IOB Hardware Reference Introduction CTI Products, Inc.

1. Introduction

The Input/Output Control (IOB) is a member of the Monitoring and Control Network (MCN™) family of auxiliary modules. Hardware specifications, system examples, and configuration information are provided in this manual.

The IOB module connects I/O devices (such as relays) to the MCN network. The IOB is used with a User Interface Module (such as a HIB) to create an I/O control system.

IOB Hardware Reference Theory of Operation CTI Products, Inc.

3. Theory of Operation

This section describes the operation of the IOB module in an I/O control system. This module can operate in one of four different modes:

I/O Group Mode 1 Mode 2 Mode 3 Mode 4

1 2 1 of 4 Select 1 of 4 Select 3# 1 4 Independent 1 of 8 Select 5I/O 6 1 of 4 Select Independent 7# 2I/O 8

The operating mode is set using the OPTION switches on the module’s front panel. Refer to section 4 for a description of the mode setting switches and section 5 for a pinout of the IOB’s I/O connector. The functions of the I/O connector pins on the rear of the module change depending on the IOB’s operating mode.

Each operating mode is discussed in the following sections.

3.1 Controlling the I/O

The MCN HIB module, along with the MCNRCD Remote Comparator Display program, provides a PC based user interface for the IOB module. Output points on the IOB can be controlled by either the PC keyboard or mouse. Input points can be monitored on the screen.

In order to have the MCNRCD software display meaningful I/O status messages, custom status text categories and custom status messages must be created for your specific I/O application (see the appendix titled the Monitoring and Control Network Remote Comparator Display Software Manual (reference 2) for details about creating custom status messages). These custom status messages are defined in the file MCNRCD.CFG.

Section 7 provides a number of examples that show how to customize the MCNRCD display for an IOB module.

3.1.1

Input Monitoring - I/O Groups and I/O Bits

With the MCNRCD software, a single display position on the screen does not represent a single I/O point. Instead, each display position represents the state of four I/O points. We refer to the four I/O points that make up a screen display position as an I/O group (this is similar to the 4 bits, Vote Rx, Disable, and Fail associated with a receiver in comparator applications using a CIB module).

Changing Status Message Text

68-11168-105

IOB Hardware Reference Theory of Operation CTI Products, Inc.

An IOB has 8 I/O groups (similar to the 8 receivers per CIB module). Since each I/O group is represented by four I/O points, a maximum of 32 I/O points can be displayed per IOB. When configuring your MCNRCD screens for IOB modules, know that each I/O group is related to an Rx # in the MCNRCD and MCNCFG software. I/O group 1 is the same as Rx # 1 and so on through I/O group 8 is the same as Rx # 8.

The basic IOB module is setup as 8 I/O groups. Each I/O group has the following 4 I/O lines:

I/O Bit

Type Status Byte

Binary Weight

MCNRCD Input

Status Signal

Output Controlled By

1 Input/Output 01 hex VOTE left mouse button or “V” 2 Input 04 hex RECEIVE N/A 3 Input/Output 10 hex DISABLE right mouse button or “D” 4 Input 40 hex FAIL N/A

Table 2 - I/O Point Binary Weight

Table 2 shows the binary weight of each I/O bit. These binary weights are summed to create the input value fields of the MCNRCD.CFG text definition line. This allows you to display up to 16 status message values for each I/O group (receiver) on the MCNRCD screen. All valid combinations of these binary weights must be defined by separate text definition lines (again, see the appendix

Changing Status Message Text

titled

in the Monitoring and Control Network Remote Comparator Display Software Manual (reference 2) for details about creating custom status messages). Table 3 shows the possible combinations of the binary weights (in the Input Value Field column) and the I/O bit combinations for that value. A column has also been provided for you to enter the text corresponding to the input value field.

In the 1 or 4 and 1 of 8 select configurations, the output for I/O bit 3 is disabled (only the output for I/O bit 1 can be used).

In all cases, any pin not used as an output can be used as an input. Inputs can be dynamic inputs used to sense on and off conditions or can be static “selector” inputs which are permanently strapped to provide a selector function for subcategories.
