Network Instructions Section 3-25
Operand Specifications
Description Sends the explicit message command (stored in the range of words beginning
at S+2) to the node address specified in S+1, via the Communications Unit
with the FINS unit address specified in bits 00 to 07 of C+1. When the
response to the explicit message is received, it is stored in the range of words
beginning at D+2.
Number of Bytes Settings
The number of bytes of send data in S includes the 10 bytes in S+1 to S+5 as
well as the number of bytes of service data beginning at S+6. (For example, if
there is 1 byte of service data, there are 11 bytes of data all together, so S
must be set to 000B hex.)
The number of bytes of received data in D includes the 4 bytes in D+1 and
D+2 as well as the number of bytes of service data beginning at D+3. (For
example, if there is 1 byte of service data, there are 5 bytes of data all
together and D contains 0005 hex.)
The setting in bits 12 to 15 of C+1 (0 or 8 hex) determines the byte-order of
the service data stored at S+6 and D+3.
