C: First control word
The five control words C to C+4 specify the number of words to be received,
the source of the transmission, 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 source network address to 00 to specify a source within the local
network. When two or more CPU Bus Units are mounted, the network ad-
dress will be the unit number of the Unit with the lowest unit number.
3.
The following two methods can be used to receive data from a host com-
puter through a serial port with the host link while initiating communications
from the PLC.
