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:
3
00 to 07
C+3
Destination unit address: 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 maximum number of bytes allowed in the command and response
data depends on the network being used. For a Controller Link, the maxi-
mum setting is 07C6 (1,990 bytes).
2. If the actual number of bytes of response data exceeds the setting in C+1,
the response data will not be stored. If the actual number of bytes of re-
sponse data is less than the setting in C+1, the received data will be stored
