INFO: About rk*_server
run time limitation: Each server process without a licence works for 4 hours each time you start it; this should be sufficient for evaluation.

Please observe recent bug notification in section News

32-Bit-Versions: Actual 32 bit versions of the servers only will be provided on request.
Actually, they is no more demand by clients.
On Requirement feel free to contact us.

rktcp_server rktcp_server Info:

S5/S7 to Linux connection using a communication unit (CP).
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.

Design

The 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:


S7-1500all CPUs S7-Communication
S7-1200all CPUs S7-Communication
S7-300 CP343-1 S7-Communication
CP343-1 with Fetch-Write S7-Communication / S5-compat.
  ProfiNet-CPU S7-Communication

S7-400 CP443-1 S7-Communication
  CP443-1 with Fetch-Write S7-Communication / S5-compat.
  ProfiNet-CPU S7-Communication

S5 CP1430-TCP
S5-Lan, INAT, etc

( 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. Explaination

We 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.
