Function
When RECV2(492) is executed, the number of receive words specified in C starting with the first source
word specified in S at the source node (i.e., the remote node) in the source network specified in C are
received at the destination node (i.e., the local node). The data is written starting from the word
specified in D at the local node.
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 RECV(098) instruction are not used for RECV2(492), which uses the
operand I. The communications port completion code (previously stored in A203 to A210) is stored in
I+1.
