 |  S5/S7 to Linux connection using a communication unit (CP). rktcp_server Info:
Uses standard protocol TCP/IP over ethernet.
 Connects to S7 or S5 plc.All CPUs can be accessed.On the Simatic side a device is needed which knows about TCP/IP. 
Normally, a separate communication unit (CP) is needed which is plugged into the rack of the plc. 
There are such units for S7 as well as S5. On S7, also a ProfiNet-CPU can be used.DesignThe package rktcp_server consists of a server process and a client-library written in ANSI-C,
 which you can use to develop applications with access to S5/S7 data blocks.
 Up to 64 client processes can connect to the server at the same time.
 The server process coordinates the concurrent accesses of the clients and is responsible
 for the data transmission to the S5/S7 using TCP/IP.You can connect to several plcs at the same time ! 
  System requirements at Simatic side:

  ( There are a lot of possibilities to link over Ethernet, more informations are 
 here ).  
   Features of rktcp_server: full Client-compatibility with the existing products rk512_server
 and rk511_server. ( you just need to compile/ link with the appropriate Client-Library.) 
 
 Features: 
  
 S7 Communication
  
   Access to DBs 1..16000, DBB 0 .. DBB 65535 (S7-compatible)
   S5-compatible Communication ( TCP/IP with and without RFC1006) 
  
   Access to DBs 1..255, DW 0 ( DBW 0) .. DW 2047 (DBW 4094) (S5-compatible)
   Access to 15 plcs at the same time, even from the same application. 
 Protocol type can be specified for each plc separately ( V4.0 and later) 
 Server coordinates simultanous access to the plc. 
 scalable speed using Multiport-Access 
 Transmission and receiving fullduplex 
 high Portability of Clientsoftware : Clientsoftware "talks" with CPU Number 0..15,
 only the Server has Informations about IP-Number or Sitename of the plc. 
 Small system resources needed, CPU load less than 1% 
 The usage of the rk*_servers in USA is prohibited. ExplainationWe have thought for a long time if we can do this prohibition, because it could be
understood as a discrimination, but there are diverse reasons for that.One of them: Also in the past, we have always refused to sell to USA and Canada because of the
unpredicable risks coming from the product liability laws of these countries.
 At the end, President Trump also made this decision:
 His statement, to put sanctions on each country which buys oil from Iran, has decided also for us.
 The assumption to be allowed to decide what ever happens  on this planet is widely accepted in all 
parts of the US society.
 We, in opposite, stand on the right to decide for the political orientation of the 
politics of our country for ourselfs. ( see: democracy )
 The only selection of a government which obeys to  supervisory authorities is not acceptable.
 
 We know that our prohibition only can be a sign and the effect of our decition is near
to nothing, else we would hope:
 
 This is not only an action for our security against unwarrantable claims,
it also would be an action
for the  “national security“ of the USA and of course of all other countries.
