On page 4-10, replace the text below the subhead, “4.1.4 Reading Input
Relays” with the following text.
Table 4.4 shows the input relays used in the Pulse Input Module.
Input relays are either latched type or state type. A latched type input relay turns on when
its setting condition is true; it stays on until the output relay that is used to turn off the
input relay changes from off to on. A state type input relay is on as long as its setting
condition is true; it is off when its setting condition is false. To clear (turn off) a latched
type input relay, turn off the corresponding output relay and confirm that the input relay
has been actually cleared before turning off the output relay. Turning on the output relay
for only one scan may fail to clear the input relay.
On page 4-12, replace the note to Table 4.5, “Output Relays Used in the
Pulse Input Module” with the following text.
Note: After turning on an output relay, be sure to confirm that the corresponding input relay has actually been cleared before
turning off the output relay. When a counter stops running after its value returns to 0, you can restart the counter by
changing the appropriate output relay Y
35, Y
39, Y
43, or Y
47 from off to on. This resets the
input relay that will be turned on when the ring-up counter maximum value is exceeded.
On page 4-19, replace the text below the subhead, “4.2.7 Reading Input
Relays” with the following text.
Table 4.8 shows the input relays used in the Pulse Input Module. A latched type input
relay turns on when its setting condition is true; it stays on until the output relay that is
used to turn off the input relay changes from off to on. A state type input relay is on as
long as its setting condition is true; it is off when its setting condition is false. To clear (turn
off) a latched type input relay, turn off the corresponding output relay and confirm that the
input relay has been actually cleared before turning off the output relay. Turning on the
output relay for only one scan may fail to clear the input relay.
On page 4-23, replace the note to Table 4.9, “Output Relays Used in the
Pulse Input Module” with the following text.
Note: After turning on an output relay, be sure to confirm that the corresponding input relay has actually been cleared before
turning off the output relay. When a counter stops running after its value returns to 0, you can restart the counter by
changing the appropriate output relay Y
35, Y
39, Y
43, or Y
47 from off to on. This resets the
input relay that will be turned on when the ring-up counter maximum value is exceeded.
