I/O Data Formats
Discrete inputs and discrete outputs are stored as bits in bit cache (status table) memory. Analog
input and analog output data are stored as words and are memory resident in a portion of
application RAM memory allocated for that purpose.
Default Conditions for Model 30 Output Modules
At power-up, Model 30 discrete output modules default to outputs off. They will retain this default
condition until the first output scan from the PLC. Analog output modules can be configured with
a jumper located on the module’s removable terminal block to either default to zero or retain their
last state. Also, analog output modules may be powered from an external power source so that,
even though the PLC has no power, the analog output module will continue to operate in its
selected default state.
Diagnostic Data
Diagnostic bits are available in %S memory that will indicate the loss of an I/O module or a
mismatch in I/O configuration. Diagnostic information is not available for individual I/O points.
More information on fault handling can be in Chapter 3, “Fault Explanations and Correction.”
