Delete/Replace an I/O Module in Menta Device Specification

[Product_Support]

Issue

It is only possible to remove the last I/O module in the Options > Device Specification list.  And it cannot be removed until all references to hardware I/O are also removed.  Attempts to delete it prior to this will result in:

"The I/O Modules cannot be removed because it is bound to the following blocks:"

If it is the second I/O module of 8 that needs to be changed to a different type, this describes the most efficient way to remove I/O references and put them back.

Environment

Menta

Cause

This warning is a precaution against leaving stranded hardware I/O points if the modules they are associated with are deleted.

Resolution

1. In Menta, go to Options > I/O Configuration Table
2. Click the "Bound to" column header twice to sort by bindings with hardware I/O listed first
3. In this example, remove I/O Module #8.
   1. Find all references to "M8-"
   2. Double click each output. Change the Bind to option to Not connected
   3. Double click each input. Change the Bind to option to Network Variable.  Leave the Network Address blank.
4. Repeat these steps for the I.O module that will be replaced as well as any higher in the list.
5. Go to Options > Device Specification
6. Remove all I/O Modules down to the one needing to be replaced.  Add them back in in the desired configuration.
7. Go back to Options > I/O Configuration Table
8. Click the "Bound to" column header once to sort by bindings with Network Variables listed first
9. Double click each converted input and output and switch them all back to Physical Input, Linear Analog Input, Non-linear Analog Input, or Physical Output, where appropriate.
10. The physical I/O bindings are recalled when the point is changed back to physical I/O.
    Note:  The sensor configurations (0..10V, 2..10V, etc) will need to be set up again.
