
 To use EasySimulator
Online or offline simulation can be initiated without having to open EZwarePlus or Utility Manager by using
EasySimulator. EasySimulator is located in the same folder as EZwarePlus and Utility Manager
(C:\MapleSystems\EZPlus\EasySimulator.exe). If you have installed the EZwarePlus Downloader, it is located at
C:\MapleSystems\EZPlusUtil\EasySimulator.exe.
When EasySimulator starts, it reads the file “XOB_POS.def,” which is also located in the same folder as EasySimulator.
This definition file determines whether to run offline or online simulation, the location of the com.exe and gui.exe
files, and the location and name of the *.xob file to simulate. The following are the default settings for the
XOB_POS.def file:
// mode – 0: offline, 1: online
“0”
// directory containing com.exe and gui.exe
“c:\MapleSystems\EZPlusUtil”
// xob file
“c:\MapleSystems\EZPlusUtil\HMI5121PDemo.xob”
Edit the XOB_POS.def file in a text editor such as Notepad. See Technical Note 5053, “Using EasySimulator” for more
information.
Now that you are familiar with using simulation mode, the next chapter guides you through the fundamental
operation of three primary segments of the EZwarePlus configuration software.
