Process line HMI system
View Patent ↗An HMI renders on an HMI screen a process line which includes: a movable looper group part obtained by grouping at least one movable roll part and a plurality of line parts connected to the movable roll part; and a plurality of fixed roll parts connected to the movable looper group part. The HMI continuously obtains a process line length from an output signal of a monitoring target device. The HMI calculates a looper movement amount by dividing a difference between a process line total length and the process line length by the number of parts in the plurality of line parts which are shared by the movable looper group part with the plurality of fixed roll parts. The HMI changes a relative position between the plurality of fixed roll parts and the movable looper group part on the HMI screen according to the looper movement amount.

continuously obtain a process line current length from the monitoring target device;
calculate a looper movement amount by dividing a difference between a process line total length and the process line current length by a number of parts in the plurality of line parts, wherein the plurality of line parts are shared by the movable looper group part with the plurality of fixed roll parts; and
change a relative position between the plurality of fixed roll parts and the movable looper group part on the HMI screen according to the looper movement amount.
