Communication Specifications - Panasonic FP2 ET-LAN Technical Manual

Note1) It is possible to set the unit type to "0SE" by using a programming tool such as FPWIN GR.
Note2) Remote programming and monitoring through the LAN are available using the programming tool
such as FPWIN GR. (Configurator ET does not support the connection via LAN.)
Note3) The usable functions vary according to the version of the used ET-LAN unit.
For the details, refer to <1.4.1 Functions of ET-LAN Unit and Applicable Versions>.
Note4) System connection is used for communication to the programming tool (e.g. FPWIN GR) via LAN.
Note5) 6K words (transmit and receive combined) can be freely allocated to the 8 connections.
Note6) This size includes E-mail, Address Book, and signature data.

Note1) Switching between 100BASE-TX and 10BASE-T is done automatically by auto negotiation
function.
Note2) The standards cite 100 m as the maximum, but noise resistance measures such as attaching a
ferrite core may be necessary in some cases, depending on the usage environment. Also, if the
hub is positioned close to a control board, we recommend using it at a distance of 10 m or less.
Note3) The standards cite 50 m as the maximum, but noise resistance measures such as attaching a
ferrite core may be necessary in some cases, depending on the usage environment. Also, if the
transceiver is positioned close to a control board, we recommend using it at a distance of 5 m or
less.
