No Output From Module
Verify that the module is marked as present in
the Local I/O setup menu. Verify that the right
number of analog output sub-modules are
present. Verify that the output is assigned to a
real signal from a real Analyzer.
No Digital Output
Verify that the serial output sub-module is
present. Verify that the module itself is
marked as present in the Local I/O module
setup menu. Verify that the communication
settings are correct in the Serial interface
setup menu. Verify that AK or Modbus is se-
lected in this menu. Make sure that you have
a standard serial cable to connect to this
module. Verify that the PC (or whatever de-
vice is used) serial settings match those of the
Local I/O module.
