5.3.3 Common Communication Configuration Problems
If serial communications do not function, it is often due to one of the
following issues:
 Baud rate mismatch – the baud rate at both ends of the
communication line must match. If communications fail during a
download of a new flash configuration profile (FCP) file, you may
have changed the baud rate of the active communication line, since
baud rate changes occur immediately on FCP download. You can
always re-establish factory default baud rates for communication
ports by powering down the unit, and then setting CPU switch SW2-
3 to OFF and restoring power.
 Incorrect BSAP local address – this address must be an integer from
1 to 127 and must be unique on this particular BSAP communication
line. You set the BSAP local address using the flash configuration
utility. If this ControlWave Micro is a BSAP slave node, and the
range of addresses defined for the BSAP master port end of the
communication line does not encompass the local BSAP address
defined for this ControlWave Micro, BSAP communications will
not function.
 Incorrect EBSAP Group number – if you use expanded BSAP the
EBSAP group number must be correct; if you are not using EBSAP,
the group number must be 0.
If IP communications do not function, it is often due to incorrect IP
addresses or masks. Check to see that the IP address you defined for the
ControlWave Micro is compatible with the range of IP addresses
defined for the communication line on which the unit resides. Also
check that the IP address of the default gateway is correct.
5.4 WINDIAG Diagnostic Utility
WINDIAG is a software-based diagnostic tool you use to test the
performance of I/O modules, CPU memory, communication ports, and
other system components. .
WINDIAG is a PC-based program, so the Micro must be attached to and
communicating with a PC running WINDIAG. Set configuration switch
SW2-8 OFF (closed) on the CPU module to enable the diagnostic
routines.
Establish communication between the Micro (with/without an
application loaded) and the PC with a local or network port under the
following conditions:
