Ethernet; Ethercat - Pilz PMCprimo C2 Operating Manual

Function description
5.1.5.4

Ethernet

The Gigabit Ethernet interface (X43) connects the PMCprimo C2 to a programming device
for configuration, programming and commissioning. The interface can also be used to con-
nect a visualisation device.
The Gigabit Ethernet interface is compatible with 1000Base-T (Standard Gigabit Ethernet).
Data exchange is possible via Modbus/TCP.
5.1.5.5

EtherCAT

EtherCAT uses the Ethernet Standard (IEEE 802.3) without modifications.
The PMCprimo C2 does not require a setting (CD command) to use the EtherCAT master
as a drive bus.
To do this, however, a CODESYS V3 project must be active (Boot project), where all the
EtherCAT devices are configured.
Before the CODESYS project starts, all the devices must be operational so that they are
detected by the EtherCAT master.
The address assignment of the network subscribers is performed automatically in the se-
quence of the physical arrangement. The sequence of the inserted devices in the device
tree must match the physical arrangement.
Please note the following during operation:
} The device sequence may no longer be modified.
}
It is not permitted to add or remove devices.
The PMCprimo C2 is an EtherCAT master, which is the only subscriber in the segment that
can actively send an EtherCAT frame; all the other subscribers only forward the frames.
This prevents unforeseeable delays and it guarantees real-time capability.
Bit errors in the transmission are reliably detected in the evaluation of CRC check sums.
Rare interferences can be detected and localised with EtherCAT even if the interference
does not influence the functionality of the machine.
