This document describes the features and usage of Siemens' continuous temperature controller FB 58 “TCONT_CP” and step temperature controller FB59 “TCONT_S”.
The manual provides an overview of the PID temperature control function blocks available in the SIMATIC standard library. It describes the purpose, scope, and required knowledge for using FB58 (continuous controller) and FB59 (step controller) with STEP 7 V5.1 or later.
It includes detailed chapters on controller structure, parameter scaling, tuning procedures, example applications, and appendices with technical specifications, abbreviations, and an index. Safety guidelines, qualified‑personnel requirements, and support information are also provided. This manual is written in Chinese.
| Input scaling factor for thermocouple / PT100 / NI100 | 0.1 |
|---|---|
| Input scaling factor for PT100 / NI100 (climate) | 0.01 |
| Input scaling factor for voltage/current (%) | 100/27648 |
| Deadband (DEADB_W) default behavior | 0.0 disables deadband |
| PV_FAC calculation for -20 °C to 85 °C range | 0.9524 |
The manual applies to STEP 7 programming software V5.1 and later, including Service Pack 3.
Only qualified personnel are permitted to install and operate the device.
Technical support is available through Siemens representatives, regional training centers, and online portals such as www.ad.siemens.de.
