SAFE MODE Switch
The position of the SAFE MODE switch determines whether the FP-20 xx
network module starts up in safe mode. If the software or configuration
information on the module becomes corrupt or cannot be correctly read,
the system may hang after being rebooted or become inaccessible over the
network. All LabVIEW functions are disabled in safe mode, and I/O
module data is not accessible.
If you reboot the FP-20 xx with the SAFE MODE switch in the ON position,
the embedded LabVIEW RT engine does not start; the module starts up in
safe mode. Now you can reconfigure the TCP/IP settings, download new
software using Remote System Explorer, and reboot the FP-20
xx with the
SAFE MODE switch in the OFF position.
RESET Switch
The position of the RESET switch determines whether the IP settings of the
FP-20
xx network module are reset at startup. Reset the TCP/IP settings if
you are moving the module from one subnet to another or if you suspect
that the current TCP/IP settings are bad. Refer to Appendix B,
Resetting the
FP-20xx
, for more information about the procedure for resetting the
FP-20 xx .
User-Configurable DIP Switches 1–5 (for Discrete Input Channels 0–4)
DIP switches 1–5 can be read as discrete input channels 0–4 on the network
module.
Serial Port
The RS-232 serial port can be accessed using the Serial Port VIs.
The RS-232 port is considered port 0 and is a DTE port. Refer to the
FP-20xx Hardware Overview
section of Chapter 1,
Overview of the
FP-20xx Network Module
, for the location of this port. If you are not
running an embedded application, you must target the FP-20 xx in order
to access the serial port. Refer to Chapter 5, LabVIEW RT Programming ,
for more information about targeting the FP-20 xx .
