When setting for set value 1 has been completed, even if an error has occurred, this
flag will turn ON. This flag will turn OFF if bit 00 in word n+2 (Set Value 1 Setting Bit)
turns OFF, or if a command is executed for a bit with a higher priority.
Use bit 13 in word m+2, to check whether the setting was completed under normal or
error status.
When setting for set value 2 has been completed, even if an error has occurred, this
flag will turn ON. This flag will turn OFF if bit 01 in word n+2 (Set Value 2 Setting Bit)
turns OFF, or if a command is executed for a bit with a higher priority.
Use bit 13 in word m+2, to check whether the setting was completed under normal or
error status.
When setting for the count value has been completed, even if an error has occurred,
this flag will turn ON. This flag will turn OFF if bit 02 in word n+2 (Count Value Setting
Bit) turns OFF.
Use bit 13 in word m+2, to check whether the setting was completed under normal or
error status.
This flag shows whether the data stored in words m and m+1 is displayed in BCD or
hexadecimal.
OFF: BCD
ON: Hexadecimal
This flag will turn ON if the data stored in words m and m+1 is set value 1. This flag
will turn OFF if bit 04 in word n+2 (Set Value 1 Reading Bit) turns OFF, or if a
command is executed for a bit with a higher priority.
This flag will turn ON if the data stored in words m and m+1 is set value 2. This flag
will turn OFF if bit 05 in word n+2 (Set Value 2 Reading Bit) turns OFF, or if a
command is executed for a bit with a higher priority.
This flag will turn ON if the data stored in words m and m+1 is the count value. This
flag will turn OFF if bit 06 in word n+2 (Count Value Reading Bit) turns OFF, or if a
command is executed for a bit with a higher priority.
This flag shows the status of count operation.
OFF: Stopped
ON: In operation
This flag shows the status of external output 1.
OFF: Low (OFF)
ON: High (ON)
This flag will always be OFF, when the External Output 1 Enable Bit (word n+2, bit 08)
is OFF.
This flag shows the status of external output 2.
OFF: Low (OFF)
ON: High (ON)
This flag will always be OFF, when the External Output 2 Enable Bit (word n+2, bit 09)
is OFF.
This flag shows the status of encoder input Z.
OFF: Low (OFF)
ON: High (ON)
This flag shows the status of external input.
OFF: Low (OFF)
ON: High (ON)
This flag will turn ON if the count value registers underflow or overflow. Count
operation will stop with the count value at either the lower or upper limit.
To restart count operation, execute counter value setting or resetting. This flag will turn
OFF when counting restarts.
This flag will turn ON if setting for the count value or set values is completed under
error status. This may occur if a value is outside the specified range, or there is an
irregularity in the value format.
This flag will turn OFF when the set values or the count value are set correctly.
