I/O
type & Signal type
I/O types are used to define I/O variables in the typical. It is free to make all different I/O types. It is not necessary to make different I/O types for different logic manufactures (S7, AB, ABB etc). I/O Types like AI [Analog Input] or DI [Digital input] have the same meaning for different manufactures.
It is also possible to create and use I/O signal types. These can be created in this view. Examples for I/O signal types are '4-20 mA' or '0-10 Vdc'. I/O signal types can be added to every I/O type and can later be used on modules and channels to assign the correct I/O. When adding an I/O signal type to an I/O type, that I/O Signal type can be used with that I/O Type. If an I/O signal type is not added to an I/O type the Signal type can not be used with that specific I/O Type.
In the I/O type view the I/O types and I/O signal types are made.
In the products view these I/O types and I/O signal types can then be selected on I/O modules. There are two fields in the products view. The first one, called 'IO signal type', sets the default I/O signal type on a root product and the selected I/O signal type on subproducts or in a project. The second field, called 'Allowed IO signal types', sets the allowed I/O signal types on a root product and is read-only on a subproduct and in a project.
In the I/O unit view these I/O types and I/O signal types can be selected when creating I/O channels.

In this chapter the working of I/O (signal) types in products is explained
Note:
I/O (Signal) types can be chosen on an I/O module that is linked to a product. See add items to a product
Each I/O Module in a product has a function, an I/O Module can be added multiple times, as long as the function is unique.
Further an I/O module can have
One I/O type;
Multiple alowed signal type`s;
One selected I/O signal type, this will be the (default) I/O type used in project.
Example for use
In the I/O type & I/O signal types view both type & I/O signal types are created and asigned.
When an I/O module is assigned to a product, multiple 'Allowed signal types' can be chosen. These are the signal types that where added to the I/O type before.

After selecting some Alowed I/O signal
types an 'Default' I/O Signal type can be selected. (this is optionally)
and can also be dona when the product is placed in project.
