Troubleshooting 7-3
73 Device’s identity information does not
match electronic key in scanlist table
entry (node number alternately
flashes). Verify that the correct device is at this
node number. Make sure that the device
at the flashing node address matches
the desired electronic key (vendor,
product code, product type).
74 Data overrun on port detected. Modify your configuration and check for
invalid data. Check network
communication traffic.
75 No scanlist is active in the module. Enter a scanlist.
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 scanlist entry (node number
alternately flashes). Reconfigure your module for the correct
transmit and receive data size.
78 Slave device in scanlist table does not
exist (node number alternately
flashes). Add the device to the network, or delete
the scanlist 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. Verify baud rate.
80 Module is in IDLE mode. Put PLC-5 in RUN mode. Enable RUN bit
in module command register.
81 Module is in FAULT mode. Check ladder program for cause of fault
bits.
82 Error detected in sequence of
fragmented I/O messages from device
(node number alternately flashes). Check scanlist 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 (node number
alternately flashes). Check accuracy of scanlist table entry.
Check slave device configuration. Slave
device may be in another master’s
scanlist. Reboot slave device.
84 Module is initializing the DeviceNet
channel. None. This code clears itself once
module attempts to initialize all slave
devices on the channel.
85 Data size larger than 255 bytes (node
number alternately flashes). Configure the device for a smaller data
size.
86 Device is producing zero length data
(idle state) while channel is in Run
Mode. Check device configuration and slave
node status.
88 This is not an error. At power-up and
reset, the module displays all 14
segments of the node address and
status display LEDs. None.
90 User has disabled communication port. Reconfigure your module. Check the
disable bit in the Module Command
Register.
