POSSIBLE CAUSE
POSSIBLE FIX
Continuous blinking yellow status LED…
Watchdog timer has timed out.
In the absence of a client-server relationship
over the network, such as that formed with i2o
(Modbus TCP/IP models only), or between a
Profinet master/client and slave/server, a PLC
or HMI and a server module, the watchdog will
timeout when enabled, but can also timeout if
a client-server relationship has been severed
by a network cable break, or power disruption
at the client.
Cannot Get an i2o Source to Write Digital Outputs on this Module
…
i2o is not supported by this
model.
i2o is only supported on Modbus TCP/IP
models.
Digital Outputs Stopped Working
…
Your digital output shut down
due to contention with a field
input signal.
Contention at the I/O channel triggers a
protection mechanism that causes the output
to turn OFF and you must cycle excitation
OFF/ON to the output to restore output
operation.
12V Analog Excitation Inputs Do Not Allow Output Operation
…
The 12V excitation supply has
been damaged, typically by
connecting 24V to it by
mistake.
Connecting 24V power to the 12V analog
excitation terminals will destroy its TVS and
switching regulator. In this case, connect 24V
excitation (20-28V) to the 24V terminals to
continue operation. If not having 12V analog
excitation is inconvenient, then you may
return your unit to Acromag for repair.
Network Status Field of Device Setup Page Indicates “Failed” Error…
A connection to the unit’s
network card was lost (Device
Setup page Network Status
field indicates “Failed”, its
current outputs go to 0mA).
If your Network status message indicates
“Failed”, try cycling power to the module to
force a re-initialization (The Restore to Out-of-
Box condition or “sanitize” may also recover
unit operation). There are a few scenarios
that can drive this error condition: If you are
changing the configuration of an i2o target
module while i2o messaging to it is active, if
you are using two different software interfaces
to communicate with a unit at the same time
(like the USB configuration software and a
Profinet utility), and if you write to the wrong
holding register address of the unit (directly or
via an i2o message to it).
Unit Does Not Power-
On with 12V Supply…
Your 12V supply is outputting a
voltage below 11.5V.
Most 12V supplies are ±10%. This unit does
not operate below 11.5V. Check your actual
supply voltage under load and make sure it is
at least 11.5V.
