S4C008 to S4C015: PARITY OF USER OUTPUT GROUPS
These parameters specify whether the output group instruction is executed with parity check (even
parity).
Parity bits are set as the highest level bits of each output group. For example, if OG#01 is specified
with parity and DOUT OG# (1) 2 is executed, the result will be 00000010 if 2 is binary converted. Since
there will be only one bit (odd) ON at this time, the parity bit (highest level bit) will be set to ON and
10000010 (130) will be output to OG# (1).
As in the case of a variable such as DOUT OG# (1) B003 parity bits are added to the contents of the
variable data. However, if the contents of the variable exceed 127, as in the case of DOUT OG# (1)
128, an alarm will occur. Remains unchanged if no parity check is specified.
