Calculating cross-section with known cable lengths
The minimum cross-section is determined for the known maximum extent of
the easyNET network.

Calculating length with known cable cross-section
The maximum cable length for a known cable cross-section is calculated as
follows:

2.8 Connecting the serial interface
Each easy800 device is provided on the front with a serial interface. The
interface on easy800 standard is factory shipped with a protective cover
fitted. Remove this cover carefully.
The serial interface is used for:
•
connecting the programming cable to the COM serial interface on the PC
and thus as a connection for the easySoft or easySoft-Pro programming
software.
•
the point-to-point communication with MFD-CP4, MFD-CP8 or MFD-
CP10. MFD-CP… must be operated in Terminal mode and thus enable
texts to be output and operator entries. This terminal connection is
supported by easy800 standard from device version 04 and
easy800-SWD from device version 01. Information on MFD-CP4 is
provided in the manual
→
MN05013011Z-EN.
•
the point-to-point communication between an MFD in COM-LINK mode
and an easy800 device for exchanging data (MB, MW, MD). This serial
connection is supported by easy800 standard from device version 04 and
easy800-SWD from device version 01.
•
the communication via the EASY209-SE Ethernet gateway with an
Ethernet network, see manual
“
EASY209-SE Ethernet Gateway“,
MN05013012Z-EN.
•
a memory card on easy800 standard (
“
memory interface“ function).
