Function
When SEND2(491) is executed, the specified number of send words starting with the first source word
specified in S at the source node (i.e., the local node) are sent to the destination node (i.e., the remote
node) in the destination network specified in C. The data is written starting from the word specified in D
in the node with the specified destination unit address.
When the transmission starts, the Execution Completed Flag in I is turned OFF. When a response is
returned, the transmission results is shown in the Error Flag in I. The communications response is
written to I+1.
The Communications Port Enabled Flags (A202.00 to A202.07) and Communications Port Error Flags
(A219.00 to A219.07) used for the SEND(090) instruction are not used for SEND2(491), which uses the
operand I. The communications port completion code (previously stored in A203 to A210) is stored in
I+1.
