LINK SERV LAYR CODE Description Cause/action
ER03 10H 80H A2H
Slave station detached:
After communication is established,
the value of the successive error
detach detection counter is exceeded,
and communication with the target
slave station is disabled.
When input/output service is performed
with a target slave station, ER03 occurs if
the value of the successive error detach
detection counter is exceeded for a
cause.
If this error occurs frequently, first check
for hardware failures (on communication
boards, communication cables) and
check noise protection.
ER04 10H 70H 61H
No input/output data:
A response frame for input/output
service from a target slave station
contains no data.
A response from the target slave station
includes a protocol-related error.
If this error occurs frequently, ask the
manufacturer of the target slave station
to make a check.
ER05 30H 70H 90H
Abnormal initialization response
command:
A response for initialization service
from a target slave station is
abnormal.
A response frame from a target slave
station is destroyed.
If this error occurs frequently, first check
for hardware failures (on communication
boards, communication cables) and
check noise protection. If this error still
occurs, ask the manufacturer of the
target slave station to make a check.
NOTE
The codes indicated by SERV, LAYR, and CODE
are defined by OPCN-1. When asking the
manufacturer of a target slave station to make a
check, inform the manufacturer of these codes.
CONNECTION MONITOR
CONNECTION MONITOR:
The communication status of each slave station is indicated.
One of the following values is indicated:
"0" : Normal communication
"-" : Disconnected
"E" : Error(from ER01 to ER05 indicated in Table III-2-5)
" " (blank): Slave station not included in MAX SLAVE NO.
NOTE
LINK STATUS and CONNECTION MONITOR
provide real-time communication status indications.
So, for an error that periodically occurs, the
indication blinks.
