Refer to 6-1 Cycle Time for a table showing I/O refresh times for Group-2
High-density I/O Units.
Flags ER: St or E is not BCD between #0000 and #0009.
St is greater than E.
5-25-10 BIT COUNTER – BCNT(67)

Limitations N must be BCD between 0000 and 6656.
Description When
the execution condition is OFF
, BCNT(67) is not executed. When the exe
-
cution
condition is ON, BCNT(67) counts the total number of bits that are ON in
all words between SB and SB+(N–1) and places the result in D.
Flags ER: N is not BCD, or N is 0; SB and SB+(N–1) are not in the same area.
The resulting count value exceeds 9999.

DM word is
not BCD, or the DM area boundary has been exceeded.)

Description FCS(––)
can be used
to check for errors when transferring data through commu

nications ports.
When the execution condition is OFF, FCS(––) is not executed. When the ex-
ecution
condition is
ON, FCS(––) calculates the frame checksum of the speci

fied
range by exclusively ORing either the contents of words R

to R

+N–1. The frame checksum value
(hexadecimal) is then
converted to ASCII and output to the destination words (D and D+1).
