Model Interpretation

B885 = Intelligent Programmable Communication Module Series; 001 = Single Serial Port ASCII BASIC Standard Version, distinction 002 Dual Serial Ports, 100 Motion Control Derived Model, with an independent BASIC Interpretation Operating Kernel Built-In. Technical Specifications

Communication interface: 1 isolated RS232/RS422/RS485 software switchable serial port, baud rate adjustable from 300 to 19200 bps, data bits 5 to 8, parity / odd / even, stop bits 1/2 programmable.

Program storage: On-board EEPROM stores Basic user program, program data not lost during power failure, each module occupies 4 PLC register addresses for data interaction.

Backplane power consumption: 5VDC @ 380mA, single slot rack installation position.

Dimensions: 58 (W) × 267 (H) × 216 (D) mm, net weight 1.4kg

Environmental specifications: Operating temperature 0~60℃, storage temperature -40~85℃, humidity < 80% RH without condensation, IP20 cabinet built-in installation.

Interface and matching base

Matching dedicated wiring base AS-8535-000, compatible with B883 series and B884-002 bases, cannot use B883-200/201 temperature measurement dedicated base.

Core functions

Built-in dedicated BASIC programming language, module executes receiving and sending, data parsing, conversion, protocol conversion locally independently, does not occupy PLC scanning cycle; serial port connects weighing instruments, temperature control meters, flow meters, barcode machines and other devices with ASCII serial port; serial port data automatically and bidirectionally interacts with PLC registers; panel operation / fault indicator lights, hardware alarm for program errors; supports custom communication handshake, data packet division, abnormal retransmission logic. Applicable scenarios

Centralized serial port collection of chemical instrument data, uploading of instrument data from plastic extrusion machines, networking of temperature control instruments in heat treatment furnaces, integrating barcode scanning data from assembly lines, and connecting to the old weighing system via Modicon PLC.

Operation and Maintenance

Insert directly into the standard I/O slots of Modicon 800; in case of communication abnormalities, first check the serial port wiring specifications and baud rate parameters; if the program is lost, re-download the Basic source code through the serial port; the B883 temperature/counter and B884-PID series of special IO modules can be installed on the same rack and mixed.
