Setting The Maximum Transmission Unit; Enabling/Disabling Time Synchronization; Interfaces And Connections - Siemens SIMATIC IPC547J Manual

Example:
When using the SATA SSD as system volume, a drive combination of 1 TB HDD raid 1 volume and a 480 GB SATA SSD has data
partition DATA_S01 on the system volume and DATA_H02 on the data-only volume.
Note
Risk of data loss
Changing the size of system and data partitions can result in problems when restoring the restore images and thus in a loss of
all data on the drives.
Do not change the size of the system and data partitions.

Setting the Maximum Transmission Unit

For PCS 7 operation, the size of the MTU (Maximum Transmission Unit) for IPv4 is set from 1500 bytes to 1494 bytes. This
setting is necessary for use of the "Parallel Redundancy Protocol" (PRP) in connection with IPv4. On the USB stick, you will find
auxiliary programs and a description for adjusting the MTU setting of your system in the folder "Additional_Products\MTU".

Enabling/disabling time synchronization

Time synchronization with an Internet server is enabled in the Control Panel.
When time synchronization is enabled, an entry may be generated in the event display. This entry can be cleared by disabling
time synchronization.
1. Select "Control Panel > Date and Time > Internet time" tab
2. Disable the option "Synchronize with an Internet time server".
3. Confirm your entries.
Before entering the device into a domain, you should enable time synchronization once again. You can find information on
this in the section: Entering a SIMATIC Industrial PC in a domain (Page 19).

Interfaces and connections

Ethernet interfaces
The Ethernet interfaces in the device are preset to DHCP. If you are not running a DHCP server, configure the IP addresses
manually.
For PCS 7, it is recommended to use the Ethernet interfaces as follows:
• Onboard Ethernet interface "LAN 1": Terminal bus 1
• Onboard Ethernet interface "LAN 2": Reserve
• Onboard Ethernet interface "LAN 3": Plant bus 1 (BCE)
Slots for internal expansion cards
Note
Use the module clamp to secure the expansion cards installed at a later time. We recommend securing the cards in direction
of the device front. When installing the clamp, make sure that you do not damage any of the components on the expansion
cards.
The PCIe expansion card should be used as a plant bus as follows:
• CP1623: Slot 4 (already installed in the IE bundle)
• Redundant communication card: Slot 5
Slot for multi-monitor graphics card
You can expand your device with a multi-monitor graphics card. Use the PCI Express slot 1 (PCIe x16) for this.
