4.1 Establishing communications
MICROMASTER 420 ⇔ STARTER
The following optional components are additionally required in order to establish
communications between STARTER and MICROMASTER 420:
 PC <-> frequency inverter connecting set
 BOP if the USS standard values (refer to Section 6.2.1 "Serial Interface
(USS)") are changed in the MICROMASTER 420 frequency inverter
PC <-> frequency inverter
connecting set
MICROMASTER 420
USS settings, refer to Section 6.2.1 "Serial
Interface (USS)"
STARTER
Menu, Options --> Set PG/PC interface -->
Select "PC COM-Port (USS)" --> Properties --
> Interface "COM1", select a baud rate
NOTE
The USS parameter settings in the
MICROMASTER 420 frequency inverter and
the settings in STARTER must match!
4.2 Establishing communications between the
MICROMASTER 420 ⇔ AOP
 Communications between AOP and MM420 are based on the USS protocol,
analog to STARTER and MM420.
 Contrary to the BOP, the appropriate communication parameters - both for the
MM420 as well as for AOP - should be set if the automatic interface detection
was not carried-out (refer to Table 4-1).
 Using the optional components, the AOP can be connected to the
communication interfaces (refer to Table 4-1).
