I.Product Overview
Model:SCYC26901
Brand:ABB(a global leader in industrial automation and power technology)
Type****:Industrial controller module(integrated CPU,I/O interfaces,and communication functions)
Core Positioning:
Serves as the master control unit of a distributed control system(DCS)or programmable logic controller(PLC),responsible for real-time data acquisition,logic control,sequential control,and other tasks.
Suitable for cost-sensitive but high-reliability applications such as water treatment,HVAC,packaging machinery,and light industrial equipment.
Series:
Possibly part of the AC 800M Compact series(compact controllers)of the ABB 800xA system or the MasterBus 3000 economy series of the Advant Master system(specific system confirmation required).
The SCYC prefix typically stands for System Control Unit,and 26901 is the model code(which may relate to processor performance or I/O capacity).II.Core Functions and Technical Features
1.Basic Performance Configuration
CPU Architecture:
A 32-bit processor(such as the ARM Cortex-M series or a low-power x86 architecture)with a clock speed of≥400MHz is used to meet basic control logic requirements(such as PID control,timers,and counters).
It does not integrate a dedicated floating-point unit(FPU),but supports simple floating-point operations through software optimization.
Memory Configuration:
RAM:≥128MB(expandable to 256MB on some models)for real-time data caching.
Flash Storage:≥256MB for storing user programs,historical data,and system configurations.
Real-Time Performance:
Task scheduling cycle≤50ms,suitable for non-high-speed dynamic control scenarios(such as temperature,pressure,and liquid level control).
2.Modularity and Scalability
I/O Interfaces:
Built-in I/O:Supports 8-16 digital inputs(DIs)/outputs(DOs)or 4-8 analog inputs(AIs)/outputs(AOs)(specific quantity depends on model variant).Expandability:Up to 64 external I/O points can be connected via fieldbuses(such as Modbus RTU/TCP and Profibus DP)or dedicated expansion modules.
Communication Protocols:
The built-in Ethernet interface(10/100 Mbps)supports standard protocols such as Modbus TCP and OPC DA/UA,enabling communication with host computers or SCADA systems.
An optional serial communication module(RS485/RS232)provides compatibility with legacy equipment.
