Error & Status Messages
A – 3
Message Meaning Type
MESSAGE FILE IS FULL
On–Board Editor
Message
This reminder is displayed when creating a new
message or adding to an existing message. The
internal memory space in the DL40 is filled. The
amount of memory available is displayed as FILE
FREE.. xx. xK on the second line of the screen used
to enter the on–board editor.
MODULE TOO LARGE
Configuration/Status
During Power–Up
Error
The external module contains a DL40 file that is
larger than the DL40’s internal storage space.
MODULE TOO SMALL
Read/Write
External Module
Error
When requesting a write to external memory module,
the internal file size is larger than the size of the
module. Either the file must be reduced by deleting
messages (Chapter 6 or 7) or a larger module must
be installed.
NO INPUT FROM TAPE
Tape Read/Write
Error
The DL40 has timed out waiting for tape input. No
valid characters were received on the tape port.
Verify that READ FROM TAPE was pressed on tape
unit, baud rates are compatible, and cabling is
correct (see Appendix C). If this message is
displayed, the internal DL40 file has already been
erased; a new file must be transferred to the DL40
before messages can be displayed.
NO MODULE INSTALLED
Read/Write
External Module
Error
The user has requested a copy to/from an external
memory module, but the DL40 cannot detect its
presence. If a module is installed, look for bent pins
on the DL4O module connector. Otherwise, the
module is faulted. Contact your local Allen–Bradley
service representative.
NO MODULE PRESENT
Configuration/Status
During Power–Up
Error
The DL40 did not detect an external module during
the power–up sequence.
NO PLC BLOCK XFERS
Run Mode
Error
When you enable the Handshake DIP switch on the
DL40, and the Block Transfer DIP switch is ON, the
DL40 expects periodic Block Transfer Read requests
from the PLC. If no Block Transfer Read requests are
detected for one minute, this error is displayed. The
message will be cleared when a Block Transfer Read
is performed. When status from the DL40 is not
required, the HANDSHAKE dip switch should be set
to OFF to avoid getting this message.
NO PLC COMMUNICATION
Run Mode
Error
The DL40 Remote I/0 port is not actively
communicating with the PLC. Several things can
cause this message to appear (but only when the
DL40 is in the Run Mode).
PLC not powered
Loose or pulled Remote I/0 cable
Reversed Remote I/0 cable wires
Incorrect baud rate
PLC not configured for this rack
NO PLC HANDSHAKE
Run Mode
Error
When the user has enabled the Handshake DIP
switch on the DL40, the Handshake Bit in the PLC
input image must be continually copied over to the
output image. If the DL40 does not see the bit
returned in one minute, this error status will be
displayed. See page 10–28.
ONLY 1 DATE CALLOUT
On–Board Editor
Error
The (Ctrl Y) character (date callout) can only occur
one time in a DL40 message. This error is displayed
if you attempt to enter more than one.
ONLY 1 TIME CALLOUT
On–Board Editor
Error
The (Ctrl T) character (time callout) can only occur
one time in a DL40 message. This error is displayed
if you attempt to enter more than one.
