Functional description
Communication with AS-Interface Double Slave GLK31A
9.1.3 B-slave function
The B-slave is used to transmit various status and control words between AS-Interface
master and MOVIGEAR
®
inverter.
Using serial AS-Interface data transmission (analog profile) allows for writing and read-
ing MOVIMOT
®
parameters and display values.
• According to profile S-7.A.F.5, the AS-Interface master acyclically transmits several
data bytes to the GLK31A option (B-slave).
• The microcontroller of the GLK31A option processes those signals and transmits
them according to the MOVILINK
®
protocol (parameter telegram) via the SBus inter-
face of MOVIMOT
®
.
• The MOVIGEAR
®
inverter transmits the response telegram to the GLK31A option via
SBus interface.
• The GLK31A option converts the response telegram and transmits it to the AS-Inter-
face master via the serial AS-Interface (analog profile).
For communication via SBus interface, the acyclical parameter transmission of the B-
slave has higher priority than the cyclical control word of the A-slave. Due to the cycle
time on the AS-Interface, at least one process data protocol is performed between the
parameter transmissions.
Communication via the B-slave is always performed acyclically. Transmission of
parameters via the internal SBus interface requires a corresponding parameter call of
the AS-Interface master in conjunction with a higher-level controller.
