ON or OFF.(A relay connection was reserved for each function when thenumber of functions was defined. Keep the 0-0 setting for thosefunctions that are not going to use a relay connection. The line isremoved automatically when set up of the function continues).The following displays will depend on the earlier definitions. Thedisplays will show which connections the earlier settings willrequire. The tables are the same as shown earlier.• Digital outputs• Digital inputs• Analog inputsWe set up the controller’s digital input functions by keying in whichmodule and point on this module each one of these has been con-nected to.We furthermore select for each output whether the function is to beactive when the output is in pos.
