Eaton The FBT-6 checks for any device not responding to a LAS pass token

Retransmit

The FBT-6 checks for any device not responding to a LAS pass token

and indicates the address (decimal and hexadecimal) of the last device

that failed to respond to the LAS pass token, together with the number

of missed pass tokens since the function was reset. If more than 250

re-transmissions are detected, the display will read “250+”. Pressing

and holding the “SELECT” key for 2 seconds will reset the re-transmit

count for all devices to zero. Pressing the “SELECT” button for less

than 2 seconds displays the number of detected, missed pass tokens

for each device.

Add–Drop

If a new device is added to the network, the Monitor will display

its address and signal level. If a device does not respond to a Pass

Token frame, the device is considered “dropped” by the FBT-6 and

the Monitor will display the address and last known signal level of the

dropped device.

Shield Short

If a short circuit between the + fieldbus wire and the cable shield

is detected, “(+) TO SHIELD SHORT” is displayed. If the short

is between the – wire and the shield, “(–) TO SHIELD SHORT” is

displayed. If a detected shield short goes away the Monitor indicates

an INTERMITTENT SHIELD SHORT to (+) or (-).

may be saved from multiple segments and/or multiple locations on
