ABB Processor 958481321200 350211080320 CPU Module

The ABB Processor 958481321200 (350211080320) is a mid-range CPU module for the ABB AC500 PLC platform. It balances processing power, memory, and cost, making it ideal for applications requiring moderate I/O counts and network connectivity. Typical uses include packaging machines, conveyor control, and small process skids.

Memory and Performance

The 512 KB program memory can store up to 10,000 function blocks. The data memory includes retentive variables that survive power cycles without battery backup for 30 days. The CPU supports up to 16 tasks with configurable cycle times (minimum 1 ms). The integrated Ethernet port supports programming, HMI communication, and Modbus TCP.

Expansion and Fieldbus

The CPU can be extended with up to 8 local I/O modules and up to 32 remote stations via CANopen or PROFIBUS DP. The RS-485 port can be configured as Modbus RTU master/slave. The CPU also supports a second Ethernet port via an optional communication module.

Application Domains

This CPU is commonly used in packaging lines, small assembly stations, agricultural machinery, and building automation. It provides a cost-effective solution for applications that need Ethernet connectivity but do not require high-end redundancy features.
