C: First control word
The six control words C to C+5 specify the number of bytes of command data
and response data, the destination, and other settings shown in the following
table.
Word Bits 00 to 07
C
Bytes of command data: 0002 to maximum allowed
C+1
Bytes of response data: 0000 to maximum allowed
C+2 Destination network address:
4, 6
00 to 7F
C+3 Destination unit address:
5, 7, 9
00 to FE
C+4 No. of retries: 00 to 0F (0 to 15)
C+5 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 number of bytes of command data in C is 0002 to the maximum data
length in hexadecimal. For example, the number of bytes would be 0002
to 07C6 hex (2 to 1,990 bytes) for Controller Link systems. The number
of bytes for the local CPU Unit is 07C6 hex (1,990 bytes). The number of
bytes of command data depends on the network.
