Hardware Configuration

In order for multiple PPC modules to function together, each

needs to be addressed correctly. Some of the PPC modules may

require jumper or switch settings to work with field input and

output devices. The following sections describe the

configuration options and procedures.

Module Addresses

Each module in a PPC assembly must have a unique address.

The PPC-2010 module is fixed as module address 0 in the

firmware. The other modules’ addresses are set with rotary

switches on the face of each module. Set a unique address on

each module by turning the arrow to an appropriate address

number. See Figure 2.3.

Figure 2.3 Sample Addresses

Table 2.4 on page 18 lists the maximum number allowable of

each type of module per system, as well as the available

address settings. Pay close attention when using more than one

module of a particular type in a system. For example, one PPC

system allows up to four analog input modules (PPC-2021 -

2025) and each must have a unique address setting, as shown

in Figure 2.3.

CAUTION!

If address settings are changes, modules added or

removed after the system has been initialized,

modules may not function correctly. To assure proper

operation, perform a RAM Clear after changing the

number of modules or address settings in a PPC

system. Refer to Chapter 4, Resetting Closed-Loop

Control Parameters on page 156.

NOTE!

It may be useful to label each module with the address

you select.
