ABB Advant Controller 31 40&50 Series controllers

Binary extensions: XI 16 E1 (16 inputs), XO 08 R1 (8 relay outputs), supporting up to 6 modules.

Simulation extension: XM 06 B5 (4 inputs+2 outputs), XE 08 B5 (8 inputs), supports signals such as current (4-20mA), voltage (± 10V), temperature (Pt100/Pt1000), etc.

Remote integration

Connect remote units (such as ICMK 14 F1/N1) through CS 31 bus to achieve decentralized I/O acquisition and control, suitable for large equipment or long-distance scenarios (such as workshop cross area control).

Support third-party device access, such as ABB ACS series frequency converters (via NCSA-01 interface), high-speed counters (ICSF 08 D1), etc., communicating through CS 31 protocol.

HMI and upper system integration

TC50 monitor: Connected via RS232/RS485, supports 128 page display, parameter modification, alarm prompts, and is compatible with MODBUS protocol.

Programming and Monitoring: Program download and online debugging are achieved through AC31GRAF software (Windows environment), which supports real-time data interaction with PC.

Communication optimization and diagnosis

Redundancy and reliability

The CS 31 bus supports media redundancy (dual cables) and bus redundancy (dual master stations), and achieves automatic fault switching through NCBR amplifiers to reduce the risk of communication interruption.

Communication timeout detection: The master station identifies faulty slave stations through CRC checksum timeout mechanism (default 250ms), triggers alarms, and records error codes.

diagnostic function

Error classification: Divided into 4 levels (fatal error, serious error, light error, warning), the specific cause (such as bus disconnection, address conflict) is displayed through the ERR indicator light and software (AC31GRAF) of the central unit.

Communication status monitoring: Real time monitoring of communication health through variables IW 62.15 (CS 31 bus status) and MW 255. x (MODBUS watchdog).
