PRODUCT OVERVIEW
This section contains functional, physical and communication charac-
teristics of the controller.
Functional Description
The Type SLC Strategic Loop Controller is intended for small process
control applications and easily accommodates simple PID functions
to very complex multiloop control strategies. It can be used as a
stand-alone product, in conjunction with other Command Series®con-
trollers, or as a component that can interface with ABB’s powerful
INFI 90®Open strategic process management system or the
Network 90®distributed control system.
On-board, factory configuration can be set up and tuned from the
faceplate.
Custom control strategies can be implemented using an external con-
figuration device such as the handheld Type CTT Configuration and
Tuning Terminal, the PC-based ABB engineering work station, a PC
equipped with the CCAD01 Command CAD Configuration Tools
(Release 2.0) or WCAD01 Module Configuration Tools (Release 2.0).
These devices access a library of control algorithms contained in con-
troller memory called function codes. The function codes are

assigned to a block address in the user-definable space of controller
memory. Assigning a function code to a block address forms a func-
tion block. Control configurations are built by forming function blocks
and linking them together.
Menu-driven screens provide quick setup and unparalleled process
interface. Refer to Figure 1-1 and the following descriptions of the
main menu items.
FULL/SPLIT SCRN Full screen process display shows the process variable (PV), set
point (SP) and control output (CO) of one loop (either loop can be dis-
played). The operator can interface to the displayed loop.
Split screen process display shows the PV, SP and CO of both loops
simultaneously. The operator can interface to both loops.
MONITOR Numerically displays all I/O and four function block outputs. It also
includes a STATUS menu item that includes diagnostics and software
revision levels.
ALARM SUM Provides clear, concise alarm descriptions.
BYPASS Locks in a manual override capability on both analog outputs.
TUNE Provides quick access to the PID tuning parameters and to adjustable
alarm settings.
D.O. CTRL Provides faceplate control of the four digital outputs.
AUX. SWITCH Provides four auxiliary faceplate switches which can be used for trou-
bleshooting or in the control strategy.
SETUP Allows determining:
•Process display screen options.
•Module bus address (0 to 31).
•Password security options.
•Diagnostics to verify hardware.
•Special optional temperature/frequency input board setup.
•Selection of trend screen options.
•Display brightness.
•Baud rate and data framing for serial interface.
CONFIGURE Provides the menu-driven screens necessary to implement a factory
configuration.

INTRODUCTION
PRODUCT OVERVIEW
1 - 4
Physical
The controller is a panel-mounted, slide-out assembly that conforms
to DIN standards. The assembly contains four printed circuit boards
(main board, operator interface board, power supply board and termi-
nation board) and a faceplate assembly (Fig. 1-2). The operator inter-
face board is attached to the faceplate assembly and is connected to
the main board via a 26-pin ribbon cable connector. Both the power
supply board and the main board plug into card edge connectors on
the termination board. The termination board is assembled to the rear
of the housing and provides plug-in terminal blocks for easy access
when making wiring connections in the field. The terminal blocks are
keyed and marked to prevent possible customer connection errors.
Type SLC22_ controllers have an optional input board for low level or
frequency/pulse inputs. It connects to P6 on the main board. Type
SLC_21 controllers have a serial interface board that allows termina-
tion board access to the serial interface at the rear of the controller.
The serial interface board connects to P7 and P8 on the main board.
The housing is welded sheet steel and contains card guides that are
riveted to the housing for installing the circuit boards. Multiple knock-
outs at the rear of the housing provide two ½-inch and one ¾-inch
conduit entrance facilities for electrical interconnections. The housing
also contains multiple holes in the top and bottom primarily for heat
dissipation.

INTRODUCTION
PRODUCT OVERVIEW
1 - 5
Two captive mounting brackets, one for the top and one for the bot-
tom, are supplied with each controller. When in position, the mounting
bracket secures the controller to the panel.
A captive locking screw (Fig. 1-3) located behind the door on the
faceplate must be loosened to remove the faceplate and operator
interface board assembly from the housing. Also located behind the
access door is the connector for the Type CTT Configuration and
Tuning Terminal or the serial interface adapter, and a controller reset
button.
Communication System
The Type SLC Strategic Loop Controller has peer-to-peer communi-
cations capability via the ABB module bus network. The module bus
can transfer approximately 600 to 700 real points (a mix of analog
and digital) per second. The network can contain up to 32 address-
able modules/controllers, enabling over 60 loops of control.
Controllers on the network can be linked to a PC through the
stand-alone Type CIC01 Computer Interface Command Module (Fig.
1-4). Tools such as the ABB engineering work station software and
LAN-90®Process Control View (PCV®) can be used.
The serial interface allows connection to a PC without the use of the
Type CIC01 module (Fig. 1-5). This allows the use of a PC equipped
with Bailey-Fischer & Porter CCAD01 Command CAD Configuration
Tools (Release 2.0) or Elsag Bailey WCAD01 Module Configuration
Tools (Release 2.0).

ABB or have a definition that is different from standard industry
usage.
REFERENCE DOCUMENTS
Table 1-1. Glossary of Terms and Abbreviations
Term Description
Cascade Station An analog control station configuration that allows an externally generated signal, such
as the output of an upstream controller, to control the set point. One of three station
types available in the normal operating mode.
Fatal Error An error that causes the device to go into a fail mode and send its output to a defined
value.
Function Block The occurrence of a function code at a block address of a module.
Function Code An algorithm which manipulates specific functions. These functions are linked together
to form the control strategy.
Loop That portion of an analog process control loop which resides within the controller and
typically consists of an analog input measuring the process variable, a manual/auto
station generating a set point, a PID control algorithm and an analog output driving a
final control element.
Module Bus Peer-to-peer communication link used to transfer information between intelligent
modules within a process control unit.
Ratio Station An analog control station configuration that maintains a ratio between two variables. The
ratio of an externally generated wild variable times the controlled variable becomes the
set point that provides regulation of a third variable. One of three station types available
in the normal operating mode.
Termination Unit Provides input/output connection between plant equipment and INFI 90 Open/
Network 90 modules.
Wild Variable A variable that is used as a reference for a control loop.
