● The latch counter function operates regardless of the ON/OFF status of CH1 Count enable command (Y06).
● IN addition to the latch counter function introduced in this section, there is the latch counter/preset/replace function.
( Page 143, Section 4.11)
● When the latch counter function by the latch counter input terminal is performed, operation response time follows "Latch
counter input response time setting" in the switch setting.
Since CH1 Latch count value (latch counter input terminal) (Un\G1054, Un\G1055) is updated synchronizing with the
internal control cycle, a delay occurs until the latched value is stored (the maximum delay: 2ms + set time of "Latch
counter input response time setting" minutes).
● When the latch counter function (counter function selection) is performed by the function input terminal (FUNC1),
operation response time follows "Function input response time setting" in the switch setting.
Since CH1 Latch count value (Un\G1052, Un\G1053) is updated synchronizing with the internal control cycle, a delay
occurs until the latched value is stored (the maximum delay: 2ms + set time of "Function input response time setting"
minutes).
● The latch counter function (counter function selection) cannot be performed while CH1 Selected counter function start
command (Y07) or the function input terminal (FUNC1) is on even if the other one of them is turned on.
● When reading out CH1 Latch count value (latch counter input terminal) (Un\G1054, Un\G1055) through a device that
auto refresh is to be performed, CH1 Latch count value update flag (latch counter input terminal) (Un\G1075) and CH1
Latch count value update flag reset command (latch counter input terminal) (Un\G1023) cannot be used. (If CH1 Latch
count value update flag (latch counter input terminal) (Un\G1075) is Updated (1
H
) after the auto refresh, the value before
the update is read out.)
● When reading out CH1 Latch count value (Un\G1052, Un\G1053) through a device that auto refresh is to be performed,
CH1 Latch count value update flag (Un\G1074) and CH1 Latch count value update flag reset command (Un\G1022)
cannot be used. (If CH1 Latch count value update flag (Un\G1074) is Updated (1
H
) after the auto refresh, the value
before the update is read out.
