Transmitting individual parameters via AS-Interface
Communication with AS-Interface Double Slave GLK31A
Deactivating the
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
10096.0
.
"Write request" service:
The slave replies after the system-related transmission times for parameters.
"Write response OK" response telegram:
Once the GLK31A double slave has correctly received the data, it immediately sends
the response 0x51 "Write response OK" to the master. At the same time, the
MOVILINK
®
protocol is sent to the DRC inverter.
The response of the DRC protocol is evaluated with the "Read request" service as fol-
lows to make sure that the [MOVIGEAR® / DRC]
®
inverter has changed parameter
10096.0
.
