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.

system configuration was detected

on DH+ network.

Verify all controller addressing and

baud rate settings. Check for loose or

the same address.

rates on the terminal and controller

are the same. Communication

resumes when the problem is

corrected.
