Technical Features & Benefits
The IC693372-AE is a central processing unit designed for the Series 90-30 modular PLC family. It brings enhanced Ethernet networking, increased processing power, and integrated diagnostics into legacy control systems. With the two onboard RJ-45 ports supporting 10/100 Mb/s auto-sensing, it allows the PLC to join modern Ethernet networks, exchange data via Ethernet Global Data (EGD), and supports web-based monitoring functions.
From a processing standpoint, this module uses a 133 MHz-class CPU (often referenced as AMD SC520 or similar 386EX derivative) that gives a Boolean execution time around approximately 0.15 µs per instruction under typical conditions. This allows the logic to handle moderate complexity and I/O counts without being bottlenecked.
For installations with existing Series 90-30 racks and I/O modules, the IC693372-AE is attractive because it provides a modern network interface without requiring a full platform migration. You retain your I/O modules, wiring, and software environment (Logic Developer / Proficy Machine Edition), but gain Ethernet capability and improved diagnostics.
On the diagnostics side, the built-in web server allows viewing I/O fault tables, status bits, and reference tables via a standard browser—helping maintenance teams monitor system health remotely. Because of this, the module supports more proactive maintenance practices.
One practical benefit we’ve observed is that in a retrofit scenario, replacing an older CPU with the IC693372-AE resulted in fewer surprises during commissioning because the Ethernet diagnostics immediately flagged mis-wired modules and I/O mismatches early.
However, note that while this CPU offers solid performance for the Series 90-30 family, it is not on par with newer PACSystems (RX3i) controllers or high-end motion controllers in terms of throughput, advanced motion capability or memory size. For very large systems (tens of thousands of I/O points) or heavy floating-point/motion tasks, you might still consider a newer platform.
