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
