REMARKS
The following explains the reception processing on the target station by the send
data length of the SEND instruction.
The allowable send data length ((S1)+9) of the SEND instruction varies depending
on the version. (See the User's Manual (Basic))
Specifying a length value outside the setting range will cause a 4101 error
(OPERATION ERROR) on the local station.

: Performs the processing normally.
: Terminates abnormally and returns an error code to the request source.
1 A C086 error occurs on the local station.
H
On the target station, the corresponding bit in the RECV instruction execution
request area (address: 205) of the buffer memory remains OFF, and no error
occurs.
2 On the local station, although the initial transmission is completed normally, a
C085 error will occur for the second one or later.
H
The target station behaves as follows:
• Upon the initial reception of the SEND instruction message, the corresponding
bit in the RECV instruction execution request area (address: 205) of the buffer
memory turns ON.
• Executing the RECV instruction generates a C1A6
corresponding bit in the RECV instruction execution request area (address:
205) cannot be turned OFF.
• The RECV instruction generates an interrupt, however, the instruction is not be
executed.
3 On the local station, the SEND instruction is completed normally.
On the target station, execution of the RECV instruction generates a 4001
and turns OFF the corresponding bit in the RECV instruction execution request
area (address: 205).
Check the send data length (1 to 480 words) and execute the SEND instruction.
