MODICON AS-B885-002 ASCII BASIC Communication Module

MODICON AS-B885-002 is a high-performance communication module for Modicon 800 / 984 series PLC automation systems. This communication module is an intelligent ASCII/BASIC processor equipped with two RS232/422 serial ports and 64K onboard RAM. The communication module adopts isolated serial transceiver circuit and industrial anti-interference PCB layout. This communication module supports stable continuous operation in packaging, textile, material handling and general industrial automation production lines.

It serves as a core serial processor to run local BASIC programs and exchange ASCII data with printers, barcode scanners, weighing instruments and third-party serial devices. The serial processor processes data independently and exchanges information with the PLC CPU via the backplane bus. This serial processor provides LED status indicators for communication activity and fault diagnosis. The serial processor is fully compatible with Modicon 984 rack-based PLC systems.

The unit delivers dependable asynchronous data exchange for serial instrument integration and custom protocol conversion applications. Accurate asynchronous data exchange offloads communication tasks from the main PLC processor. Stable asynchronous data exchange ensures reliable data transmission between peripheral serial equipment and control system. The asynchronous data exchange of this model meets strict industrial automation standards.
