Network Instructions
Section 3-25
Description
Writes the specified number of words beginning at S from the local CPU Unit
to the write destination beginning at D in the remote CPU Unit with the node
address specified in C.
Note ECHWR(724) sends an explicit message with the Service Code 1E hex (Byte
Data Write).
Flags
The corresponding Explicit Communications Error Flag will be OFF if the
instruction ended normally or ON if an error occurred.
If an error occurred (corresponding flag in A213 ON), the corresponding Com-
munications Port Error Flag can be used to determine whether the explicit
message itself was not sent (corresponding flag in A219 ON) or that the mes-
sage was sent but there was an error in the message (corresponding flag in
A219 OFF).
The corresponding Communications Port Completion Code (A203 to A210)
will be 0000 hex if the instruction ended normally, an explicit message error
code if an explicit messaging error occurred, or a FINS error code if a FINS
error occurred.
For details on the general operation of the explicit message instructions, refer

Port Enabled Flag
A20200 to
A20207
These flags are turned ON to indicate that net-
work instructions, including PMCR(260) may be
executed for the corresponding ports (00 to 07).
A flag is turned OFF when a network instruction
is being executed for the corresponding port and
turned ON again when the instruction is com-
pleted.
Explicit Communica-
tions Error Flag
A21300 to
A21307
These flags are turned ON to indicate that an
error has occurred at the corresponding ports (00
to 07) during execution of explicit message com-
munications.
The flags will be turned ON if the explicit mes-
sage was not sent or the message was sent but
an error response was returned.
The flag status is retained until the next explicit
message instruction is executed. The flag will be
turned OFF when the next instruction is executed
even if an error occurred previously.
