The pins of a symbol represent the electrical connection points of a symbol. Electrical connections are then only recognised as such when the connection line is connected to a pin exactly. Up to 2 parameters can be assigned to each of these pins – the pin number and pin name.
Important
However, the pins cannot be placed until the symbol body has been created.
Some special features
The connection is important for the list generator (terminal diagram and connection list). For the list generator, the pin number has a higher priority than the pin name. A pin name can be made invisible by using an ! as the first character. An invisible name is visible in the symbol editor in any case but a pin number is always visible.
Give each pin a pin number or a pin name. The list generator cannot process a pin without a pin number or a pin name and it will not appear on the terminal diagram.
