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.
Word Bits 00 to 07
C
Number of words: 0001 to maximum allowed
C+1 Destination network address:
00 to 7F (0 to 127)
C+2
Destination unit address: 00 to FE
C+3 No. of retries: 00 to 0F (0 to 15)
C+4 Response monitoring time: 0001 to FFFF (0.1 to 6553.5 seconds)
(The default setting of 0000 sets a monitoring time of 2 seconds.)
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. Port numbers 1 and 2 indicate serial ports 1 and 2 (physical ports) of the
destination device.
When transferring data to a computer connected via Host Link, specify the
serial port to which the computer is connected. This setting is used in com-
bination with the destination unit address set in bits 0 to 7 of C+2.
