PRODUCT DESCRIPTION

2.3 Interfaces

● Standard:

– 3 analog interfaces for measured value output

– 2 digital interfaces for maintenance requests or malfunction messages

– RS-485: Either Modbus-RTU or SICK bus to the TAD control unit

● Optional:

– PROFIBUS DP-V0

2.3.1 Analog interfaces characteristics

The interfaces of the VISIC100SF provide 4 ... 20 mA signals. If an error exists on the

VISIC100SF or when the measured value underflows the lower measuring range limit, the

relevant analog output switches to 1 mA. If the upper measuring range limit is exceeded,

the relevant analog output switches to 23 mA.

The following formula shows the relation between the output current and the respective

measured variable:

2.3.2 Digital interfaces properties

If a device error is detected or a measured value is outside the measuring range, an error is

signaled via the malfunction relay. If no device error exists, the malfunction relay is in a

closed state. The relay opens when an error occurs.

2.3.3 Modbus-RTU interface characteristics

see “Modbus-RTU (integrated in the VISIC100SF standard version)”, page 39.

The switch to 1 mA only affects the analog output with a device error. All other analog

outputs continue to output a measured value between 4 ... 20 mA.

The analog interface can deliver a load of up to 500 Ohm.

The refresh rate is ≤ 1.6 seconds.
