Configuration Protection

After configuring a Remote Drop, it is important to prevent inadvertent change while the system is in operation. For this reason, Logicmaster 90±70 automatically protects any configuration you download to a Remote I/O Scanner.

A configuration done with a Hand±held Monitor should be protected as described in chapter 6.

Any Hand±held Monitor used with the system while it is operating should be set up to prevent undesirable configuration changes:

To prevent access to restricted HHM configuration options, remove the HHM key.

Caution

If configuration protection is removed from the Remote I/O Scanner and the Hand±held Monitor's Change Block ID option is ENABLED, the HHM's automatic configuration capability can overwrite any existing I/O configuration, including one created using Logicmaster 90±70, or downloaded using a Write Map datagram.

This automatic reconfiguration will also set any module options (see the table above) back to their defaults.
