This manual introduces the basic usage and functions of STEP 7 automation software, focusing on the corresponding technical and drive control components T400, FM 458-1 DP, SIMADYN D, SIMATIC TDC or D7-SYS.
This manual provides detailed information on the function blocks used in the SIMATIC TDC system, including communication utilities, service/diagnostic blocks, input/output blocks, and closed‑loop control blocks. It is intended for programmers and debugging engineers who need to configure and troubleshoot the TDC system.
The document also contains safety guidelines, version history, and indexing of all blocks. Technical parameters such as allowed input ranges, default values, and sampling times are listed for each block, helping users set up the system correctly. This manual is written in Chinese.
| RTCM sampling interval | 128 ms ≤ TA ≤ 512 ms |
|---|---|
| I/O block sampling time range | 1 ms ≤ TA ≤ 130 ms |
| MOD input range (I/O block) | 0 ≤ MOD ≤ 2 |
| INT_M MOD range | 1 … 230 (default 0) |
The RTCM block can be configured with a sampling interval between 128 ms and 512 ms.
QTS shows whether the block is correctly initialized (QTS = 1) or has become deactivated after a communication error (QTS = 0).
