Network Instructions Section 3-24
Operand Specifications
Description Sends the explicit message command with service code 10 hex (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. When the response to the explicit message is received, it is stored in the
range of words beginning at D+2.
The setting in bits 12 to 15 of C (0 or 8 hex) determines the byte-order of the
service data stored at S+5.
• Storing Data from the Leftmost Byte
Set bits 12 to 15 of C to 0 hex.
• Storing Data from the Rightmost Byte
Set bits 12 to 15 of C to 8 hex.
