Programming via easy-NET
(Routing)
91
Routing offers an advantage which makes it possible to access all
routing capable PLCs on the easy-NET bus from any PLC which is
connected with the programming device. This makes it possible to
operate remotely configured controllers easily.
However, the data transfer rate with routing connections is
considerably slower than with direct connections (serial or TCP/IP).
This will result in slower refresh times for visualisation elements
(variables) or slower download speeds.
The following requirements must be fulfilled in order to use
routing:
• Both the routing PLC and the target PLC must support routing.
• Both PLCs must be connected via the bus.
• The PLCs must have the same active bus baud rate.
Routing via EC4-200
The routing options available are listed in figure 111 and
figure 114.
As shown in figure 111, the PC with the EASY-SOFT programming
software can be connected to the EC4-200 if the configuration of
the EC4-200 already contains an ID (see Configuration).
Establish a connection between the PC and the EC4-200 in the
following way:
X In the Communication/Connection menu in EASY-SOFT select
the COMx interface and the baud rate (standard baud rate of
the EC4-200: 38400 Bit/s).
X Click the Online button. The connection between the PC and the
connected PLC is established.
X Under Device select a target PLC with which you wish to
communicate.
You can then carry out the following functions in the operating
fields:
If you have selected an easy800 as the target PLC, you can execute
the following functions in the Program field:
• Program download
• Online modifications.
You can change the following settings.
