WEG CFW11 - Synchronization Modes; Process Data - PDO; Pdos Mapping

Network Operation
6.4 SYNCHRONIZATION MODES
Data update may be performed using two synchronization mechanisms:
SM-Synchronous: data update is based on Sync Managers 2 and 3. When a telegram is received by interface
for data update, at this momment it runs the internal data update routine by the slave.
DC-Synchronous: data update is synchronous, using distributed clock mechanism.

NOTE!
The minimum cycle allowed for CFW11 frequency inverter data updating over the network is 1ms.
6.5 PROCESS DATA - PDO
The process data (cyclic data), used to control and monitor the equipment during operation, are transmitted and
received by the slave using PDOs. There are two types of PDOs:
Receive PDO - RxPDO: receive data from the master, as commands and references. The device provides four
RxPDOs, each with a standard mapping, but only one RxPDO can be enabled at a time.
Transmit PDO - TxPDO: transmit data to the master, as states and process variables. The device provides four
TxPDOs, each with a standard mapping, but only one TxPDO can be enabled at a time.
6.5.1 PDOs Mapping
The mapping defines the content transmitted by each PDO, based on the objects dictionary of the slave. It is possible
to map up to 8 objects for each PDO. This mapping is done using the objects 1600h to 1603h for RxPDOs and 1A00h
to 1A03h for TxPDOs.
