Description
7860
Via CANOPEN_SETSTATE, parameters of the master, a slave device or a node in the network can be
set.
The treatment of the NMT state of master, node or device is carried out in the CAN stack or via the
commands of the FB
CANOPEN_NMTSERVICES
(
→ p.
97 ). At the same time admissibility checks are
carried out. For reasons of consistency no inputs are provided for this purpose.

Parameters of the inputs
7861
Parameter Data type Description
EXECUTE BOOL := FALSE FALSE  TRUE (edge):
execute function element once
otherwise: function element is not active
A function element already started is processed.
CHANNEL BYTE CAN interface (1...n) depending on the device
NODE BYTE Node ID = ID of the node (0...127)
Device as CANopen master:
Value = 0:
The changes only refer to the device itself.
Value not 0:
Node ID of a node in the network the parameters of which are to be
changed. The established settings are only adopted for this node (not
for the device).
Device as CANopen slave:
In slave mode, the node ID of the slave can be set via this input.
Value = 0:
no action
Value not 0:
The function block adopts this value as the new node ID of the device.
GlobalStart
(optional use of the parameter) BOOL := TRUE Requirement: FB must be called immediately after starting the IEC
program. This setting overwrites the setting of the configuration.
TRUE:
Start all participants simultaneously
FALSE: Start all participants one after the other
CfgTimeout
(optional use of the parameter)
TIME := T#0ms set configuration timeout for a node:
Value = 0:
no action – retain configuration data
Value not 0:
overwrite data from the configuration with the new value
