5. It supports the reading emergencies from a slave service.
 Use this service to read an error or an alarm from a slave.
 You can store up to 5 emergencies in a slave.
 You can read emergencies from a slave through a PLC ladder diagram.
6. It supports the SYNC object (synchronous object) service.
7. Several devices can operate synchronously through the synchronous object service.
8. The supported CANopen communication rates are: 20K, 50K, 125K, 250K, 500K, and 1Mbps.
The supported mapping data types are:
Storage
Data type
8-bit
SINT USINT BYTE
16-bit
INT UINT WORD
32-bit DINT UDINT REAL DWORD
64-bit LINT ULINT LREAL LWORD
The CAN port has the following functions when acting as a slave.
 It supports the standard CANopen protocol DS301 V4.02.
 It supports the NMT (network management object) service.
 It supports the NMT state control.
The state of the AS series in the CANopen network is controlled by a master.
 It supports the NMT error control.
The AS Series supports Heartbeat but not Node Guarding.
 It supports the PDO (process data object) service.
 The PDO message transmits the immediate input data and output data.
 It supports up to 8 TxPDO and 8 RxPDO.
 The PDO transmission type: synchronous mode and asynchronous mode
 It supports the emergency service.
If an error or an alarm occurs in the AS series, the master is notified through the emergency service.
