Technical Parameters & Selection Criteria

Selection Guidelines: Choose the IC693CPU374 when your application demands Ethernet connectivity without add-on modules, requires 100KB+ program storage, or needs to interface with both modern SCADA systems and legacy serial devices. For motion control applications, consider the IC693CPU360 with dedicated motion coprocessor. For smaller discrete applications (<512 I/O), the IC693CPU331 offers cost savings.

Advanced Integration Options

Common Questions

How does the IC693CPU374 Ethernet interface compare to add-on communication modules?
The integrated Ethernet port provides identical functionality to the IC693CMM311 module but eliminates a rack slot, reduces wiring complexity, and costs 35% less than separate CPU + communication module configurations. Performance is equivalent with 10/100 Mbps auto-negotiation and full Ethernet/IP stack support.

What programming software compatibility should I expect?
Fully compatible with GE Proficy Machine Edition (v9.0 and later) and legacy VersaPro software (v2.05+). Supports IEC 61131-3 languages: ladder diagram, function block, structured text, and sequential function charts. Online edits and program uploads/downloads via Ethernet or serial connection.

Can this CPU handle high-speed counting or motion control tasks?
The IC693CPU374 supports basic high-speed counter inputs (up to 20kHz) through specialized I/O modules like the IC693ACC307. For coordinated multi-axis motion, servo positioning, or electronic camming, the IC693CPU360 motion controller offers dedicated motion coprocessors with 4-axis capability.

What is the maximum network distance for Ethernet connectivity?
Standard Cat5e/Cat6 Ethernet cabling supports 100-meter runs between the CPU and network switches. For longer distances, use industrial Ethernet switches with fiber optic uplinks (up to 2km with multimode fiber, 40km+ with single-mode fiber). PoE switches are not required as the CPU draws power from the rack supply.

How do I migrate programs from older Series 90-30 CPUs?
Programs developed for IC693CPU331/341/351 models upload directly to the IC693CPU374 without modification. Memory-intensive applications may require optimization if exceeding 240KB limits. Use Proficy Machine Edition's "Compare Projects" tool to identify hardware-specific references (communication module addresses) that need updating.

What battery backup options ensure program retention?
The IC693ACC302 lithium battery (3.0V, 950mAh) provides 5+ years of program/data retention during power loss. Battery status monitoring via diagnostic registers triggers replacement alerts 6 months before depletion. Hot-swap capability allows replacement without stopping the CPU or losing program execution.
