The response (end) codes listed in the following table are returned in the
response frame for Host Link commands. When two or more errors occur, the
end code for the first error will be returned.
Probable cause
No problem exists.
cuted when the PC is in RUN mode.
The command that was sent cannot be exe-
cuted when the PC is in MONITOR mode.
The PC's UM is write-protected.
The program address setting in an read or
write command is above the highest program
address.
The FCS is wrong.
The command format is wrong, or a com-
mand that cannot be divided has been
divided, or the frame length is smaller than
the minimum length for the applicable com-
mand.
The data is outside of the specified range or
too long.
Hexadecimal data has not been specified.
The operand specified in an SV Read or SV
Change command does not exist in the pro-
gram.
The maximum frame length of 132 bytes was
exceeded.
If the frame exceeds 280 bytes, the Reception
Overflow Flag will be turned ON and there will
not be a response.
The read SV exceeded 9,999, or an I/O mem-
ory batch read was executed when items to
read were not registered for compound com-
mand.
The UM is write-protected.
An FCS error occurred in the second or later
frame, or there were two bytes or less of data
in an intermediate or final frame for multiple
writing.
The command format did not match the num-
ber of bytes in the second or later frame.
There was an entry number data error in the
second or later frame, a data length error, or
data was not set in hexadecimal.
The length of the second and later frames
exceeded the maximum of 128 bytes.

Corrective measures
---
Check the relation between the
command and the PC mode.
Turn OFF pin 1 of the CPU Unit's
DIP switch (SW1).
Check the program.
Check the FCS calculation
method. If there was influence
from noise, transfer the command
again.
Check the format and transfer the
command again.
Correct the data and transfer the
command again.
Check search data or the search
starting point.
Check the command and divide it
into multiple frames if necessary.
Register items to read before
attempting batch read.
Turn OFF the write-protection
Correct the command data and
transfer the command again.
