What’s faster, smaller, smarter and changing the way OEMs design machines? PointMax I/O modules.
In this FAQ, Hammam Mukhtar breaks down how Rockwell Automation’s PointMax I/O modules work, how they compare to Point I/O and what engineers need to know about compatibility, setup and expansion.
Rockwell PointMax I/O vs. Point I/O
How is PointMax I/O different from Point I/O?
Below are the key differences when comparing PointMax I/O vs Point I/O, especially for OEM machine design and new installations:
- Form factor & I/O Density: PointMax I/O has a 30% smaller footprint than Point I/O and offers higher‑density DI/DO options with 16 channels per module.
- Speed: PointMax I/O modules support gigabit Ethernet and backplane speeds, compared to 100 MB with Point I/O—enabling faster data transfer and response times.
- New Modules: PointMax introduces a new eight‑channel Universal module that supports both fast and standard performance. Each channel can be configured as either an input or an output, allowing a single module to handle mixed I/O needs.
- Communication: PointMax I/O offers Near-Field Communication (NFC) support for registering the product and setting the IP address out of the box.
- Sustainability: PointMax is energy‑efficient and made with more sustainable plastics. Documentation is printed directly on the packaging to reduce paper waste, and status indicators can be turned off when not in use or when the panel door is closed.
- Durability: PointMax I/O XT modules are designed for harsh and corrosive environments. The XT variant features conformal coating for added durability in extreme industrial conditions.
- Power Scheme: The PointMax has a standard base and a base with SA power feed. The SA power feed base is a replacement for the FPD module in the Point I/O.
Is PointMax I/O a drop-in replacement for Point I/O?
No. While PointMax I/O modules are the long-term replacement for Point I/O, they are not a direct drop-in replacement.
PointMax supports newer controllers such as ControlLogix 5580 and 5590 and CompactLogix 5380. Older controllers (L7 or 5370 CompactLogix) still require Point I/O.
Which Rockwell Automation PLCs support PointMax I/O?
PointMax I/O compatibility includes ControlLogix 5580 and 5590 controllers, as well as CompactLogix 5380 systems using Studio 5000 Logix Designer version 36 or later.
Is Rockwell discontinuing Point I/O?
No. Point I/O is still an active product, but we recommend the PointMax for new applications and installations. They will both co-exist for the next couple of years.
How many modules can the PointMax I/O support?
PointMax I/O modules support up to 32 modules per adapter. After the first 16 modules, a PointMax I/O expansion power supply is required to maintain proper power distribution.
When should I use a power expansion supply vs. an SA power feed base?
Until you reach 16 modules, use the SA power feed base once you hit the 10A backplane limit. If there are more than 16 I/O modules per adapter, one expansion power is required after 16 I/O modules.
Both the mounting base (MB) and mounting base with supply power (MBSA) can support all I/O modules.
How many slots can be empty? Do you need ARM module for empty slots?
All 32 slots can be empty if necessary. There is no need for an ARM module, the base will serve as one. You can use fillers (5034-N) if you want to cover the connectors on the bases.
What is the Universal I/O module used for?
The universal card is an eight-channel module where each channel can be configured as input or output. It is ideal for small applications that do not justify separate I/O cards.
What types of modules are available for PointMax I/O?
Right now, it covers about 90% of what is available with Point I/O. That goes for standard modules, like discrete and analog, as well as safety and specialty modules (except for the safety analog and AC cards). Those should be part of the next release, which should cover the remaining 10%.
What is the Universal I/O module used for?
The universal card is an eight-channel module where each channel can be configured as input or output. It is ideal for small applications that do not justify separate I/O cards.
How is the PointMax I/O put together?
PointMax I/O uses a three-piece architecture with the terminal block, module and base as three separate components.
Are PointMax I/O modules hot swappable?
Yes. PointMax I/O modules are hot swappable, meaning they can be safely removed and replaced while the system remains powered on.
The mounting base itself is not hot swappable, and fully removing the terminal block is not required during module replacement.
Where can I find wiring diagrams for PointMax I/O modules?
This is the easiest answer – right on the module! All PointMax I/O modules include printed wiring diagrams on the left side and indicate supported terminal blocks. It makes spec-ing much easier.
What does the Rockwell Automation DeviceTools™ app do?
The Rockwell DeviceTools app for PointMax I/O simplifies commissioning and setup. Using NFC or QR code scanning, users can register devices and complete PointMax I/O NFC IP address setup before installation.
You can even incrementally assign IP addresses to other units by the value you want. It sets the first unit you scan to the main IP address and incrementally adds the rest as you scan through them. Download the DeviceTools app on the Apple app store or Google Play.
