ECS LAN via COM
If a 4-wire ECS-LAN connection is to be provided via an asynchronous V24 interface, a
new mode is available for the serial interfaces as from V2.48:
LAN-R or LAN-L.
Example:
Two devices shall be interconnected in a TCP/IP network at ECS-LAN level.
Two COM servers are used for this purpose which are linked to one device each per RS
232 interface and are interconnected per Ethernet. COM servers transmit signals in a
transparent manner from the RS 232 interface to the allocated COM server.
As soon as LAN-R or LAN-L has been selected by COM-1 or COM-2 in the setup
menu, the ECS LAN data stream is diverted to this COM interface. The interface
parameters baudrate, parity and handshake are now applicable, instead of the ECS LAN
settings which were previously in use.
Recommendation:
maximum baud rate (115200 Bd), parity OFF, handshake RTS/CTS.
The selected parameters must correspond to the settings of the connected COM
server, however, they may deviate from those of the opposite terminal, if necessary.
Please note
that the now redundant ECS LAN connection should no longer be used.
Please also make sure that the matching resistor for 2-wire parameters configuration is
activated in order to prevent any ECS LAN errors.
Special case: Use of COM and ECS LAN Connection
The ECS LAN connection is not deactivated in the ECS LAN-via-COM operating mode.
Any telegrams to be sent are transmitted both via the associated COM interface and the
ECS LAN interface. Incoming telegrams are processed by both interfaces. Nevertheless,
it is not a star hub configuration as the two interfaces (COM and ECS LAN) cannot “see”
one another.
