■Buffer memory address
The following shows the buffer memory address of this area.
Buffer memory address name
CH Pulse measurement section setting
CH1 Pulse under-measurement flag
• The value indicating whether the pulse is being measured in the pulse measurement function is stored in this area.
• When the pulse is being measured, 1H is stored. When the pulse is not being measured, 0H is stored.
■Buffer memory address
The following shows the buffer memory address of this area.
Buffer memory address name
CH Pulse under-measurement flag
CH1 Measured pulse value update flag
• The update status of CH1 Measured pulse value (Un\G516 to Un\G517) is stored. When the buffer memory areas are
updated, 1H is stored. When the buffer memory areas are not updated, 0H is stored.
• The buffer memory areas shown above are updated without resetting this area. To check the update status once again,
reset this area by the following resetting method.
■Resetting method
Write 0H in this area using a program and reset this area.
When this area is used as an interlock, consider the scan time. Depending on the program used, immediately
after 0H is written by a program, either of the buffer memory areas shown above may be updated, and 1H
may be stored in this area.
■Buffer memory address
The following shows the buffer memory address of this area.
Buffer memory address name
CH Measured pulse value update flag
CH1 Measured pulse value
• The measured value of the ON width or OFF width of the pulse input to the function start input terminal is stored.
• The measurement range is between 2000 and 2147483647 (in increments of 0.1s).
■Buffer memory address
The following shows the buffer memory address of this area.
Buffer memory address name
CH Measured pulse value
CH1 Synchronization measured pulse value
• The measured pulse value is latched by synchronizing with the rise of the synchronization signal during the execution of the
synchronization control function (during the inter-module synchronization control).
• In this area, the measured pulse value is latched only in the pulse measurement mode.
• The range of the stored value is between 2000 and 2147483647 (in increments of 0.1s).
