Counting function
The debounced signal is counted by a 16 bit counter. Each counter can be set to a
specific count from the local control panel and through the serial interfaces (preload
function). The count (counter reading) can be displayed on the LCD display and output
via the PC and communication interfaces.
Transmission of counts via
the communication
interface
The count is transmitted through the communication interface by triggering an
appropriately configured binary signal input, or by giving a trigger command from the
local control panel, or at cyclic intervals in accordance with the set cycle time. If the
count is transmitted at cyclic intervals, transmission will be synchronized provided that
the ratio (60/set cycle time) is an integer. In all other cases, the count is transmitted at
intervals determined by a free running internal clock.
Resetting the counter
The counter can be reset from the local control panel, through an appropriately
configured binary signal input, or by the general reset function.
