CM CANopen Module for SIMATIC S7-1200
Doc.Rev. 1.00
NMT Start-up, 1F80h
This object configures the startup behavior of the device, and how it will manage the slaves. If the mod-
ule is set up as an NMT master in TIA Portal hardware configuration, the module will enable the master
functionality by forcing bit 0 and bit 2 in this object to TRUE. If there is an attempt to set bit 0 and bit
2 to different values from the CANopen bus, an error response is received.
Bit No. Value Description Notes
0 0 NMT master functionality is disabled. Ignore the rest of the
object except bit 1 and 3. Ignore the entries of object 1F81h.
1 NMT master functionality is enabled. The device is master
1 0 Start only explicitly assigned slaves (if bit 3 = 0)
1 After boot-up, perform the service NMT Start Remote Node
All Nodes (if bit 3 = 0)
2 0 Automatically enter Operational state Not supported
1 Do not enter Operational state automatically. The SIMATIC
S7-1200 PLC will decide when to enter Operational state
3 0 The NMT master shall start the slaves
1 The NMT master is not allowed to send NMT Start Remote
Node command. The application will start the slaves
4 0 If a mandatory slave generates an Error Control Event, treat
the slave individually
If bit 6 = 1, ignore bit 4
1 If a mandatory slave generates an Error Control Event, per-
form NMT Reset All Nodes, see bit 6 and object 1F81h, bit 3.
5 - Not implemented
6 0 If a mandatory slave generates an Error Control Event, treat
the slave according to bit 4
1 If a mandatory slave generates an Error Control Event, send
NMT Stop All Nodes (including self). Ignore bit 4
7 - 31 - Reserved (0)
