Expanded services of the Com-Server
Subject to error and alteration
20.4 Uploading/downloading configuration data
(Port numbers 8003/read, 8004/write)
These services allow you to read out the configuration data
for the Com-Server stored in the non-volatile memory and
send it to another Com-Server. Especially when installing a
large number of Com-Servers having the same settings this
methjod eliminates having to open a Telnet configuration
connection for each individual unit.
Use of the system password
If a system password has been configured (see section Basic
Configuration of the Com-Server ), this must be null-terminated
(=[ password ] + 0x00) and sent to the Com-Server via the
Control Port within 2s after a connection has been successfully
opened. If the Com-Server does not receive a correct or even
any password within this time, it sends the message PASSWD?
followed by a null byte (0x00) to the client and closes the TCP
connection.
If no system password is configured, the Com-Server expects
or sends the configuration data directly after the TCP
connection has been established.
Reading out the configuration data on port 8003
All the client application needs to do is open a TCP
connection to Port 8003 of the Com-Server. The Com-Server
a c c e p t s i t , a u t o m a t i c a l l y s e n d s i t s 1 0 2 4 - b y t e l o n g
configuration and then closes the connection to the client.
The client application can store this data now in a binary file
and use it for downloading to other Com-Servers.
