TAC Xenta 400 I/O modules 3 Technical description
Type No. TAC Menta Block type Terminal ref. Override (492)
Analog outputs 8 AO - Analog outputs Y1 -Y8 – / Man-Auto
Restoring to the default values
If you press the Service Pin for seven seconds during the first minute
following a restart, the parameters of the module will be restored to
the factory default values. A restart occurs following power on.
The green LED on the front will light continuously during activation
(about 7 seconds) and when the restore has finished, it will flash
rapidly (off-line indication).
The parameters of the I/O module will now be restored:
• Domain table index 0: ID len = 1, ID = 11
hex
, Subnet = 1, Node = 1
and Clone Domain = 0.
• 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.
• Address table index 1: Unused.
• Non_Group_Receive_Timer = 768 ms.
• Node Mode: Unconfig.
• Network Management Authentication = Off
• Pre-emption Timeout = Forever
• The start values of the analog outputs will be reset.
