Overview
The following communications processors are available for
connecting to the programming device or PC:
•
CPs with an internal microprocessor:
- CP 1616 (PCI)
- CP 1604 (PCI-104)
- CP 1613 A2 (PCI)
- CP 1623 (PCIe)
- CP 1628 (PCIe)
Data throughput of Industrial Ethernet
Comparisons between Layer-2 Ethernet cards and
CP 1613 A2/CP 1623/CP 1628 show the respective communi-
cations throughput.
This throughput varies between 0 and the maximum
throughput for Layer-2 Ethernet cards with the corresponding
software packages.
When the CP 1613 A2/CP 1623/CP 1628 is used with software
packages, the communications performance remains constantly
at a high level and ensures fast response times without any
variations.
