1 An individual Module Definition Window cannot be opened for slots set to "EXIOIF," "UNDE-
FINED," or "RESERVED."
2 The MP920 Module has two general-purpose serial ports. The Generic Serial Definitions Window will
be displayed when the MP920 is clicked. The general-purpose serial port parameters are the only
parameters set for the MP920 Module.
3 The SVB-01 Module's MECHATROLINK settings must be made before the Motion Parameters. The
MECHATROLINK Definitions Window can be opened by double-clicking M-LINK in the Details
row of the Module Configuration Definitions Window.
3.5.6 General-purpose Serial Communications Definitions
This section explains the methods for defining general-purpose serial communications sys-
tems.
„ Outline of Generic Serial Communications
The MP920 is equipped as a standard feature with two RS-232 general-purpose serial ports
(port 1 and port 2), enabling data communications with other Machine Controllers and
devices that support RS-232 communications. Ports 1 and 2 can also be used as engineering
ports for the CP-717.
Here, the hardware and software definitions necessary for serial communications are set.
The Machine Controller operates as a master or slave depending on the protocol and accord-
ing to these settings.
• Generic serial communications 01 and 02: If the MP920 is being used as a slave,
responses are sent automatically in answer to queries from the master. If the MP920 is
being used as a master, communications are started using MSG-SND functions within
the DWG or function programs.
