MODULE BUS ADDRESS SELECTION/SELF-TEST SWITCH (S4)
In order to communicate with the system, each module must
have a unique address. Switch S4 positions four through eight
are used to set the module address and are listed in Table
The COM can have one of 32 addresses (address 0 to 31) on the
module bus. This address uniquely identifies the controller
module (COM) and must be the same as the address set in the
configuration.
The address is set by the eight position address dipswitch (S1)
shown in Figure
. The five right switch positions (4 through
8) of S4 set the six bit COM address. Positions 1,2 and 3 are not
used and must remain in the closed position (see Figure 3-2).
Table
is a binary address conversion table for setting S1.
DIGITAL INPUT JUMPER SETTINGS
Three jumpers are used to condition the Digital Inputs for
either 24 VDC or 125 VDC. They are J1 for Digital Input Num-
ber 1, J2 for Digital Input Number 2, and J3 for Digital Input
Number 3. Figure
shows how to set these jumpers for the
desired digital input.
EDGE CONNECTORS
P1 - Receives and applies power to the module and enables
interfacing with the module bus.
P2 - Not used.
P3 - Receives inputs from, and outputs to, the field via the
NKTU01 cable, and provides interfacing to the analog control
stations.
CONFIGURING NVRAM
The NVRAM (battery backed memory) holds the configuration
data (Function Blocks). This type of memory is used because it
