Hi,

Concerning a Open Connector function:

The Logo 0BA8 Help online manual says: "Interconnect the output of an unused block (for example, message texts) with this block"

In what cases we will have an unused block in a program?

Why a message text block is considered unused? If this function block is present in a program that is because we need it.

In the other hand, if the interpretation is "interconnect outputs unused of function blocks". In this case, for example, all outuputs unused of Output functions must be connect to a Open conector function. I think that is correct, because I am assuming that a Open Connetor is exclusively a system instruction and not a program instruction.
