Ethernet Communication Protocols
In addition to the safe
ethernet
, HIMatrix supports the following Ethernet communication
protocols:
SNTP
Modbus TCP
Send & Receive TCP
PROFINET IO and PROFIsafe (with F*03 only)
EtherNet/IP (up to CPU OS V7)
Refer to the corresponding communication manual for details on the various protocols.
4.2.5.1
SNTP
The SNTP protocol (simple network time protocol) is used to synchronize the time of the HIMA
resources via Ethernet. The current time can be retrieved via Ethernet in predefined time
intervals from a PC, or a HIMA resource configured as SNTP server.
HIMA resources with COM OS V6 and higher, can be configured and used as SNTP server
and/or as SNTP client. The SNTP server communicates with the SNTP client via the non-safe
UDP protocol on port 123.
For further details on the SNTP protocol, refer to the SILworX communication manual
(HI 801 101 E) or the online help of the programming tool.
4.2.5.2
Modbus TCP
The HIMA-specific designation for the
non
-safety-related Modbus TCP is Modbus Master/Slave
Eth.
The fieldbus protocols Modbus master/slave can communicate with the Modbus TCP via the
Ethernet interfaces of the HIMatrix controllers.
In a standard Modbus communication, the slave address and a CRC checksum are transferred
in addition to the instruction code and data, while in a Modbus TCP, this function is assumed by
the subordinate TCP protocol.
For further details on the Modbus TCP, refer to the SILworX communication manual
(HI 801 101 E) or HIMatrix Modbus master/slave manual (HI 800 003 E).
4.2.5.3
Send & Receive TCP
S&R TCP is a manufacturer-independent,
non
-safety-related protocol for cyclic and acyclic data
exchange and does not use any specific protocols other than TCP/IP.
With S&R TCP, HIMatrix systems are able to support almost every third-party system as well as
PCs with implemented socket interface to TCP/IP (e.g., Winsock.dll).
For further details on the S&R TCP, refer to the SILworX communication manual (HI 801 101 E)
or HIMatrix TCP/SR manual (HI 800 117 E).
4.2.5.4
PROFINET IO and PROFIsafe (with F*03 only)
The non-safety-related protocol PROFINET IO and the safety-related protocol PROFIsafe are
only available for F*03 controllers and must be configured using SILworX. Refer to the SILworX
communication manual (HI 801 101 E) for more information about communication.
4.2.5.5
EtherNet/IP (up to CPU OS V7)
EtherNet/IP communication is only supported in ELOP II Factory. EtherNet/IP is not supported
in SILworX.
EtherNet/IP (Ethernet Industrial Protocol) is an open industrial communication standard for
exchanging process data via Ethernet.
