ABB CSG2003-45A01 Module Bus Options

Description

Dipswitch SW5 sets the controller address, bus speed, and

operation mode (normal/diagnostic). Dipswitch SW2 sets con

troller options, enables special operations, and enables diag

nostic operations. Dipswitch SW4 sets MMU and memory

options.

Jumpers J2 and J3 define controller functions and operation.

Jumper J2 sets the diagnostic RS-232-C port for operation as

DCE or data terminal equipment (DTE). Jumper J3 disengages

-30 VDC from the controller when installing it in a MMU that

supplies -30 VDC to other controllers.

Dipswitch SW3 is not used (refer to

Dipswitch SW3 – Controller Options for more information).

Jumpers J1, J14, and J15 must not be moved from their fac

tory settings. Refer to Table 3-6 for more information.

Dipswitch poles marked not used must be set to the default

settings listed in the appropriate table. The controller may not

operate properly if these dipswitches are improperly set. Since

factory settings do not reflect default settings, it is imperative

that all dipswitch settings be checked before putting the con

troller into operation.

Dipswitch SW5 sets the controller address, enables controller

diagnostics, and sets the bus mode. The controller can have an

address from zero through 31. Table 3-1 explains the func

tions set by dipswitch poles one through three. Dipswitch

poles four through eight set the controller address.

NOTES:

1. SW5 provides a module bus option to support existing INFI 90 OPEN and

early Network 90 systems. All controllers within a process control unit must be

set to communicate on the same type of communication bus, either Controlway

or module bus.

2. Addresses of redundant controllers must be identical.
