Outline of operation
● Data are sent from the communication port to external devices.
● Data of [n] bytes are sent from the unit / communication port set by the UNITSEL instruction,
starting with the starting address (word address) of the sent data area specified by [S].
● Data to be sent are set by the user program, in the area starting with [S].
● The processing result is stored in the area specified by [D].
■
Processing
● The slot numbers and communication port numbers specified with UNITSEL instruction are
obtained from the system data register (SD).
● This instruction confirms that the general-purpose communication clear to send flag of a
specified communication port is ON and the general-purpose communication sending flag is
OFF.
● When sending is enabled, sent data is transferred to the send buffer of a communication port
and a request to send is executed.
● The case of SCU shows the case that it is used in the following combination.
• COM.0 port equipped in the CPU unit
• Communication cassettes attached to the CPU unit (COM.1 to COM.2 ports)
• Communication cassettes attached to the serial communication unit (COM.1 to COM.4
ports)
● The case of ET-LAN shows the case that it is used in the following combination.
• LAN port equipped in the CPU unit (Applicable models: CPU unit CPS4RE* and CPS3RE*
only)
● As the communication cassette (Ethernet type) has an Ethernet-serial conversion function, the
internal interface operates with similar programs as the case of SCU. The setting method and
programming method are different from those for the CPU with built-in ET-LAN.
