2.4 Details of Counter Functions
For the counter function, the command is determined according to the settings of the counter fixed parameters and out-
put registers, and the status and counter value are stored in input registers.
The following diagram shows the data flow for the counter function.
ΠIn this section, the fixed parameters mean the counter fixed parameters if not otherwise mentioned.
ΠRefer to 1.3 Self-configuration on page 23 to execute self-configuration of the Machine Controller before set-
ting the fixed parameters.
The following describes the details of pulse counting modes, pulse count function, coincidence output and coincidence
interrupt functions, and PI latch function among the counter functions of the LIO-01 or LIO-02 Modules.
