Module Parameter “Ignore module” \ of S500 I/O Devices

All S500 I/O devices have the module parameter “Ignore module”. This parameter allows to set whether the I/O device specified in the PLC configuration is considered or not when checking the configuration data.

The parameter setting No (default setting) requires that the device is physically available.

If the parameter is set to Yes, the device must not be connected!

Thus, it is for example possible 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.

Example:

In full installation (type A), a machine shall be controlled with an AC500 with the following hardware configuration: CPU 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: CPU 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.
