Digital Output and Digital Input FET Modules Each DI can be set in the Application Programmer I/O link table to trigger recording of time tagged events upon any input change of state. The time tagged events are recorded in the CPU memory and can be retrieved for various purposes. Each input can be configured to KLV or to a PDV (0, 1) in the Application Programmer I/O link table. This value is shown to the user application program in the event of DI module failure. Also, the predefined value can be used during normal operation to force a value that masks the actual input value. In this case the user application program will get the PDV instead of the actual input value. Each output can be configured to "Keep Last Value" KLV or to a "Predefined Value" PDV (0, 1). This value is executed when the user application program stops or when the module has no communication with the CPU module. Also, the predefined value can be used during normal operation to force a value on the output by ignoring the user application program value. The DO/DI FET module features which can be configured are listed in the table below. Some parameters are per module and some are per input.

Digital Output and Digital Input FET Modules
Each DI can be set in the Application Programmer I/O link table to trigger recording of
time tagged events upon any input change of state. The time tagged events are recorded
in the CPU memory and can be retrieved for various purposes.
Each input can be configured to KLV or to a PDV (0, 1) in the Application Programmer
I/O link table. This value is shown to the user application program in the event of DI
module failure. Also, the predefined value can be used during normal operation to force a
value that masks the actual input value. In this case the user application program will get
the PDV instead of the actual input value.
Each output can be configured to “Keep Last Value” KLV or to a “Predefined Value”
PDV (0, 1). This value is executed when the user application program stops or when the
module has no communication with the CPU module.
Also, the predefined value can be used during normal operation to force a value on the
output by ignoring the user application program value.
The DO/DI FET module features which can be configured are listed in the table below.
