AB 1785-BCM and 1785-BEM Modules for PLC-5 Programmable Controllers

Flexible Configuration and Expansion: The communication ports of 1785-BCM module can be configured as Data Highway Plus or Remote I/O mode to adapt to different network requirements. Users can choose the communication mode flexibly according to the actual application scenarios to meet diversified industrial control needs. For systems using processors such as PLC-5/40, PLC-5/60, etc., the 1785-BEM module can be added to provide backup for the two additional channels of the processor, which enhances the backup function of the system and improves the overall reliability of the system. When upgrading or expanding the production line of an enterprise, the system configuration can be easily adjusted .

Good compatibility: 1785-BCM series B modules are compatible with series A modules, and communication between different series of modules can be achieved by setting switch components SW1 and SW2 to protect users' original investment. When upgrading the system or replacing some components, there is no need to replace the equipment in a large scale, which reduces the cost. The module is compatible with a variety of PLC-5 processors (e.g. PLC-5/15, PLC-5/20, etc.), which is suitable for control systems of different sizes and needs, improving the versatility and applicability of the module .

Convenient Diagnosis and Maintenance: 1785-BCM and 1785-BEM modules are equipped with status indicator lamps, which visually display system operation status and fault information. Users can quickly determine whether the system is running normally through the indicators, and detect faults in time, such as hardware faults, communication faults, etc., so as to facilitate rapid positioning and problem solving. More detailed system status and fault information can be obtained through the relevant bits of the system status word and auxiliary diagnostic/status word, providing powerful support for fault diagnosis and troubleshooting. In complex industrial control systems, it can help technicians accurately determine the cause of the fault and shorten the troubleshooting time .
