When the address (operand) is touched in the ladder area, up to 71 characters of an I/O
comment will be displayed in the I/O Comment Display Area for the NS15, up to 43 will be
displayed for the NS12, or up to 23 will be displayed for the NS10/8.
If errors (non-fatal or fatal) occur in the connected PLC (CPU Unit), one error name will

first priority.
