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).

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.

• 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) With AS 235 systems, STRUK-AS 220 EA (page 4/9) can also be used for

operations via the CS 275 plant bus (software release G and later)

Ordering data Order No.

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.

The binary extension module 6DS1 719-8RR can be connected

in order to increase the number of binary signal inputs and out-

puts.

Ordering data Order No.
