4.5.3 Application Module Header
The following table defines the layout of the Application Module Header. The non-shaded sections of the table are
common to all application modules for the 5136-DNP-PCI. The shaded areas are either optional or the function is
determined by the application module. See the application module reference guide for details.
Offset Name Data Type Description
0000h ModuleType CHAR[2] "DN" (0444eh) = card OK
"ER" (04552h) = fatal error
0002h WinSize UINT2 Set by loader to indicate host interface window size.
0 = 16K, 1 = 32K, 2 = 64K, 3=128K
0004h CardId UINT2 For host application use
0006h Kernel Id UINT2 Kernel identification.
0x01 = CAN 2.0A kernel
0x02 = CAN 2.0B kernel
0008h Kernel Rev UINT2 Kernel Revision
000ah ModuleId UINT2 Module Id.
000ch ModuleRev UINT2 Module revision.
000eh NetSerial UINT4 DeviceNet serial number.
0012h CardType CHAR[16] Card type. (i.e. "5136-DNP-PCI")
0022h CardSerial CHAR[8] Card Serial number.
002ah IrqControl
1
UINT2 Card interrupt control.
002ch IrqStatusA
1
UINT1 Card interrupt status.
002dh IrqStatusB

UINT2 Main Application Error Code
0030h CanStatus UINT2 CAN status word.
0032h CanTx UINT2 CAN transmit counter. Incremented when messages are
submitted to the CAN controller.
0034h CanAck UINT2 CAN ack error counter. Incremented when a transmit message is
aborted due to lack of acknowledgment from other stations. When
CanAck is incremented, CanTx is decremented to compensate for
messages not actually transmitted.
0036h CanRx
2
UINT2 CAN receive counter. Incremented when messages are received.
Messages that fail the receive filter still increment CanRx.
0038h CanError UINT2 CAN communication error counter. Incremented when a CAN
frame error is detected.
003ah CanLost
2
UINT2 CAN lost messages counter. Incremented when a CAN message
is received before the previous one is queued.
003ch CanOverrun
2
UINT2 CAN receive queue overrun counter. Incremented when a CAN
message is lost due to a full receive queue.
003eh AddCode
1
UINT2 Additional Application Error Code
0040h Message CHAR[60] When ModuleType is "DN", contains the module identification
string. When ModuleType is "ER”, contains the kernel error string.
007ch MajorTickInterval UINT2 Major Tick Interval (equivalent of system timebase)
007eh MinorTickCount UINT2 Number of minor ticks per major tick interval
0080h Application
1
Undefined Application host interface. The format of this area is defined by the
application module.
