Ascent – Smart distributed and peer-topeer 

I/O for monitoring and remote 

control applications: 

• Expand the I/O of a PLC or RTU, and 

add sites to a SCADA or DCS system 

at very low cost 

• Save thousands of dollars of in-plant 

wiring with peer-to-peer wireless, 

serial, or Ethernet I/O. 

• Eliminate costly PLCs, HMIs and 

programming where smart I/O with a 

built-in web HMI will do. 

Supported by most PLCs, RTUs & HMIs 

Ascent can be used with all major PLCs, 

RTUs, and HMI software using Modbus 

TCP/IP, Modbus RTU or DF1 protocols. 

Peer-to 

to-peer I/O Mirroring - Ascent 

Combo and DIO modules can be linked up 

“back-to-back” (up to 8 to 1) to exchange 

sensor and control signals over a secure 

two-way wireless link, external radio, 

modem (via RS-232/485 serial port), or 

Ethernet. Ascent I/O saves thousands of 

dollars in wiring and conduit costs. 

Wireless Store & Forward – Any Ascent 

I/O module can also serve as a repeater to 

extend the effective range of a wireless 

network. 

Local LCD HMI - View and force I/O, and 

make simple configuration changes without 

a computer! 

Web Page Configuration – Ascent I/O 

modules come ready to run, but can be 

customized with a standard web browser 

(like Windows Internet Explorer). No special 

software is required on your PC or laptop. 

Customizable User HMI – Need a simple 

low-cost user interface? Ascent I/O 

includes a simple web-page HMI to save 

you hundreds of dollars in PC-based 

software costs. Web page configuration is 

simple and done in just minutes without 

programming; just fill in the blanks. 

Remote Support – Ascent I/O can be 

reconfigured and customized over a secure 

Ethernet or wireless link, eliminating costly 

field trips and improving customer support. 

I/O can be “forced” via a secure web page 

to facilitate remote troubleshooting. 

Low Power– DC powered Ascent I/O can 

be optimized for battery-backed wireless 

systems with multiple power-saver modes 

and send-on-exception operation.

Modbus or DF1 Serial I/O 

Ascent I/O modules have independent Ethernet, Serial (RS-232 and RS-485) and internal radio (option) communications ports. The 

ports may be used simultaneously. For example, a local Modbus HMI terminal can be connected locally to an I/O module to show 

levels and flows on the door of the panel housing an Ascent module, while an HMI computer or PLC is talking to the Ascent module 

over an Ethernet or wireless link. To extend the effective range of a wireless network, Ascent modules can act as intelligent repeaters, 

using either the internal radios, or external radios connected to the serial port. 

Ascent modules can also bridge communications between ports. In the diagram above, an HMI computer or SCADA PLC can talk to 

Modbus (serial) I/O modules via an Ethernet or wireless connection, or both, saving the cost of additional radios. Bridging is supported 

from Ethernet to serial, Ethernet to wireless, and serial to wireless. 

Ascent I/O Modules “Mirroring” I/O over Ethernet, the Internet, or Wireless Link 

Ascent I/O Combo and DIO modules can also be used in a peer-to-peer or “mirror-mode” configuration where 1 to 8 modules pass 

I/O information to a single Ascent module. Analog and Discrete inputs are “repeated” or mirrored as Analog and Discrete Outputs in 

both directions (2-way). In addition to I/O levels, all tag names, units, etc. as well as associated totalizer, rate and runtime 

measurements are available for display on the local LCD HMIs or by communications at either ends of the links. Mirroring works over 

Ethernet, the Internet, a wireless link, or via external modems or radios connected to the Ascent module serial ports. 

One or more PC computers can 

access local web HMI pages in 

any of the Ascent modules

Ascent I/O 

Combo 

Ascent Combo – a symmetrical mixture of analog and discrete I/O; 

ideal for peer-to-peer mirrored I/O as well as distributed I/O 

applications. In addition, the Ascent Combo module has setpoint 

control, duplex pump control and alarming capabilities, and the 

Universal Inputs may be internally “routed” to the analog outputs to 

function as up to 8 configurable signal conditioners/transmitters. 

8 Universal Inputs 

I 

are individually “soft” configurable through the builtin 

LCD or web page HMI; no switches or jumpers. Each input accepts 

standard process signals (mA, mV or V), measures resistance, and 

reads thermocouples, thermistors or RTD temperature sensors. 

Conversion speed and averaging are configurable on every input to 

optimize response times and noise rejection. Each input can be scaled 

to engineering units. 

8 Analog Outputs provide high-resolution 20mA outputs, or provide a 

voltage output when used with an external resistor. An internal 24v 

loop supply is independent of the supply voltage. 

10 Discrete Inputs – rugged optically isolated inputs available in 12-24v or 120-240v configurations. Each input includes its own nonvolatile 

32-bit totalizers and runtime accumulators, for keeping track of total flow or machine cycles, and motor and pump runtimes. In 

addition, pulse rates are calculated on each input, either by measuring the number of pulses over time period, or measuring the 

interval between pulses (Rate = 1/Time). The method used depends on the input frequency range and the desired update rate and 

measurement resolution. All measurements can be scaled to engineering, offloading calculations from a host PLC. This provides a 

meaningful user friendly display on the local LCD HMI and built-in web page HMI. 

10 Discrete Outputs provide relay dry contacts with programmable flashing, precision one-shot pulse and PWM control.

Ascent I/O 

UI-32 

Ascent UI-32 

– providing 32 Universal Analog Inputs. Each of the 

inputs are individually “soft” configurable through the built-in LCD or 

web page HMI; no switches or jumpers. Each input can be scaled to 

engineering units, offloading calculations from a host PLC. This 

provides a meaningful user friendly display on the local LCD HMI and 

built-in web page HMI. 

32 Universal Inputs, individually “soft” configurable through the built-in 

LCD or web page HMI - no switches or jumpers. Each input may be 

configured to accept standard process signals (mA, mV or V), 

resistance, or thermocouple, thermistor or RTD temperature sensor. 

Conversion speed and built-in box car averaging are also configurable 

by channel in order to optimize response times and noise rejection. 

This also helps to offload processing overhead from PLC or DCS 

systems. 

Each group of eight inputs can be sampled up to 4000 times per 

second for an aggregate maximum sampling rate of 16,000 readings 

per second across all 32 inputs! The high conversion speed combined 

with a high-speed Ethernet interface makes these modules ideal for 

large distributed control and monitoring systems. The ability to “talk” 

multiple industry standard protocols makes these modules a low-cost 

alternative to expensive PLC and DCS system analog input modules.

DIO - 22/22 

Ascent DIO-22/22 

– a symmetrical mixture of discrete inputs and 

outputs; ideal for peer-to-peer mirrored I/O as well as distributed I/O 

applications. 

22 Discrete Inputs – rugged optically isolated inputs available in 12- 

24v or 120-240v configurations. Each input includes its own nonvolatile 

32-bit totalizer for keeping track of total flow or machine cycles, 

and a non-volatile 32-bit runtime meter, to keep track of motor and 

pump runtimes. In addition, pulse rates are calculated on each input, 

either by measuring the number of pulses over time period, or 

measuring the interval between pulses (Rate = 1/Time). The method 

used depends on the input frequency range and the desired update 

rate and measurement resolution. All measurements can be scaled to 

engineering, offloading calculations from a host PLC. This provides a 

meaningful user friendly display on the local LCD HMI and built-in web 

page HMI. 

22 Discrete Outputs provide relay dry contacts with programmable 

flashing, precision one-shot pulse and PWM control functions. The 

flashing function provides a synchronized flash output whose time 

period is programmable, but common to all flashing outputs. This is 

used primarily to operate flashing alarm indicators. Every output also 

supports a one-shot pulse function; each time the channel is activated, 

the output turns on for a precision length of time, and then turns off 

automatically. This type of operation is frequently used with motorized 

actuators to move them a prescribed distance, independent of 

communications latency. The outputs also support PWM (Pulse Width 

Modulated) operation, where the output toggles on and off for a 

precision period of time, and where each channels on and off time can 

be set independently. This operation is used for heater and metering 

pump controls, frequently as part of some closed loop control system.

DI - 44 

Ascent DI-44 

– a Discrete Input module that provides an economical 

means of monitoring a large number of Discrete Input sensors at a 

location. Local processing offloads most realtime response constraints 

of communications without missing a single transition or accurately 

measuring rates and runtimes. 

44 Discrete Inputs – rugged optically isolated inputs available in 12- 

24v or 120-240v configurations. Each input includes its own nonvolatile 

32-bit totalizer for keeping track of total flow or machine cycles, 

and a non-volatile 32-bit runtime meter, to keep track of motor and 

pump runtimes. In addition, pulse rates are calculated on each input,
