Description

Enlarge

The TD 400C is an especially flexible HMI device for the SIMATIC S7-200. The display can either be configured with four lines and 24 characters per line or with two lines and 16 characters per line. The 15 configurable keys provide tactile feedback, additional visual or acoustical feedback can be set up. The design of the device surface can be individually arranged around the permanently positioned keys.

Area of application

The TD 400C is suitable for simple to more complex operating tasks with the SIMATIC S7-200 PLC; longer alarm texts and a limited number of functions can also be configured.

Benefits

Design and functions

The TD 400C is simply connected to the PPI interface of the S7-200 via the supplied connection cable. A separate power supply is not necessary. It is also possible to connect multiple TDs to an S7-200.       

If the distance between TD 400C and S7-200 is greater than 2.5 m, an AC adapter for the power supply is required. Instead of the connection cable, PROFIBUS bus lines are then provided.

The configuration data of the TD 400C is stored in the CPU of the S7-200. The alarm texts and configuration parameters are created with the programming software STEP 7-Micro/WIN V4 SP 6 (TD 400 Wizard). Additional parameterization software is not needed.
