EMSA HS500E Benutzerhandbuch

Another means of communicating with the HS500E is through the standard TCP/IP 
protocol. For this manual, the protocol is referred to as RAW TCP/IP to distinguish it 
from the other industrial protocols.  

In the RAW TCP/IP environment, the HS500E acts as the server and the Host or 
PLC acts as client. 

NOTE: 

The RAW TCP/IP Client (Host or PLC) must connect to the RAW TCP/IP Server 
(HS500E) on port 50200. 

Maximum number of words transferred to/from an RFID tag per read/write cycle: 
100 Words / 200 Bytes 

RAW TCP/IP sessions are established between the Host and the HS500E via TCP/IP 
client software and generally consist of three stages: connection setup, data 
transactions 

and connection termination.  

All connections to the HS500E are initiated by client side software only. If, for 
example, an existing connection terminates unexpectedly, the HS500E will not 
attempt to contact the client software or re-establish a connection. The client is 
responsible for opening, maintaining, and closing all TCP/IP sessions. 

After establishing a successful connection, communications between the client 
software and the HS500E can proceed. When communication is no longer necessary, 
it is the responsibility of the client side application to terminate the connection.
