Closed-loop control modules

Function modules

￿Function modules have their own functions which are indepen- dent of the central unit. They possess backup modes which per- mit operation independent of the central unit.

Some of the function modules are configurable. The firmware of these configurable modules contains an interpreter which pro- cesses a user configuration made up of defined blocks. This user configuration is generated on a personal computer using the STEP M (BG) programming language, loaded into the mod- ule via a serial TTY interface, and stored in an EEPROM. The

STRUK-AS 220 EA program is used as the configuring aid for this purpose (see page 4/9). 1)

Closed-loop control modules

Three different S and K closed-loop control modules are avail- able:

•S closed-loop control module, with 2 PI controllers S, 6DS1 402-8BA

Two-channel, autonomous PI closed-loop controller. Can be used as a fixed setpoint controller in SPC, DDC and backup modes. In backup mode, the controller can be operated using controls on the front panel.

The module detects 3 analog signals and a position feedback per channel.

•S closed-loop control module, two-channel, configurable, 6DS1 411-8RR

Two-channel, autonomous controller which acts directly on the process via power control units. The manipulated variable sig- nal is a stepped output.

The module can be used to implement 2 independent controls (individual controls) or 2 associated controls (master controls) by appropriate configuring.

The closed-loop control module must be configured. The PC is connected via the front plug of the module. 1)

•K closed-loop control module, with 2 PI controllers K, 6DS1 403-8CB

Two-channel, autonomous PI closed-loop controller. Can be used as a fixed setpoint controller in SPC, DDC and backup modes. In backup mode, the controller can be operated using controls on the front panel.

The module detects 3 analog signals and a position feedback per channel. The input signals can be monitored in live-zero mode according to the NAMUR NE 43 recommendation.

•K closed-loop control module, two-channel, configurable, 6DS1 412-8RR

Two-channel, autonomous controller which acts directly on the process via power control units. The manipulated variable sig- nal is a continuous output.

The module can be used to implement 2 independent controls (individual controls) or 2 associated controls (master controls) by appropriate configuring.

The closed-loop control module must be configured. The PC is connected via the front plug of the module. 1)

Calculation modules

•Binary calculation module, configurable, 6DS1 717-8RR, and

binary extension module, 6DS1 719-8RR

Autonomous module for binary logic operations. Application examples:

–Individual control drive (max. 5 channels)

–2-out-of-3 selection with switching off of faulty channel

–Limit formation

–Protective and release interlocks

–Unit switchover.

The calculation module must be configured. The PC is con- nected via the front plug of the module. 1)

The binary extension module 6DS1 719-8RR can be connected in order to increase the number of binary signal inputs and out- puts.
