Maple Systems MAPware-100 - Manual (Page 27)

Notice that COM Ports 1 through 4 are supported, although most machines typically have
COM1 and COM2. The port needs to be set once.
Three options are available to determine how the project information is to be sent to the OIT. The
Project, Operational, and PLC Protocol option must be used when the OIT is configured for the
first time (default). This selection will send the primary OIT operational software, the PLC
protocol driver, and the project data configuration file to the OIT. The Project and PLC Protocol
option should be used when a previously configured OIT is being configured to attach to a
different PLC. The Project Only option should be used most often, after the OIT has been initially
configured and the PLC protocol has already been selected. This option sends the project data
configuration file only and does not send the primary OIT operational software or the PLC
protocol driver. The project data configuration file is everything the system programmer has
created for the OIT using the MAPware 100 software. (For example, messages, function key
configuration, PLC communications parameters, etc.) The Project Only option dramatically
reduces the download time of the OIT. The MAPware 100 software will check to see if the
primary OIT operational software and the PLC protocol driver in the OIT match what is currently
used in the project and give a warning message if there is a mismatch.
If you select Auto Detect, MAPware 100 will ascertain if the OIT is connected to the
computer correctly and which serial port is attached to the OIT. To use this feature, connect
the OIT to the PC and place the OIT in upload/download mode. MAPware 100 will then
search the PC’s serial communications ports. If an OIT was detected, the serial port will be
set on the Communication Options screen (and saved and restored each time you use
MAPware 100) and the OIT will be reset.
Note: If the Read Protect switch is set then the MAPware will be unable to read from the OIT.
Use caution when using this switch. Note that it is project related and if you set this
switch for the current project, a new project will not have this switch set.
Read from OIT
The Read from OIT button is the shortcut for the Transfer/Read from OIT menu item. The
Read from OIT button allows you to read a project stored in the OIT (refer to the
Communications Options screen). To use this feature, make sure that the OIT is connected to
the PC, is powered up, and that the OIT is in upload/download mode. Select either Transfer
Read from OIT (F11) or the Read from OIT button.
Once selected, the following screen appears:
