Introduction
3.5.2 I/O Module
Two I/O modules (AM600-0808ETNE and AM600-1616ETNE) that support EtherCAT remote
communication are provided. The detailed specications are as follows:
1) Basic specications
Item Specications
Power specications 24 VDC (20.4 VDC to 28.8 VDC) (–15% to +20%)
Communication protocol EtherCAT industrial real-time bus protocol
Max. communication baud rate 100 Mbps
Network port/network cable Standard network ports with Cat5e network cables shorter than 100 m
Station number range
Set the DIP switch between 1 and 255 or use the value automatically
assigned by the network bus.
■
The following table lists the performance indicators:
Item Specications
Communication protocol EtherCAT
Service supported CoE (PDO
,
SDO) and FoE
Synchronization mode I/O uses a DC-distributed clock or I/O synchronization.
Physical layer 100BASE-TX
Baud rate 100 Mbit/s (100Base-TX)
Duplex mode Full duplex
Topological structure Linear topological structure
Transmission medium For the network cable
,
see
"Chapter 5 Wiring"
.
Transmission distance Less than 100 M between two nodes
EtherCAT frame length 44 bytes to 1498 bytes
Process data A single frame can contain a maximum of 1486 bytes.
Synchronization jitter of two slaves < 1 μs
Refresh time
1000 digital inputs and outputs: approximately 30 μs; 32 servo axes:
approximately 100 μs
