If you are experiencing troubles with an internal dial-up modem:
▪ Check to make sure you've applied power to the FB100. Check the
ON/OFF jumper, the wiring connections at CHG+ and CHG-, and
the wiring at the power source.
▪ Check the wiring to the modem (see Chapter 5).
▪ Check the communication port settings in ROCLINK 800. Refer to
ROCLINK 800 Configuration Software User Manual (Part
D301159X012).
▪ Check the modem INIT string as displayed in the communication
port settings in ROCLINK 800. Refer to ROCLINK 800
Configuration Software User Manual (Part D301159X012).
If you are experiencing troubles with a serial communications
connection (LOI, EIA-232, or EIA-485):
▪ Check to make sure you have applied power to the FB100. Check
the ON/OFF jumper, the wiring connections at CHG+ and CHG-,
and the wiring at the power source.
▪ Check the wiring to the termination block or connector (see Chapter
5).
▪ Check the communication port settings in ROCLINK 800. Refer to
ROCLINK 800 Configuration Software User Manual (Part
D301159X012).
If you are experiencing troubles with an optional I/O point (Analog
Input, Analog Output, Discrete Input, Discrete Output, or Pulse Input):
▪ Check (using ROCLINK 800) to see how the channel is configured.
▪ If the configuration looks correct, then simulate an input (within the
range of the input) or force an output to be produced using
ROCLINK 800 software.
▪ If the types of I/O available for configuration do not match the type
of I/O wired to the I/O terminations, check the I/O Setup screen.
Refer to Chapter 4 for wiring schematics and instructions.
▪ If an input channel is in question, you may be able to use one of the
outputs (known to be in working order) to simulate the required
input. Likewise, if an output channel is in question, you may able to
connect it to a working input channel and check the results.
