Transmitting individual parameters via AS-Interface
Communication with AS-Interface Double Slave GLK31A
Deactivating
mechanical control
elements
You have to deactivate the mechanical control elements because the parameters of the
DRC inverter are to be set via AS-Interface. To do so, write the value 65535
dec
=
0xFFFF to parameter
10096.30
.
"Exchange request" service:
When the GLK31A double slave receives the service "Exchange request" 0x1D, it sends
the MOVILINK
®
protocol to the DRC inverter. Once the DRC inverter receives the
MOVILINK
®
response, the GLK31A double slave sends the response "Exchange re-
sponse OK" to the AS-Interface master. This means another "Read request" service of
the AS-Interface master is not required.
The slave replies after the system-related transmission times for parameters.
