(Application Functions)
6.12 TIMER_100_FB_M
Outline
This function block generates an output when the condition continues for the specified time.
The initial value and setting value of the timer is multiplied by 100 ms.
1. Format
*1. Refer to "Cautions".
2. Set data
Function and operation explanation
1) When the execution condition of the input argument Coil turns ON, counting the current value starts.
The timer starts counting from "ValueIn
×
100 ms". When it counts up to "Preset
×
100 ms", the output
argument Status turns ON.
The current measurement value is outputted into ValueOut.
2) When the execution condition of the input argument Coil turns OFF, the current value takes on the value
of ValueIn and the output argument Status also turns OFF.
*1. Var_D10 is a global label and is defined as D10.
*2. Var_M10 is a global label and is defined as M10.
Cautions
1) Expression in each language of function block
*1. Set the instance when using the function block.
Describe the instance name when programming the function block.
2) For the function block, the automatic allocation device needs to be set as the timer numbers are allocated
automatically.
