Operating Modes

The

SIMA

TIC 505 Isolated Interrupt Input Modules have 16 discrete input
circuits and operate on different voltages depending on the module. The
PPX:505–4317 operates on 24 VDC, the PPX:505–4318 on 48 VDC, and the
PPX:505–4319 on 125 VDC. Up to 8 of the 16 points can be configured as
interrupt points. Isolation is provided between each point. The modules
operate identically except for differences in input voltage.

The Interrupt Input Modules are compatible with all Series 505 bases.

The Interrupt Input Modules are compatible with all SIMA

TIC 505 CPUs

when used in the non-interrupt mode.

When interrupt mode is selected for any of the configurable inputs, the
module is compatible with the SIMA

TIC 545 and 555 CPUs with Firmware
Release 2.1 (or greater). Consult the release notes or other associated
documentation to determine if interrupt mode is supported by a particular
CPU.

The Interrupt Input Modules sense incoming DC signals from field devices
and operate on power supplied by the I/O base backplane. Refer to your
system manual for instructions on supplying power to the system I/O base.

The Interrupt Input Module can be used in one of the following two modes.

Optional T

ime

Constant Filter

•

16 isolated discrete inputs, all

non-interrupt

mode:

When this module is used in non-interrupt mode, it functions as a
standard 16-point discrete input module and can be installed in any
base (local or remote) of a Series 505 programmable controller system.

•

Configurable mix of

interrupt

inputs and non-interrupt inputs:

When this module is used in interrupt mode, it functions as a 32-point
I/O module (16 physical inputs and 16 internal points) and can only be
installed in the

local

base

of the system. Local Base is defined as the

I/O base containing the CPU.

Interrupt input mode triggers an immediate response to a field device
condition without having to wait for the CPU to complete its program scan
cycle.

Y

ou can configure the module to detect transitions from on to off, off to on,

or either edge when you select interrupt type for a pair of input points.

An eight-position dipswitch allows you to enable a 10-ms filter on any of the
16 physical input points in groups of two.

Product Overview

SIMATIC 505 Interrupt Input Module User Manual

Physical Featur

es

The

Interrupt Input Modules have two groups of dipswitches located at the
top of the board, as shown in Figure 1-1. The module includes a standard
input terminal connector which can be detached from the module without
having to remove the module from the base. An LED array on the faceplate
shows input status for each point and also interrupt enable mode.

Manual Contents

Chapter 2 describes how to configure the dipswitches, wire the terminal
block, and install the module.

Chapter 3 describes the basic operating features and the use of the LED
array for reading the status of the inputs.

both non-interrupting and interrupting. The 10-ms filter may be useful in
applications where relay chatter or switch bounce is a potential problem.

Filtering delays module response time to input transitions. For

Interrupt Input Modules are single-wide and may be installed in any
available slot for single-wide modules. Do not touch the printed circuit
board (PCB) while inserting the module. This could cause electrostatic
damage to its components. To insert the module, follow these steps.

1.

Position the module so that the front bezel is facing you.

2.

Hold the top and bottom of the bezel and slide the module carefully into
the slot, pushing it all the way into the base. If you have inserted the
module correctly

, you will feel a slight increase in resistance as the

module mates with the backplane connector

3.1 Operational Description

Using

the Module
in Non-Interrupt
Mode

If

you decide to use the Interrupt Input Modules in an application that does
not require interrupt inputs, and you have selected the
switch

settings for each of the interrupt point pairs, then the module enters

Non-interrupt Mode when power is applied to the base.

In this mode, the module can be installed in any base (local or remote) of the
system and is recognized by the CPU as having 16 discrete input (X) points,
all of which are available for field connection.

No Interrupt

Using the Module in Interrupt Mode

If you selected an interrupt type for at least one of the pairs of configurable
input points, then the module enters Interrupt Mode when power is applied.
In this mode, the module can only be installed in the local base (the I/O base
containing the CPU module) and is recognized by the CPU as having 24
discrete input (X) points and 8 discrete output (Y) points.

In Interrupt Mode, the points are defined as follows.

•

Points 1 – 8: Non-interrupting field inputs

•

Points 9 – 16: Configurable (interrupting or non-interrupting) field
inputs based upon the settings of the interrupt switches on the module

•

Points 17 – 24: Logical (internal) status inputs that, when set by the
module, report to the CPU which point has generated an interrupt as a
result of a field input transition. Each of these points corresponds to
one of the interrupting field inputs, as shown in T

•

Points 25 – 32: Logical outputs that act as individual interrupt enables
for each of the interrupting field inputs. T

SIMA

TIC TI545/TI555 System

SIMA

TIC TI505 Programming

Basic Outline of Interrupt Processing

The Interrupt Input Module and the CPU work together to process
interrupt signals in the following manner

1.

When a field signal connected to an interrupt input transitions in a

.

manner that matches the interrupt type selected for that input, the
module sets the corresponding interrupt status input point and
generates an interrupt to the CPU.

2.

The CPU detects this interrupt, and, if proper qualifying conditions are
met, executes the interrupt RLL program, provided the CPU is in Run
Mode.

3.

The CPU automatically issues a rearm signal to the module to clear the
current interrupt event and to allow new events.

4.

If an interrupt transition occurs at a given input point while the CPU is
currently processing an interrupt event, the module holds the new
event until the CPU issues the rearm signal to complete processing of
the current event. The module then generates another interrupt to
signal the CPU that a new event has occurred.

NOTE:

is

If an interrupt transition occurs at an input point while the module

holding

an event from the

same

input point, the new event will effectively
be lost, since the module will only generate a single interrupt to the CPU.
This behavior is significant only in pulse-counting applications, where
pulses could potentially be missed if the pulse frequency is too high. Refer to
your CPU’s Release Notes

for specifications on execution times.

The input status LEDs indicate the state of the input from the logic (PLC)
side, not from the field side. When an input is on, a corresponding LED
turns on.

The interrupt enable LEDs indicate the status of the interrupt enable
logical outputs (points 25 – 32), which enable or disable the interrupt
operation for input points 9 – 16. Interrupt enable status of points 9 to 16 is
indicated by the status of LEDs C5 to C8 and D5 to D8.

These LEDs can be used to check normal module operation as well as to
troubleshoot when unexpected results are experienced.
