Number of timeouts on COM1
Number of timeouts on EXP1
Number of timeouts on COM2
These words are counters (reset at starting) which are
incremented at each timeout noticed by the function
for the managing of each serial port protocol.
R/W
These words are counters (reset at starting) which are
incremented at each error (Ex. wrong checksum,
wrong number of received data) noticed by the
function for the managing of each serial port protocol.
R/W
Number of characters present in the rec
serial COM1
Number of characters present in the reception buffer of
serial EXP1
Number of characters present in the reception buffer of
serial COM2
These words contains for each serial, the number of
valid characters present into reception buffer. The use
of these words is significant on free-port mode to
control number of received characters. Any writing on
these words, selects value corresponding to zero,
emptying reception buffer.
R/W
directional counter encoder 3 (high part)
Counts of bidirectional counter encoder 3 (low part)
Counts of bidirectional counter encoder 4 (high part)
Counts of bidirectional counter encoder 4 (low part)
of bidirectional counter encoder 5 (high part)
Counts of bidirectional counter encoder 5 (low part)
These three pairs of words contains value of fast
counters 3,4 and 5. The count is kept also in case of
power failure and it is updated automatically at each
program scanning.
