The BOP, a programming / operator unit (e.g. AOP, PC with DriveMonitor /
STARTER) or a programmable control with communications processor can be
connected via this BOP link. Data transfer between MICROMASTER and the
programming / operator units is realized using the USS protocol via the RS232
interface (point-to-point data coupling). Communications between the BOP and
MICROMASTER uses a optimized interface which takes into consideration the
somewhat limited resources of the BOP. If the BOP is replaced by an USS unit
(PC, AOP), then MICROMASTER automatically identifies the interface of the new
unit. This is also true for the inverse replacement sequence. The BOP link interface
can be adapted to the particular unit using the following parameters (refer to Table
3-13).

Communication modules (CB) such as PROFIBUS, DeviceNet, CANopen and also
programming / operator units (e.g. PCs with the DriveMonitor / STARTER start-up
software and AOP) as well as programmable controls with communication
processor can be connected to the COM link. The plug connector allows the
communication modules to be connected to MICROMASTER. On the other hand,
the programming / operator units must be connected to the MICROMASTER
through terminals 29/30. As for the BOP link, data is transferred between
MICROMASTER and the programming / operator unit using the USS protocol. In
so doing, for the COM link, the USS protocol is transferred via the bus-capable
RS485 interface. Essentially the same as the BOP link, the COM link also
automatically defines if a communications module is replaced with a USS unit (PC,
AOP). The COM link can be adapted to the particular unit using the following
parameters (refer to Table 3-14).
