Module Status Word
The Module Status Word (WX1) is used to communicate the overall status of the module. The
module uses the following bit structure:
1
2
3
4
5
6
7
8-15
16
MOD
STATUS
RSVD NET
CFG
RSVD RSVD LS RSVD

Bit 1 - MOD STATUS
-
Module Status
This bit is set to 1 whenever the application
firmware OK and the network server is started.
Note that the 2572 module uses this bit to
indicate fatal error.
Bit 2 –RSVD – Reserved
This bit is reserved for future use.
Bit 3 -NET CFG - Network Configuration
Required
This bit is set by the module application code
to indicate that the network CAMP server has
not been started. The primary use of this bit is
to condition PLC ladder logic to trigger the
Start Network Server command.
When the PLC Start option is selected, this bit
is set to a value of 1 at startup. When the
CAMP network server has successfully
started, this bit is set to a value of 0.
Bit 4 and 5– RSVD - Reserved
These bit positions are reserved for future use.
Bit 6 – LS - Link Status
This bit indicates the status of the Ethernet
Link. It is set to a value of 1 when the Ethernet
port is connected to a functioning Ethernet
hub or switch. Otherwise is set to a value of 0.
Bit 7 – 15 RSVD
-
Reserved
These bit positions are reserved for future use.
Bit 16 HEARTBEAT
-
Heartbeat
The module toggles this bit between 1 and 0
approximately once per second. It is used as
an indication that the module software is
functioning.

Module Control Bits are contained in WY3. Bit 1 is a module reset bit.
When the bit is set and all
four abort triggers are set, the module will perform a hardware reset.
This operation resets the
processor and initiates a complete module restart. It is available for extreme error cases where simply
acknowledging an error or aborting a command does not clear the error.
NOTE:
Once the module has reset, your PLC logic must re-execute any commands used to configure the
module or to start the network server.
