DH+ Terminal Messages
Error Number Terminal
Messages Type Meaning Recommended Action
675 or 684 Required network
node(s) not found Comm Status The network is active, but the logic
controller(s) are not located at the
expected nodes. Verify that the logic controller(s)
required by the application are at the
expected node addresses and that
the communication parameters are
set properly.
676 or 685 File access error Comm Status 1. The terminal is trying to access one or
more controller data files that are
unavailable.
2. If the message is flashing, the
terminal is trying to read or write data
files that are unavailable.
1. The data files do not exist on the
controller. Create the data files.
2. The data file is smaller than what is
required. For example, the PanelView
uses N7:10 but only N7:0 is defined in
the controller.
677 or 686 Unstable DH+
network Comm Status Corrupt data packets or intermittent
system configuration was detected
on DH+ network. Verify all controller addressing and
baud rate settings. Check for loose or
reversed wiring.
678 or 687 Duplicate node
detected Comm Status More than one node was assigned
the same address. Verify all device nodes.
679 or 688 No active Node(s)
found on network Comm Status No other DH+ devices can be located
on the network. Verify that PanelView terminal and
logic controller(s) are correctly
connected to the system. Check cable
and wiring.
If error continues, verify that baud
rates on the terminal and controller
are the same. Communication
resumes when the problem is
corrected.
681 or 690 DH+ hardware
failed Comm Status During startup, the terminal detected
a missing, corrupt, or nonfunctional
DH+ card. The terminal will run but
not communicate. Contact technical support and provide
the specific terminal message.
