Output to External Output Terminal
The module incorporates four independent external output terminals to allow program-
mable setting of external outputs. Output setting can be made by:
(1) Output selection, and
(2) Interconnections between output and input channels.
(1) Output selection
Comparing the counter values with preset value 1 or 2 allows any output to be se-
lected from among eight latched outputs or status outputs, as well as counter operat-
ing states, “output normally on” and “output normally off.” In the initial state, latched
outputs, after the counter values have been compared with preset value 1, will be
selected.
The latched outputs are turned on when the counter value and preset value 1 or 2
coincide, or when the counter value exceeds a ring up-counter maximum value and is
reset. If a user’s program turns on a related output relay, the latched output will be off
(0). The latched output remains on until it is reset.
A state output will be on when the comparison operation is true, and will be off when
the comparison operation is false.
The counter operating status indication output remains on (1) while the counter is in
operation, and remains off (0) while the counter is not in operation.
An output that is normally on or off remains on or off regardless of the counter operat-
ing status.
(2) Interconnections between input and output channels
Up to four remote output terminals can be set to output comparison results obtained in
a one-input channel. In the initial state, “output is issued to remote output terminals
n
relating to the input terminal n ” has been set. For example, comparison results in input
channel 1 are issued to remote output terminal 1.
Interconnecting between the input and output channels allows comparison results of
counter values in input channel 1 with preset values 1 and 2 to be output to four
remote output terminals. However, note that comparison results in input channels 2
through 4 cannot be issued to the remote output terminals.
