Code Description Take this action
0 - 63 Normal operation. The numeric display
indicates the 1771-SDN’s node
address on the DeviceNet network. None.
70 Module failed Duplicate Node Address
check. Change the module channel address to
another available one. The node address
you selected
is already in use on that
channel.
71 Illegal data in scan list table (node
number alternately flashes). Reconfigure the scan list table and
remove any illegal data.
72 Slave device stopped communicating
(node number alternately flashes). Inspect the field devices and verify
connections.
73 Device’s identity information does not
match electronic key in scan list table
entry. Verify that the correct device is at this
node number. Make sure that the device
at the scrolling node address matches
the desired electronic key (vendor,
product code, product type, etc.).
74 Data overrun on port detected. Modify your configuration and check for
invalid data. Check network
communication traffic.
75 No traffic from other modules detected
on the network. Check the network configuration.
(Scanlist may be empty.)
76 No direct network traffic for module
detected. None. The module hears other network
communication.
77 Data size expected by the device does
not match scan list entry. Reconfigure your module for the correct
transmit and receive data sizes.
78 Slave device in scan list table does not
exist. Add the device to the network, or delete
the scan list entry for that device.
79 Module has failed to transmit a
message. Make sure that your module is
connected to a valid network.
Check for disconnected cables.
80 Module is in IDLE mode. Put controller in RUN mode. Enable RUN
bit in module command register.
81 Module is in FAULT mode. Check Module Command Register for
fault bit set.
82 Error detected in sequence of
fragmented I/O messages from device. Check scan list table entry for slave
device to make sure that input and
output data lengths are correct. Check
slave device configuration.
83 Slave device is returning error
responses when module attempts to
communicate with it. Check accuracy of scan list table entry.
Check slave device configuration. Slave
device may be in another master’s scan
list. Reboot slave device.
84 Module is initializing the DeviceNet
network. None. This code clears itself once
module attempts to initialize all slave
devices on the network.
