Host Link Errors Section 8-7
The header code will vary according to the command. Some commands
(composite commands) contain a subcode.
Power Interruptions The following responses may be received from the CQM1 if a power interrup-
tion occurs, including momentary interruptions. If any of these responses are
received during or after a power interruption, repeat the command.
Undefined Command Response
@00IC4A*
↵
No Response
If no response is received, abort the last command and resend.

Contents Probable cause Corrective measures
00 Normal completion --- ---
01 Not executable in RUN mode The command that was sent cannot be
executed when the PC is in RUN mode.
Check the relation between the com-
mand and the PC mode.
02 Not executable in MONITOR
mode
The command that was sent cannot be
executed when the PC is in MONITOR
mode.
04 Address over (CPM1/CPM1A/
SRM1 PCs)
The user program area’s highest
address was exceeded.
Check the program.
0B Not executable in PROGRAM
mode
The command that was sent cannot be
executed when the PC is in PROGRAM
mode.
This code is not presently being used.
13 FCS error The FCS is wrong. Either the FCS cal-
culation is mistaken or there is adverse
influence from noise.
Check the FCS calculation method. If
there was influence from noise, transfer
the command again.
14 Format error The command format is wrong. Check the format and transfer the com-
mand again.
15 Entry number data error The areas for reading and writing are
wrong.
Correct the areas and transfer the com-
mand again.
16 Command not supported The specified command does not exist
in the specified address.
(Reading the SV, etc.)
Check the address and instruction.
18 Frame length error The maximum frame length was
exceeded.
Divide the command into multiple
frames.
19 Not executable Items to read not registered for com-
posite command (QQ).
Execute QQ to register items to read
before attempting batch read.
23 User memory write-protected CQM1 PCs: Pin 1 on the CQM1 DIP
switch is ON.
CPM1/CPM1A/SRM1 PCs: The mem-
ory is write-protected in the PC Setup.
CQM1 PCs: Turn OFF pin 1.
CPM1/CPM1A/SRM1 PCs: Change the
setting in the PC Setup (DM 6602).
A3 Aborted due to FCS error in
transmit data
The error was generated while a com-
mand extending over more than one
frame was being executed.
Note: The data up to that point has
already been written to the appropriate
area of the CPU Unit.
Check for corrupted frames, correct if
necessary, and try the transfer again.
A4 Aborted due to format error in
transmit data
A5 Aborted due to entry number
data error in transmit data
A8 Aborted due to frame length
error in transmit data
Other --- Influence from noise was received. Transfer the command again.
