If the send parameter data is received with no user parameter data,

the flags byte is set to zero which selects:

• auto configure

• reset outputs to zero on fault

• reset inputs to zero on fault

The reserved bits must be set to zero to prevent undesired firmware

update behavior. This is the default behavior of the module as

defined in the GSD file.

The descriptions in this chapter use the following example FLEX I/O

configuration to explain the information required for each of these

functions:

Auto Configure Format

The Auto Configure format allows you to change modules without

affecting the User Parameter or Check Configuration data. This

format provides no keying from the master on the I/O modules

installed in the FLEX I/O system. The installed module at power-up

is taken as the key.

If you change a module while it is being controlled by a master, a

minor recoverable fault will occur. To recover from this fault, you

must replace the module with an identical module type.
