| Remarks | DEMO = time limited versions. The server process works for 4 hours each time you start it; this should be sufficient for evaluation. Please observe recent bug notification in section News |
 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:
| S7-300 | CP343-1 | S7-Commmunication |
| CP343-1 with Fetch-Write | S7-Commmunication / S5-compat. |
| | ProfiNet-CPU | S7-Commmunication |
| S7-400 | CP443-1 | S7-Commmunikation |
| | CP443-1 with Fetch-Write | S7-Commmunication / S5-compat. |
| | ProfiNet-CPU | S7-Commmunication |
| 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%
