Communications Instructions Completion Codes

The status at the completion of the execution of network communications instructions is shown at the words indicated in the following table, as FINS completion codes. During execution of the instructions the status will be 00 or $0000 and this will be reflected at the end of the execution of the network communications instruction.

Words	Functions
Port #0 to #7	A203 to A210 contain the completion codes for the results
Completion Codes	of communications instruction execution for ports #0 to
(A203 to A210)	#7, respectively.

Note For the CS/CJ-series, the completion codes are stored as 2 bytes of data (1 word) upon completion of the execution of SEND(090), RECV(098), and CMND(490). These codes are the same as the re- sponse codes for FINS commands. The first byte of the completion code is placed in bits 08 to 15 and the second byte is placed in bits 00 to 07.

Timing of Reading Responses

Responses should be read on the rising edge (upward differentiation) of the Network Enabled Flag, as shown in the following diagram.
