Keypad Key

The Keypad data type provides single-bit (0-1) input that corresponds to the Operator Panel

keys on the nanoLC. One or TRUE values indicate that a key is being pressed. There are a

total of 15 keys (0-9, four arrow keys, an “OK”) that are available only if the optional Operator

Panel is present on the nanoLC. There is a sixteenth key data item for “Message Input

Ready”.

Output

An Output data item is a single-bit (0 or 1) for use with discrete output points for the I/O sub-

system. A maximum of 32 output points are available.

Register

There are a total of 32 registers. Configurable as Unconfigured, Integer, Date, Time of Day,

Duration (HH:MM:SS or msec). Registers can have an initial value and may be retentive.

Timer/Counter

The Counter data item is configured as a Timer/Counter with a “Counter” subtype. Counters

range in value from 0 to 99,999,999. Timer/Counter data items count upward once per

millisecond. The Timer/Counter value (accumulator) is accessible to flow charts. Timer data

items have a type that determines whether the timer value is seconds and milliseconds or

hours, minutes, and seconds. The range of a Seconds timer is 0.00 to 99,999.999. The

range of an HMS timer is 00:00:00 to 99:59:59. When a Timer/Counter reaches a “Preset”

value, the Timer/Counter stops and sets a “Done” bit.

Duration, Preset, and Retentive Values

Outputs can have a "Duration" measured in seconds (x.xxx) or hours, minutes, and seconds

(HH:MM:SS). Outputs that have a duration can be pulsed, flashed, or latched (see

“Outputs”, below). Outputs without a pre-defined "Duration" are always latched.

Timer/Counters can have a "Preset" that depends on the type (Counter, HH:MM:SS, or

Seconds). A preset specifies the ending (“Done”) value for the timer or counter. When reset,

the Timer/Counter accumulator goes to zero. When the accumulator reaches the “Preset”

value, the Timer/Counter sets the “Done” bit.

Outputs, Flags, Timer/Counters, and Registers can be retentive. The term retentive

indicates that nanoLC writes the value of the data item to flash memory whenever the

Runtime project closes or the nanoLC loses power. Retentive data items have initial values

equal to their previous value before shut-down.

To configure a "Duration" or "Preset", do the following:

For digital Outputs, enter a value in the "Duration” column; or for Timer/Counters, enter

a value in the “Preset” column.
