The high-speed counter normally provides 16 output bits. If more than 16 are
required, the high-speed counter may be programmed more than once. In
the following program example, the high-speed counter is used twice to pro-
vide 32 output bits.
In this program, each bit in the specified words, HR 0 and HR 1 are turned
ON under the following conditions (where S is the present count value of the
high-speed counter stored as the data of CNT 47):
Where S1 S S2,
Where S3 S S4,
Where S31 S S32, HR 015 is ON.
Where S33 S S34, HR 100 is ON.
Where S63 S S64, HR 115 is ON.
