What does this processor adaptor do in a Modicon Momentum system?

It acts as the CPU/communications adaptor that mounts onto a Momentum I/O base, providing control execution plus network connectivity so the I/O base can be used as a functioning controller node.

Which Modicon Momentum hardware is it intended to be used with?

It is designed for the Modicon Momentum automation platform and is powered by (and installed on) a Momentum I/O base, forming a compact PLC station.

What communication interfaces are available?

It provides one Ethernet port and one RS485 port, enabling Ethernet-based communications as well as serial Modbus connectivity depending on how it is integrated.

Which industrial protocols does it support over Ethernet?

Over Ethernet it supports Modbus TCP messaging and I/O scanning, which are commonly used for exchanging data with HMIs, SCADA systems, and other Modbus TCP devices.

Does it support Modbus over serial as well as Ethernet?

Yes. In addition to Modbus TCP over Ethernet, it includes an RS485 interface used for serial Modbus communications.

How is the adaptor powered?

It uses a rated supply voltage of 5 V DC (±5%) and is supplied by the Momentum I/O base it is fitted to—no separate power input is required on the adaptor itself.

What processing performance should I expect?

It uses an x86-based processor running at 50 MHz, with a published execution time of 1 ms per 1K instruction for typical workload comparison.

How much memory is built in?

It includes 544 kB RAM and 512 kB Flash. The memory allocation includes 24 kB data and 18 kB program memory (LL984).

What I/O capacity can it handle?

It supports up to 8,192 discrete inputs and 8,192 discrete outputs, and up to 26,048 registers (I/O capacity figures are dependent on the configured system and application).

What web-related functions are available on the Ethernet interface?

It includes embedded web services such as a data editor, rack viewer, and web page loader functions to assist with viewing and interacting with the node over the network.

What environmental operating limits does it have?

It is specified for operation from 0 to 60 °C, storage from -40 to 85 °C, and 5% to 96% relative humidity (non-condensing), up to 2,000 m altitude.

What certifications and approvals are associated with this adaptor?

It is listed with UL and cUL and includes approvals such as FM Class 1 Division 2 and NEMA Type 250 (marking includes CE). For reference, this unit is commonly identified as 171CCC98020.
