(46)CH Trigger pointer (Un\G1114 to Un\G1121)
The address of buffer memory which stores the data of when a hold trigger was generated can be checked in
CH Logging data (Un\G5000 to Un\G44999) for each channel.
The difference between the address of buffer memory which stores the data of when a hold trigger was executed
and the start address in CH Logging data (Un\G5000 to Un\G44999) is stored.
For details on the logging function, refer to the following.
Logging Function (
When the value of CH2 Trigger pointer (Un\G1115) is 3550
Ex.
When CH Logging hold request (Un\G1008 to Un\G1015) is turned OFF (0), CH Trigger pointer (Un\G1114 to Un\G1121)
is cleared.
(47)CH Logging cycle monitoring value (Un\G1122 to Un\G1145)
These are the areas for storing the actual logging cycle for each channel. The actual logging cycle is calculated
from the update cycle of data to be logged.
When Operating condition setting request (Y9) is turned on then off, the logging cycle is stored in CH Logging
cycle monitoring value (Un\G1122 to Un\G1145) in the corresponding channel where the logging function is
enabled.
For details on the logging function, refer to the following.
