Description
This function counts pulses between -2147483648 and
2147483647, and detects an overflow/underflow when the count
value is outside the range.
This function repeatedly counts pulses between the upper limit
value and lower limit value of the ring counter.
This function compares the count value with the preset comparison
condition, and outputs ON/OFF signals when they match.
This function compares the present count value with the preset
coincidence detection point or a detection area and outputs
ON/OFF signals from the coincidence output terminal when they
match.
This function replaces the count value with any preset numerical
value at the rising edge of Coincidence output 1 and 2.
This function compares the count value with the preset output
status (ON/OFF address) of the coincidence output, and outputs
ON/OFF signals from the extension output module when they
match.
The points for ON/OFF switch can be used up to 16 points.
An extension output module is required for using this function.
This function replaces the count value with any preset numerical
value.
This function can be used with either of the following.
• CH Preset/replace command (RY21, RY39)
• CH Phase Z input terminal (Z1, Z2) of the connector for
external devices
This function acquires the count value and stores it in the remote
register.
This function stores the count value in the remote register.
• This function uses CH Latch counter input terminal (LATCH1,
LATCH2) of the connector for external devices.
This function stores the count value in the remote register.
This function can be used with either of the following.
• CH Selected counter function start command (RY25, RY3D)
• CH Function input terminal (FUNC1, FUNC2) of the connector
for external devices
