CH1 - CH3 Status Indicators
Status Cause Corrective Action
Off The 1769-SM1 module is not
powered.
The channel is not connected
to a DPI or SCANport-
supported drive.
The port ID is not valid.
• Apply power to the 1769-SM1 module.
• Apply power to the DPI or
SCANport-supported drive.
• Connect the 1769-SM1 module to the
drive using a 1202-C* communications
cable.
Flashing
Red An error occurred during the
initialization/logon sequence.
A ping timeout error occurred.
A status timeout error
occurred.
The channel was enabled to
pass I/O to the drive, and then
was disabled.
• Verify that the 1202-C* communications
cable is securely connected.
• Cycle power to the drive.
• Avoid disabling a channel after enabling
it to pass I/O.
Solid Red The drive has refused an I/O
connection from the
1769-SM1 module.
Another peripheral is using
the same DPI/SCANport port
as the 1769-SM1 module.
The DPI/SCANport port
number has changed or is not
valid.
A CAN bus-off error occurred.
Important: Cycle power to the drive after
making any of the following corrections:
• Verify that all 1202-C* communications
cables are securely connected and not
damaged. Replace cables if necessary.
• Verify that the drive supports Datalinks.
• Configure the 1769-SM1 module to use
a Datalink that is not already being used
by another peripheral.
Flashing
Green The channel is connected to a
drive, but I/O data is not being
passed between the controller
and drive. No action required. Normal behavior if I/O
is not enabled.
