17.3.19 _SBusCommOn

Syntax

_SBusCommOn()

Description

In MOVIDRIVE

®

 B, the command has been replaced by _SBusCommState. However,

due to downward compatibility, it can still be used.

This statement triggers the reception of data and the cyclical transmission of previously
defined data objects. The data objects are initialized using the SBusCommDef function
with the arguments SCD_TRCYCL and SCD_REC. 

Argument

The command does not have an argument.

Example

See section "Compiler – Examples".

17.3.20 _SBusCommState

Syntax

_SBusCommState ( action )

Description

This statement initializes the CAN interface, starts or stops the data reception and the
acyclic transmission of predefined data objects via SBus 1 or SBus 2. The data objects
re initialized via the SBussCommDef function.

Regardless of the value for "action", with MOVITRAC

®

 B, the _SBusCommState com-

mand ( action ) always has the same effect as _SBusCommOn (page 234).

Key points

action   can adopt one of the following values:

INFORMATION

This command only activates SBus 1, not SBus 2

Value

Argument

Meaning

0

SCS_STARTALL

Starts cyclical communication synchronously from 
SBus 1 and SBus 2.

1

SCS_STOPALL

Stop cyclical communication synchronously from SBus 
1 and SBus 2.

2

SCS_START1

Starts cyclical communication from SBus 1.

3

SCS_STOP1

Stops cyclical communication from SBus 1.

4

SCS_START2

Starts cyclical communication from SBus 2.

5

SCS_STOP2

Stops cyclical communication from SBus 2.
