| Summary: |
| The Siemens SINEC-TF protocol is supported with two drivers, the SINEC Driver and the new TINEC driver. This article addresses who can talk to what and which combinations are valid. |
| Solution: |
| The Citect protocol driver SINEC talks to
Siemens S5 PLCs supporting SINEC-TF (layer 7). This protocol can be
used for both the H1 (Ethernet) and the L2 (RS-485 network). H1 and
L2 require different hardware and different low level driver
software (ie TSR's and firmware from Siemens).
The Siemens TI PLCs now have a NIM which supports H1 (Ethernet). The driver for this PLCs will be available in Citect version 3.0 or may be obtained from Citect Support. This driver will eliminate the complicated data definition required for the S5 PLCs. It uses the same data types as the existing TIWAY driver. The TINEC and SINEC drivers can not be run together on the same IO Server. This restriction is due to a software issue in the TF library used for the driver. A single IO Server can carry up to 2 cards supporting H1 or L2. Only addresses 0xD000 and 0xE000 are permitted for the cards. Both the SINEC and TINEC Drivers will support two cards. however NO increase in performance will be achieved. Mixing H1 and L2 on the same IO Server is NOT recommended. Even if it works the performance of the H1 will be limited by the speed of L2. According to Siemens documentation Siemens H1 card (CP5413) can simultaneously run the SINEC-TF-H1 protocol and a PC networking protocol. Currently we have not been able to get this feature to operate. Support for the following is documented:
