Setting up an
Enable Contact An Equation Network’s enable contact, when set, activates the Equation Network. If
an enable contact passes current, the Equation Network will be solved. You chan ge
settings for the enable contact in the Enable Editor display.
To select a type for the enable contact, select the symbol of the enable con tact th at
corresponds with your chosen type. An enable contact can be a normally-open
contact, normally-closed contact, horizontal short, or a horizontal open.
To select a register address for the enable contact, in the Enable Contact address
field, type the direct address (in X:Y numeric format) or symbolic address for the
enable contact coil. This field is only available if the enable contact type is a
normally-open or normally closed contact.
Coil Description
Solved OK Solved OK is set when the equation is being solved without errors.
< Coil Result<0 is set when the equation result is less than zero.
= Coil Result=0 is set when the equation result is equal to zero.
> Coil Result>0 is set when the equation result is greater than zero.
Error Coil Error is set when errors have occurred while solving the equation.
While online, if the Error coil receives power, an error message will
appear under the coil describing the error.
Note: If you don’t want to use a particular output coil, leave the address for that coil
blank (or erase one already typed in). That coil will not be included in the Equation
Network.
