For example
The active input level and the type of input (pull-up or pull-down) can be programmed using
the ICON command.
To view the current status of the user definable inputs type IN. All user definable inputs will
be displayed.
Programmable Input Levels
Inputs can be programmed to operate as pull-down (sink) inputs or pull-up (source) inputs.
The pull-up voltage may also be programmed as 5V or 24V. This is achieved by using the
circuit arrangement shown in Figure 7-5, where PROG VOLTS can be programmed to 0V
(pull-down), 5V or 24V (pull-up).
Inputs are configured in 3 banks of 5 inputs, allowing each bank to be programmed
independently. The three banks are:
If you need further information refer to the ICON command.
Verifing Input Wiring
To verify that you have wired the inputs correctly for your application use the IS command.
This command reports the active state of all inputs regardless of the function assigned to
them.
This indicates that no inputs are active.
The voltage level, sink or source operation for the inputs can be configured using the ICON
command. However the IS command will indicate the status of any input regardless of the
input configuration.
