Introduction

January 09 UDA2182 Communications User Guide 1

1. Introduction

1.1 Overview

The UDA2182 provides Modbus communications support on two communication interfaces using the

optional Communication Card.

Serial port provides

•RS422/RS485 multi-drop

•2400 to 115200 programmable baud rate

•Modbus RTU protocol to read signals including PV, Temperature, Alarm Status, outputs, relay

status, etc.

•Read/write four analog and four digital variables (Note 1)

•Can communicate to the P.IE. tool

Ethernet port provides:

•Up to 5 Modbus TCP connections simultaneously

•Ethernet parameters are configured via the front-panel or web pages.

•Web server with up to 10 clients simultaneously

•Web pages (Note 2) setup the Ethernet port settings and monitor readings, alarms, statuses,

events. See Section 12

•Multi-language email to send alarm status changes. Alarm notification to eight email addresses.

These must be configured using web pages signed in as the administrator.

•DHCP: ( Dynamic Host Configuration Protocol) selectable via web page or front-panel

•Firmware upgrade to Main CPU board

•Firmware upgrade to Communications card

•Can communicate to the P.IE. tool

Note 1

There are four analog and four digital variables. These variables can be read and written remotely using

Modbus function codes.

Variables will appear as a selection for various parameters:

•Analog variables can be an alarm source, analog relay source, current output source, monitor

source, math source, auxiliary switch source, PID TRV, and PID remote setpoint.

•Digital variables can be an alarm disable, remote setpoint select, Tune Set2 select, digital relay

source, logic-in source, auxiliary switch select, PID TRC select, PID RSP select, and auto cycle

start source.

Note 2

Web pages (Section 12) provide the following:

•Multiple language support

•“Guest” accessibility for read-only permission

•“Admin” accessibility for read and write permission

•Readings of Inputs, Outputs, and Relay Outputs

•Status of Inputs, Outputs, and Alarms.

•Readings and Status of optional parameters (control, pharma, and auto-cycle)

•List of last twelve events

•Network configuration including IP address, subnet mask, gateway etc.

•Email configuration for alarm event notification

Link Characteristics: Two-wire (half-duplex), multi-drop Modbus RTU protocol, 15 drops maximum or

up to 31 drops for shorter link length.

Modbus RTU slave: Provides monitoring of inputs outputs, statuses, alarms, and variables. Provides

writing of variables for remotely modifying parameter settings.

Ethernet TCP/IP

Communications Interface

(Optional)

Type: 10 or 100 BaseT; auto-speed and auto-polarity sensing

Length of Link: 330 ft. (100 m) maximum. Use Shielded twisted-pair, Category 5 (STP CAT5) Ethernet

cable.

Link Characteristics: Four-wire plus shield, single drop, five hops maximum

IP Address: IP Address is 192.168.1.254 as shipped from the factory

Recommended network configuration: Use Switch rather than Hub in order to maximize UDA Ethernet

performance

Configuration: Ethernet parameters are configured via the front-panel or web pages.

Modbus TCP/IP: Five simultaneous socket connections provide monitoring of inputs outputs, statuses,

alarms, and variables. Provides writing of variables for remotely modifying parameter settings.

Modbus TCP/IP Data Format: IEEE floating point and 32-bit integer. Word swap configurable.

Web server: multiple client support

Web pages: monitoring inputs, outputs, statuses, alarms, and events

Multi-language Email: Alarm notification to eight email addresses. These must be configured using

web pages signed in as the administrator.

DHCP: ( Dynamic Host Configuration Protocol) selectable via web page or front-panel
