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
