Parameter
Data type
Description
MASTERSTATE
BYTE
Master state = internal state of the master:
0 = 0x00 = master starts up
4 = 0x04 = node configuration running
5 = 0x05 = normal operating state of the master
255 = 0xFF = PLC running as slave
PLCNODEID
BYTE
PLC node ID = node ID of the PLC the program is running on
Value = 0...127 = 0x00...0x7F
PLCBAUDRATE
DWORD
Baudrate of the PLC
PLCVERSION
DWORD
PLC version
CANSTATE
BYTE
Status of the CANopen network
Device operated as master:
Node ID = 0 (device as such):
0 = 0x00 = OK
128 = 0x80 = BUSOFF
Node ID ≠ 0 (node):
0 = 0x00 = OK
1 = 0x01 = guard or heartbeat error on node
128 = 0x80 = BUSOFF
Device operated as slave:
0 = 0x00 = OK
1 = 0x01 = guard or heartbeat error
128 = 0x80 = BUSOFF
NODESTATE
BYTE
Node state = internal node state of a slave seen from the master's
perspective. The input NODEID identifies the node.
-1 = 0xFF = reset after ResetNode
1 = 0x01 = waiting for BOOTUP
2 = 0x02 = after receipt of the BOOTUP message
3 = 0x03 = not yet configured: STOPPED
4 = 0x04 = after configuration with SDOs: PRE-OPERATIONAL
5 = 0x05 = after starting the node: OPERATIONAL
97 = 0x61 = optional node
98 = 0x62 = other device type configured than in 0x1000
99 = 0x63 = node guarding
LASTNODESTATE
BYTE
Last Node State
Node state according to CANopen (with these values the status is also
coded in the corresponding messages with regard to the node).
