The serial communication module CMM201-0201 provides interfaces for communication devices such as variable frequency drives, chiller unit cluster control cabinets, intelligent low-voltage systems, lighting, escalators, and fire protection equipment. It features two RE485 interfaces and one Ethernet interface.
Metro Environment and Equipment Monitoring System (BAS) Solution
① The host unit features an NA400 hot-standby redundant CPU, providing CPU redundancy, network redundancy, power redundancy, and DP bus redundancy functions.
② The remote I/O system is implemented using the NA200 series I/O acquisition modules and the CMM201-0203 dual DP-interface Profibus DP slave module.
③ The CMM201-0201 serial communication module provides interfaces for communication devices such as variable frequency drives, chiller unit cluster control cabinets, intelligent low-voltage systems, lighting, escalators, and fire protection equipment. It features two RE485 interfaces and one Ethernet interface.
④ CMM401-0205 Dual Ethernet Interface Network Communication Module, responsible for communicating with the Integrated Monitoring System and meeting the required interface specifications.
Subway Platform Screen Door Centralized Control System Solution
① The control system consists of a main rack and an expansion rack. The main rack is equipped with a hot-standby redundant power module (which can operate on a single power supply), dual CPUs, and dual Profibus DP master communication modules.
② Install the I/O modules in the expansion rack, and connect the main rack to the expansion rack using a dedicated bus cable.
③ Each CPU integrates an Ethernet interface (Modbus TCP) with a dedicated IP address, responsible for communicating with the integrated monitoring system.
④ Dual Profibus DP communication interface modules, each communicating with the upstream and downstream door control units (DCUs), enabling both bus redundancy and single-bus configurations.
