Resetting default values
If you press the Service Pin for seven seconds during the first minute
following a restart, the parameters of the module will automatically be
reset to the factory default settings. A restart occurs following power on.
The green LED on the front will light continuously during activation
(about 7 seconds) and when the reset is completed, it will flash rapidly
(off-line indication).
The parameters of the I/O module are now reset:
• Domain table index 0: ID len = 1, ID = 11
hex

and Clone Domain = 0 (internal parameter making the unit silent,
until its correct address has been set by the system).
• Domain table index 1: Unused.
• Address table index 0: Domain = 0, Node = 0, Rpt Tmr = 16,
Retries = 0, Rcv Tmr = 128, Tx Tmr = 16, Subnet = 0.
