Setting the Module, Configuration, Jumper | Siemens 505-2557

All of these advanced function options are designed to be stored in the

controller in a V-memory or K-memory table and downloaded to the module.

The advantages of this method over a communications port on the module

are greater flexibility, easier maintenance, and reduced documentation.

The controller can change any function ªon the flyº if changing process

conditions require (for example, a process needs tighter control, therefore

narrower alarm limits). Any replacement module can be downloaded from

the controller, which eliminates the need for a cable, a laptop computer and

the most recent documentation.

Setting the Module

Before you begin to use the advanced mode of the SIMATIC 505±2557, all of

Configuration

the hardware functions, such as voltage range input levels, type of RTD, _C

Jumper

or _F, etc., should be set up in accordance with the instructions in Chapter 1

and Chapter 2.
