Setting The Maximum Transmission Unit (For Pcs 7 Only); Enabling/Disabling Time Synchronization; Interfaces And Connections (For Pcs 7 Only); Ethernet Interfaces - Siemens SIMATIC IPC647E Produktinformation

Example:
When using the NVMe SSD as the system volume, a drive combination of a 512 GB NVMe single SSD and a 480 GB SATA RAID
1 volume has data partition DATA_H01 on the system volume and data partition DATA_S02 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 only)

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 Industry PC in a domain (for PCS 7 only) (Page 20).

Interfaces and connections (for PCS 7 only)

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 "X1P1": Terminal bus 1
• Onboard Ethernet interface "X2P1": Reserve
• Onboard Ethernet interface "X3P1": Plant bus 1 (BCE)
Interfaces and connections
SIMATIC IPC647E can be ordered in two versions that differ in regard to the available PCI Express slots on the motherboard.
The following therefore distinguishes between the two types based on the number of available PCI Express slots:
• SIMATIC IPC647E with 2 x PCI and 2 x PCI Express: Referred to as Type 1 in the following
• SIMATIC IPC647E with 4 x PCI Express: Referred to as Type 2 in the following
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.
