rk3964_server Info:

S5/S7 to Linux connection using a communication unit (CP).
Uses the procedure 3964(R)

Connects to S7 or S5 plc.

All CPUs can be accessed.

On the Simatic side a device is needed which knows 3964(R). Connection to S7 and S5 is possible, for both families there are communication units (CP) with 3964(R) support. As an alternative S5-CPUs with a second serial interface are available, they all support 3964(R).

Design

The package rk3964_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 . One server supports one client. The server process coordinates the concurrent send and receive accesses to the plc.

A client process can access up to 10 servers.  

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.
