PDO communications
(communications using
process data objects)
SDO communications
(communications using
service data objects)
PDO communications is used for const ant data exchang e betw een
a master and slaves. PDO dat a (i.e., I/O data that is mapped to
PDOs) that is allocated in adv ance is input and output each
EtherCAT process data communications cycle (i.e., the task period
of primary periodic task). The NJ/NX-series Machine Automation
Controllers use PDO com mu nications for commands to refresh I /O
data in a fixed control period, including I/O data for slave units a nd
the position control data for ser vomotors. It is accessed from
NJ/NX-series Machine Automation Controllers in the fo llowing
ways.
・With device variables for EtherCAT slave I/O
・With axis variables for a s er vo drive and encoder input slaves to
which an axis is assigned
SDO communications is u sed t o r ead and write specified slave
data from a master when r equired. The NJ/NX-serie s M achine
Automation Controllers use SDO communications fo r com m ands
to read and write data, such as f or paramet er transf ers, at specified
times. The NJ/NX-series Machine A uto mation Cont roll ers can
read/write the specified s l ave data (parameters and error
information, etc.) with t he EC _CoESDORead (Read CoE S DO)
instruction or the EC_CoE SDOWrite (Write C oE SDO) instruction.
slave unit A generic name for a device that performs EtherCAT
communications with a n Et herCAT master. There are various ty pes
of slave units such as servo drives that handle position data and
I/O terminals that handle bit signals.
node address An address to identify a slave unit connected to EtherCAT.
ESI file (EtherCAT slave
information file)
It contains information un i que t o Et herCAT slave units in X M L
format. The ESI file can be loaded into Sysmac Studio, t o allocate
EtherCAT slave process data and make other setti ngs.
