YTerm Software Manual
Baud Rate: Select the baud rate that has been set by either DIP switches or
jumpers on the SMC, depending on the controller. For all
controllers, the default baud rate is 19200.
Port: Select the port which corresponds to the location on the computer
where the serial cable has been connected. If a LEGEND–MC or
SMC–4000 controller is used, Ethernet is a communication option.
If Ethernet is selected, the controller’s IP address must be entered.
The window will change display to allow entry of this information
as shown in Figure 7. Note: The local IP address setting is shown
on the screen. If the number is all zeros or something like 127.0.0.1,
this means that the PC’s Ethernet settings are not properly set (in
Network, TCP/IP settings). Also note that if the cable is properly
connected, both the PC’s Ethernet status LED and the one on the
controller will show a valid connection (Typically via a green LED
next to the Ethernet Port). The LEDs should be ON even before the
actual software connection is established.
About YTerm: Click to view the “About YTerm” window, including
version information. System information can be gathered from this
window by pressing the system information button. This
information may be helpful to Yaskawa software development
should incompatibility issue arise.
Enable Hardware Handshaking: To enable hardware handshaking, check
the check box. This is the recommended method for serial
communication. The default setting is “enabled”.
Default Port: The check box that refers to the default port will send the CF
command to the controller after connection. This will cause the
controller to redirect unsolicited information to the port that YTerm
has just opened. This will allow messages from the controller to be
viewed in the terminal window.
Force Connection to Last Handle: If checked, YTerm queries the
controller using _IA3 to determine what handle it is on. If it is not
on the “P” for LEGEND-MC or “H” for SMC4000, then YTerm
sends the HS command to switch handles making the YTerm
connection on either “P” or “H.” This keeps YTerm out of the way
of other devices that the controller might make a connection to
later.
Test Connection: Initiates communication with the controller. Once
communication has been verified, the status panel at the upper right
of the form will turn green, and the controller’s serial number, axis
count, and the firmware version are displayed. Press Continue after
the connection window appears. If connection was not verified, the
status panel will turn yellow.
