Counting speed (Max.)
The counting speed (Max.) of the pulse input module can be set with "Input filter setting" of the module parameter. This can be
set to one of the following values to match the time that it takes for the input pulse to rise/fall.
• 30kpps
• 10kpps
• 1kpps
• 100pps
• 50pps
• 10pps
• 1pps
• 0.1pps
The counting speed varies depending on the time that it takes for the input pulse to rise/fall. Use the
performance specifications to check the counting speed that can be measured, and then set this value. (

Each of these settings can only be set from the module parameter. They cannot be set from the buffer
memory. However, the current setting details can be checked from the following buffer memory areas.
• 'CH1 Input voltage selection monitor' (Un\G1200) ( Page 94 CH1 Input voltage selection monitor)
• 'CH1 Pulse edge selection monitor' (Un\G1201) ( Page 94 CH1 Pulse edge selection monitor)
• 'CH1 Input filter setting monitor' (Un\G1203) ( Page 95 CH1 Input filter setting monitor)
