Transmitting individual parameters via AS-Interface
Communication with AS-Interface Double Slave GLK31A
Setting ramp t11
up
Set the ramp time of ramp t11 up (
parameter 8807.0
) to 0.5 s.
"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
8807.0
.
