PLC Label-it for PL7 will take a PL7 (version 4.3 and higher) application export FEF file and automatically create I/O labels. These labels will either show what physical addresses or what Symbol name is assigned to which input or output on a PLC I/O module. After the software creates the label, the user would print these on their own printer and then insert this label into the sleeve or front of the I/O module. Any module that is available in PL7 can have a label printed. All labels can also be customized and resized to whatever size the user wants. The default size of the labels are designed for Premium series I/O.
