HI 800 101 HIMatrix Engineering Manual
5.2.5 SNTP
Using the SNTP Protocol (simple network time protocol), the time of the HIMA resources
can be synchronized via Ethernet.
The current time can be polled in defined time intervals via the Ethernet from a HIMA re-
source or a PC, which are configured as an SNTP Server.
HIMA resources having a COM operating system version 6.x and newer can be configured
and can operate as an SNTP server and/or an SNTP Client. The communication of the
SNTP server with the SNTP client runs via the non safety UPD protocol on port 123.
Further informations about the SNTP protocol you will find in the online help of ELOP II Fac-
tory.
5.2.6 Modbus TCP
The HIMA notation for the Modbus TCP protocol is: Modbus Master/Slave Eth.
The field bus protocols Modbus master/slave can communicate with the protocol Modbus
TCP via the Ethernet interfaces of the HIMatrix controllers.
At a standard Modbus communication the slave address and a CRC checksum is transferred
additionally to the instruction code and the data. At Modbus TCP the subordinate TCP proto-
col handles this function.
Further informations about the Modbus TCP protocol you will find in the corresponding man-
ual Modbus master/slave and/or in the online help of ELOP II Factory.
5.2.7 Operating Parameters of the Ethernet Interfaces
Up to COM OS Version 8.32:
All Ethernet ports of the integrated Ethernet switches have the same settings Autoneg /
Autoneg for Speed Mode and Flow-Control Mode. Other settings are not possible or are re-
jected by the controller during loading of configuration.
The Ethernet interfaces 10/100 BaseT of the HIMatrix devices have the following parame-
ters:
Operating parameters
Speed Mode Autoneg
Flow-Control Mode Autoneg
Other devices combined with HIMatrix devices must have the following network settings:
Admissible settings of other devices
Speed Mode Autoneg
Flow-Control Mode Autoneg
or
Speed Mode Autoneg
Flow-Control Mode Half-Duplex
or
Speed Mode 10 Mbit/s or 100 Mbit/s
Flow-Control Mode Half-Duplex
Non-admissible settings of other devices
Speed Mode Autoneg or 10 Mbit/s or 100 Mbit/s
Flow-Control Mode Full-Duplex
From COM OS Version > 8.32 and ELOP II Hardware Management Version 7.56.10:
For each Ethernet port of the integrated Ethernet switch the parameters could be set indi-
vidually (see chapter
5.2.8).
