Module Parameter Ignore Module

All I/O Modules provide the module parameter “Ignore module”. This parameter determines whether the I/O Module is considered or ignored during the PLC configuration check.

• No: the device must be physically available.
• Yes: the device does not have to be connected and will be omitted during the PLC configuration check.

Thus, it is possible for example to create a project for machines with different hardware configuration and to exclude unnecessary input/output devices from checking by setting the parameter Ignore module to TRUE.

Note

Modules with one byte input and output cannot be detected if they are configured but not connected to the CS31-Bus.

Example

In full installation (type A), a machine shall be controlled with an AC500 with the following hardware configuration: PM581 + 2xDC532 + 1xAX522.

For a variant (type B) of the machine, the second DC532 is not required. This results in the following PLC hardware configuration: PM581 + 1xDC532 + 1xAX522

The PLC configuration is identical for both machines:

In the project for machine type B, the module parameter Ignore module is set to TRUE for the second DC532. Thus, all inputs and outputs have the same addresses.

A further advantage of this parameter is that, for example, not all devices must be available for test purposes.
