Communication
Points cannot be read or commanded from the operator's terminal.
1. Verify that failed points have been properly addressed.
2. Verify the status of the points at the operator's terminal. Verify that points are not
under Operator priority.
No communication over the FLN trunk.
1. Verify the FLN address and communication speed.
2. Verify the FLN trunk is connected to the correct FLN port.
Errors
The error E3600(0x0E10) - Invalid FLN number displays when
adding a point to a TC-16 or TC-24 with FLN support.
 Since the TC-16 and TC-24 support only one FLN port, only 0 or 1 can be entered
for the FLN number.
TC Compact program and database are not down-line loading properly.
 Verify that the TALON View software is at least Revision 3.9.1 (TC-16 and TC-24)
or 3.10 (TC-36).
Troubleshooting the TX-I/O Island Bus
All points on the TX-I/O island bus are failed.
1. Verify all three signals, System Neutral ( ), Communication Data (CD), and
Communication Supply (CS) are connected throughout the entire TX-I/O island
bus.
The 24 Vac LED on the TX-I/O Power Supply is OFF.
1. Check for 24 Vac input.
2. Replace the fuse (4A, 5 × 20 mm, 250V, medium-acting, ceramic fuse).
The I/O module status LED (under the address key) is flashing or the I/O
point status LED is flashing on an open point. All points are operating
normally.
