Publication number DSMBCN-UM001B-EN-P February 2003
Name Register Description
CurTuiUniqueID 9314-9315 Keeper CRC. This is the last Table
unique ID (TUI) value (heard from
valid TUI from the network).
CurTuiStatus 9316 TUI Status of last good TUI from
network. If bit 0 is set, it indicates that
channel B is configured; if bit 1 is set,
it indicates that channel A is
configured. Refer to the ControlNet
specification for the remaining bits.
Figure 17 Current Network Parameters
Pending Network Parameters
During an online parameter change, the following registers show the
values of the network parameters that are about to replace the current
network parameters. These values are used internally by the MBCN.
Name Register Description
PndNutLen 9280 Network update time (NUT) in 10 us
increments
PndSMax 9281 Maximum scheduled address. This is
the highest address allowed to
transmit scheduled data.
PndUMax 9282 Maximum unscheduled address. This
is the highest address allowed to
transmit unscheduled data
PndSlotTime 9283 Slot Time. This is the maximum time
to wait for a node to transmit (in 1 us
ticks)
PndBlanking 9284 Minimum gap between frames (in 1.6
us ticks) (always 6)
PndGbStart 9285 Guard Band Start Time (in 10 us ticks)
PndGbCenter 9286 Guard Band Center Time (in 10 us
ticks). This is when the moderator
node sends the moderator packet
PndModulus 9288 Modulus (always 127). This is different
from the scheduling modulus
PndGbPrestart 9289 Guard Band PreStart Time (in 10 us
ticks)
PndTuiUniqueID 9290-9291 Keeper CRC. This is the Table unique
Id (TUI) value after the current network
change is complete
