Monitoring Of Pulse Input Values; Pulse Input Value Change Function - Panasonic FP-XH M8N16PD User Manual

Pulse Input Function

15.1.4 Monitoring of Pulse Input Values

• Pulse input values are saved in the positioning memory (Area no.0/Address H3C0-H3C7).
Pulse input values can be read and monitored via user program.
• Save pulse input values corresponding to the purposes of pulse input (pulsar, and high-
speed counter). (Unit: pulse)
• Accumulated save pulse input values and clear the pulse input values after the pulse input
purposes are changed or the pulse input values are cleared.
 Sample program
An example for monitoring the pulse input value of Axis-1 is given below.

 This symbol is a pulse edge trigger. Please remember to turn 0 to 1
before the change.
 After the change, the unit controller will automatically clear the
corresponding bit.
