The FLEX I/O system is a small, modular I/O system for distributed applications that performs all of the functions of rack-based I/O. The FLEX I/O system contains the following components:

• PROFIBUS adapter/power supply – powers the internal logic for as many as eight I/O modules

• terminal base – contains a terminal strip to terminate wiring for two- or three-wire devices

• I/O module – contains the bus interface and circuitry needed to perform specific functions related to your application

Purpose of the FLEX I/O PROFIBUS APBDPV1 Adapter

The 1794-APBDPV1 module is a FLEX I/O communications adapter that interacts with the FLEX I/O backplane and any PROFIBUS DP master/scanner controller on a PROFIBUS DP network.

The 1794-APBDPV1 module is a slave device to the DP master/scanner, and is a master controller of the FLEX I/O system where it is installed. The I/O data exchange occurs as follows: Output data is sent from the DP master/scanner controller across the PROFIBUS DP network to the 1794-APBDPV1 adapter. The adapter then automatically transfers the data across the FLEX I/O backplane to the output modules. Inputs from the input modules are collected by the FLEX I/O adapter via the backplane and sent across the PROFIBUS DP network to the DP master/scanner controller.

Differences Between APB and APBDPV1 Adapters

This section describes the differences between the 1794-APB FLEX I/O PROFIBUS and the 1794-APBDPV1 FLEX I/O PROFIBUS APBDPV1 adapter modules.

DP-V1 Protocol

The FLEX I/O PROFIBUS APBDPV1 adapter uses a newer version of PROFIBUS DP (DP1) protocol whereas the The FLEX I/O PROFIBUS APB adapter uses the first generation PROFIBUS DP protocol (DP-0).

Functionality

The FLEX I/O PROFIBUS APBDPV1 adapter features Identification & Maintenance (I&M) functions. These functions specify how certain device describing data must be unambiguously stored in PROFIBUS devices essentially enabling easy access to current information on the device. The adapter also supports newer HART modules than the The FLEX I/O PROFIBUS APB adapter.

Bandwidth and Range

The FLEX I/O PROFIBUS APB adapter baud-rate is now 12 MBd and, although the physically PROFIBUS address range is still limited to 1..99, the logical address range is 1..126.

PROFIBUS APBDPV1 Adapter Components

The adapter module consists of the following components:

• two diagnostic indicators

•PROFIBUS DP network connector

• 24V DC power wiring connection terminals

• two node address switches

Diagnostic Indicators

Diagnostic indicators are located on the front panel of the adapter module. They show both normal operation and error conditions in your FLEX I/O system. The indicators are:

• Device status (STATUS)

• Communication link status (PROFIBUS)

Upon power-up, the adapter goes to an initialization state and performs a self-test (memory check, data memory clear, CRC on code). The indicators also go through a self-test sequence. If a failure occurs, the adapter transitions to a faulted state and waits for reset (cycle power). Otherwise, the adapter begins monitoring the network (run state) for messages.

Network Connector

Use the 9-pin SUB-D connector to connect your adapter to the PROFIBUS network.

Set the Node Address Switches

Set the thumbwheel switches to 00 to allow node addressing by software configuration tool to set the range from 1…125. Address changes take effect only after cycling power. Use a pen to press either the + or – buttons to change the number.

Mount and Remove Your System

Power Wiring

Connection terminals are provided for connecting the required 24V DC power to the front of the module. The power wiring can be daisy-chained to the terminal base unit located next to the adapter to supply power to the module installed in that base unit.

Refer to the FLEX I/O PROFIBUS Communications Adapter Installation Instructions, publication 1794-IN114 learn how to install and wire the adapter.

You can horizontally or vertically mount the FLEX I/O system on a standard DIN rail. The adapter and terminal base easily snap on the DIN rail by hand. Refer to the installation instructions shipped with these components.

Screw holes are also provided to horizontally or vertically panel-mount your system in an enclosure. To panel-mount your FLEX I/O system, use the optional mounting kit (1794-NM1). See Example of a DIN Rail-Mounted System

Communication Over the I/O Backplane 9

Polled I/O Structure 10

Map Data into the Image Table 12

Defaults 68

One 1794-APBDPV1 PROFIBUS adapter can interface with up to eight terminal base units with installed FLEX I/O modules, forming a FLEX I/O system of up to eight slots. The adapter communicates to other network system components over the PROFIBUS network. The adapter communicates with its I/O modules over the backplane.

The I/O map for a module is divided into read words and write words. Read words consist of input and status words, and write words consist of output and configuration words. The number of read words or write words can be 0 or more. The length of each I/O module’s read words and write words vary in size depending on module complexity. Each I/O module will support at least 1 input word or 1 output word. Status and configuration are optional, depending on the module.

For example, a 16 point discrete input module will have up to 2 read words and 1 write word.

Refer to each module user manual I/O map for the exact mapping.

Polled I/O Structure

The first word of output data received by the adapter is the Adapter Status Word. Output data is received by the adapter in the order of the installed I/O modules. The Output data for Slot 1 is received first, followed by the Output data for Slot 2, and so on up to slot 8. All bits in the output status word are reserved.

The first word of input data sent by the adapter is the Adapter Status Word. This is followed by the input data from each slot, in the order of the installed I/O modules. The Input data from Slot 1 is first after the status word, followed by Input data from Slot 2, and so on up to slot 8.

Publication 1794-UM064B-EN-P - May 2014

Adapter Input Status Word

The input status word consists of:

• I/O module fault bits — 1 status bit for each slot

• node address changed — 1 bit

0 This bit is set (1) when the node address switch setting has been

changed since power up.

Input Status

Possible causes for an I/O module fault are:

• transmission errors on the FLEX I/O backplane

• a failed module

• a module removed from its terminal base

• an incorrect module inserted in a slot position

• an empty slot

The node address changed bit is set when the node address switch setting has been changed since power up. The new node address does not take effect until the adapter has been powered down and then powered back up. Until this power cycling occurs, the node address switches will not match the actual node address.

Where: F = overload fault bits – 1 = fault present; 0 = no fault

Using the Fault Reset Button When you press the manual reset button:

1. The fault indicator for the faulted output turns off for about 1.2 s (the faulted output will not attempt to turn on during this delay)

2. After the 1.2 s delay, the faulted output attempts to turn on

3. If the external condition causing the fault is corrected, the output remains on, the fault indicator is off, and the status indicator is on

(1)

The unused lower byte in read word 1 floats during operation. Do not use this byte for fault status.

Ox = Output Data (O0 corresponds to output 0, O1 corresponds to output 1, and so on) FR = fault reset bit – 1 = reset output; 0 = no change.
