Member Name
Data Type
Default Display Style
Description
Fault
DINT
Binary
Written either by the module (if a connection exists) or by the controller to 0xFFFF (if the connection cannot be established). See individual bit definitions for module-written status.
DirectData
DINT[3]
Decimal
User-defined direct data
BufferedData
DINT[14]
Decimal
User-defined buffered data
MultiplierProduct
DINT
Decimal
The result of the multiplier block. This value is valid only if a direct transmit word has been configured to use the multiplier block.

Description
Fault
DINT
Binary
Written either by the module (if a connection exists) or by the controller to 0xFFFF (if the connection cannot be established). Refer to individual bit definitions below for module-written status.
ChassisMultiMaster
0
BOOL
Decimal
Multiple chassis CST masters detected.
ChassisCSTFault
1
BOOL
Decimal
This module is a chassis CST slave, but there is no master.
SynchLink
RxFault
2
BOOL
Decimal
The module is configured to receive data, but no signal is present on the receive port.
SynchLink
DataFault
3
BOOL
Decimal
A producer of one or more of the axes, direct words, or buffered words upstream on
SynchLink
is idle or otherwise not producing valid data.
SynchLink
FormatFault
4
BOOL
Decimal
The format received from the upstream node does not match the configured receive format.
SynchLink
MultiMaster
5
BOOL
Decimal
Multiple SL CST masters detected. When this fault is declared, the module stops transmitting, causing
SynchLink
RxFault in all downstream nodes.
SynchLink
CSTFault
6
BOOL
Decimal
The
SynchLink
time master is invalid, meaning either that a
SynchLink
ReceiveFault has been occurring for too long, or that the difference between the received
SynchLink
CST and the module CST is too great. The module will continue to operate using only the chassis master until the CST Drifting time out expires.
SynchLink
CSTUnsynch
7
BOOL
Decimal
This module is the chassis CST master and a
SynchLink
time slave, and it is in the same time zone as the upstream node, but the
SynchLink
master has been invalid for longer than the CST Drifting time out.
SynchLink
MultiplierOverflow
8
BOOL
Decimal
The multiplier block of an upstream node, or of the current node, resulted in an overflow.
RxAxis0Fault
9
BOOL
Decimal
Axis0 data expected from upstream, but not available.
RxAxis1Fault
10
BOOL
Decimal
Axis1 data expected from upstream, but not available.
Axis0NoConsumer
11
BOOL
Decimal
The module is configured to produce Axis0, but no connection has been established to Axis0.
Axis1NoConsumer
12
BOOL
Decimal
The module is configured to produce Axis1, but no connection has been established to Axis1.
TxAxis0Fault
13
BOOL
Decimal
Unable to establish a connection to the first axis, either because there is a connection problem, or because no axis name has been specified.
TxAxis1Fault
14
BOOL
Decimal
Unable to establish a connection to the second axis, either because there is a connection problem, or because no axis name has been specified.
