SIWAREX M

SIWAREX M

■Overview

In a process engineering application, SIWAREX M handles exe- cution of all weighing functions as well as the time-critical control of the dosing units (valves etc.) of dosing scales, independent of the time cycle of the automation system. Exact switching-off of the dosing valves is achieved in this manner, and thus an opti- mum of dosing accuracy.

SIWAREX M can be used to design net weight scales, single- component or multi-component scales, as well as multi-scale systems.

The downloadable SIWA driver block integrates the SIWAREX M weighing and dosing electronics with verification capability into the TELEPERM M process control system.

The SIWAREX M function modules are operated in ET 200M dis- tributed I/O systems. It is irrelevant whether the ET 200M is con- nected to the automation system via line 1 or 2 of the PROFIBUS- DP. Up to seven SIWAREX M function modules can be plugged into an ET 200M of standard design with bus connectors. Up to four SIWAREX M function modules can be plugged into an

ET 200M with active bus modules (for the hot swapping func- tion).

■Configuration SIWA driver block

The AS 388/TM and AS 488/TM automation systems additionally require the SIWA driver block for connection of SIWAREX M. SIWA is a standard AS function block with the system type num- ber 138, and can be downloaded into the automation system via a commissioning terminal.

Users can call the following functions using so-called jobs:

•"Measure"

•"Tare"

•"Start"

•"Pause" (stopping of a dosing procedure)

•"Continue" (continuation of a dosing procedure)

Status scanning is additionally possible for diagnostics.

The listed jobs can be activated using operator-accessible ele- ments and via configurable inputs. Following termination of a job by SIWAREX M, the driver block assumes the "Measure" status. Just like other operator-accessible blocks, SIWA also offers a status word which can be acknowledged by an operator system.

Note:

The SIWA driver block can only execute on the automation sys- tem whose serial number is stored in the SIWA software. If the SIWA driver block is subsequently ordered, it is therefore neces- sary to specify the memory card serial number of the automation system on which the SIWA is to be installed.
