INTERRUPT INPUT MODULE
GENERAL
The Interrupt Input module allows the user to initiate the
execution of a subroutine by activating an input. (A subroutine can also be initiated by a user-program
function.) By Series Six convention, a subroutine is a sequence of functions separate from the main program that
is solved, only when required, by the Programmable
Controller.
The Interrupt Input module can be utilized in a CPU I/O
station or a Local I/O station. A Model 60 CPU or Model
600 CPU can support one Interrupt Input module, whereas a Model 6000 CPU can support two modules: one in a
primary I/O chain, another in an auxiliary I/O chain. The
Interrupt Input module features and benefits are summarized in Table 1.
Each module provides eight inputs. The inputs are organized into four groups of two, with an isolated neutral for
each group. In series with each input is an LED that indicates current flow through the input circuit.
TABLE 1.
DESCRIPTION
The inputs can respond to rising-edge transitions or
falling-edge transitions. The edge response of an individual input is jumper-selectable by the user .
In a primary I/O chain, the module inputs, Nos.l-8 (I/O
points I1001-Il008),
correspond to subroutines, Nosl-8,
resident in the user program. However, in an auxiliary
I/O chain (which can only be connected to a Model 6000
CPU), the module inputs, Nos.l-8 (I/O p o i n t s
11009-11016),
correspond to subroutines, Nos.9-16, in the
user program.
Interrupts are serviced by the CPU on a first-come, firstserve basis. When two or more interrupts occur
simultaneously, the lowest-numbered interrupt is serviced first.
Refer to Figure 1 (next page) for Interrupt Input module
specifications.

INSTALLATION
The Interrupt Input module can be installed in any position of an I/O rack in a CPU I/O station or Local I/O
station. (A Model 60 CPU-based system contains I/O
slots within the CPU rack.) The module address is hardwired on the circuit board to equal 125, decimal (FD,
hexadecimal). Consequently, the values of the DIP
switches on the rack backplane adjacent to the I/O slot are
ignored by the CPU.
Before inserting the module in the I/O rack, the user
should inspect the placement of the eight, blue-plastic
jumpers on the circuit board (Refer to Figure 2, User
Item No. 2). These jumpers allow the user to select the
edge responses of the eight inputs. The module is shipped
from the factory with the eight inputs set to respond to
rising-edge transitions. (The jumpers are inserted between
middle terminals and the N terminals.) The user can
direct any given input to respond to a falling-edge transition by inserting the associated jumper between the
middle terminal and the I terminal.
We recommend that you use the extraction/insertion tool
furnished with your CPU to remove or install the circuit
board. With the board in place in the rack, the edge
connector on the faceplate should be slipped over the circuit board so that proper contact is made. You can then
secure the faceplate to the rack using the thumbscrews at
the bottom and top.
Refer to Figure 3, Typical User Connections. The Interrupt Input module inputs are connected to user-provided
10 - 30V DC power supplies. The switching device that
activates an input must be in series with the power supply.
In this scheme, one side of the switching device is connected to the input, the other side is connected to the positive terminal of the 10 - 30V DC supply; the negative
terminal of the power supply is connected to the neutral
terminal associated with the input.
For the purpose of electrical isolation, as few as two inputs
can be connected to a single 10 - 30V DC supply.
Otherwise, up to eight inputs can be connected to a single
lo- 30V DC supply.
NOTE
We recommend that you power-down
your Series Six Programmable Controller before installing or removing
the Interrupt Input module. A parity
error could result at any address in the
I/O structure if you do not power-down
as recommended.
