symbolic name which is non-ambiguous in the entire control configuration in

accordance with the IEC 61131 syntax (no blanks and leading digits in the variable

name):

• Symbolic names can be entered by a mouse-click in front of ’AT %... ;’.

Always use the system variables within the PLC program in order to access the

input and output objects or assign values to them.
