ER:
Indirectly addressed DM word is non-existent. (Content of
DM word is
not BCD, or the DM area boundary has been exceeded.)
EQ:
ON if Cp1 equals Cp2.
LE:
ON if Cp1 is less than Cp2.
GR:
ON if Cp1 is greater than Cp2.

The following example shows how to save the comparison result immediately. If
the content of HR 09 is greater than that of 010, 00200 is turned ON; if the two
contents are equal, 00201 is turned ON; if content of HR 09 is less than that of
010, 00202 is turned ON. In some applications, only one of the three OUTs would
be necessary, making the use of TR 0 unnecessary. With this type of program-
ming, 00200, 00201, and 00202 are changed only when CMP(20) is executed.

The following example uses TIM, CMP(20), and the LE flag (25507) to produce
outputs at particular times in the timer’s countdown. The timer is started by turn-
ing ON 00000. When 00000 is OFF, TIM 010 is reset and the second two
CMP(20)s are not executed (i.e., executed with OFF execution conditions). Out-
put 00200 is produced after 100 seconds; output 00201, after 200 seconds; out-
put 00202, after 300 seconds; and output 00204, after 500 seconds.
