Network Instructions
Section 3-25
Applicable Program Areas
Operands
C: First control word
The five control words C to C+4 specify the number of words being transmit-
ted, the destination, and other settings shown in the following table.
Note
1.
The maximum number of words allowed depends on the network being
used. For a Controller Link, the allowed range is 0001 to 03DE (1 to 990
words).
2.
Set the destination network address to 00 to transmit within the local net-
work. When two or more CPU Bus Units are mounted, the network address
will be the unit number of the Unit with the lowest unit number.
3.
The following two methods can be used to send data to the host computer
through a serial port with the host link while initiating communications from
the PLC.
a) Set the destination unit address (bits 00 to 07 of C+2) to the unit ad-
dress of the CPU Unit or Serial Communications Unit/Board and set
the serial port number (bits 08 to 11 of C+1) to 1 for port 1 or 2 for port
2.
