You will then be prompted for a coil description which begins at the
blinking cursor. The description field will show the last coil description
entered as the default.
F9 Ć Other Operations
Five other output operations are described below. They are entered
using the F9 key followed by the letter indicated. To enter one of
these outputs, the cursor must be in the top row of the matrix allowed
for a ladder sequence.
1. T Ć OnĆDelay Timer Coil
The OnĆDelay Timer provides a logically true output whenever the
input is true and the preset time interval has elapsed.
Enter the coil name and define it as either local or common. Then
enter the coil description. You will then be prompted for the PN",
PV", and CN".
The PN, or preset name, is the name of the variable that specifies the
delay between the input turning on and the output turning on. You
must define the PN as either local or common.
Next, enter the PV, or preset value. The preset value unit is 1/10th of a
second. For example, a PV of 10 corresponds to a 1.0 second delay.
Legal values range from 1 to 32767.
The CN, or current value name, is the name of the variable that
specifes the current value of the timer. Current names must be
unique. After you enter the CN, define it as either local or common.
The CV, or current value, is not specified at this time. It will be
displayed only when you are online and monitoring the task.
2. O Ć OffĆDelay Timer Coil
The OffĆDelay timer provides a logically false output whenever the
input is false and the preset time interval has elapsed.
Enter the offĆdelay timer coil in the same manner as the onĆdelay
timer coil described in number 1 above. With the OffĆDelay Timer
Coil, the preset value (PV) defines how long the output stays on after
the input turns off.
3. C Ć Counter Coil
The Counter is capable of counting over the range of +/Ć32767.
Enter the coil name and define it as either local or common. Then
enter the coil description. You will then be prompted for the PN",
PV", and CN".
The preset name (PN) is the name of the variable that selects the
value at which the output will turn on. Define the PN as either local or
common.
Next, enter the preset value (PV). Legal values range from Ć32767 to
+32767.
The current value name (CN) is the name of the variable that holds
the current value of the counter. After entering the CN, define it as
either local or common.
The current value (CV) is not specified at this time. It is displayed only
when you are online and monitoring the task.
