Description
Counts the input pulse from 0 to 99999999. When the input pulse exceeds the count range, an
overflow is detected.
Repeatedly counts the input pulse from 0 to 99999999.
Detects that the accumulating count value exceeds the set value.
Changes the sampling pulse number and the count cycle of the accumulating count value.
Converts the pulse number by multiplying the input pulse number by an arbitrary setting value.
The moving average of the sampling pulse number that is loaded for each count cycle is
processed for the specified number of times to calculate the mean value.
Outputs a warning when the sampling pulse number enters the preset warning output range.
Resets the sampling pulse number, accumulating count value, and input pulse value. These
counters can be reset at an arbitrary timing. The accumulating count value can be preset to
the specified value.
Executes an interrupt program of the CPU module when an interrupt factor such as an error or
warning output is detected.
Stores up to 16 errors and alarms that occurred in the pulse input module in the buffer memory
areas.
Collects the errors and alarms that occurred and the operations executed in the pulse input
module as event information into the CPU module.
Assigns the buffer memory addresses of the pulse input module in the same way as those of
the MELSEC-Q series module. The sequence program that has already been used for the
MELSEC-Q series module can be used.
Allows module replacement without stopping the system. For the procedure of the online
module change, refer to the following.
