5.9 16-Bit Counter Software Setup Options
After
you configure the hardware jumpers, select the associated bits in the
setup words to enable the functions and select the mode. There are two
setup words and two preset words associated with the 16-bit counters. In
the interest of simplicity
, only the parts of these words pertinent to the
16-bit counter are shown. Bits that are in the 1 state set the function; bits
that are 0 reset the function.
The module setup words have two modes: Run and Program. In Program
Mode, the definitions in T
able 5-10 apply; in Run mode, T
able 5-1
1 applies.
During Program mode, the counters are inhibited and the outputs are off.
After setting up the module in Program Mode, set the module to Run Mode
as described in Section 5.10.
T
able 5-9 shows the format of the preset words for Counters 2, 3, 5, and 6.
T
able 5-10 and Table 5-1
1 present the bit definitions for the setup words.
