EIMXM is an integrated communication protocol module that conforms to the MODBUS RTU communication protocol format. It is an expansion module specially designed to match the WC, GC, DAC, DSC and other series of products produced by AIRTEK. It is often used as equipment manufactured by third parties. Or for system integration, such as inverters, multi-function meters, two-wire lighting systems, smart sensors and other equipment. EIMXM is manufactured with a 32-bit high-efficiency microprocessor, with independent operation and network communication capabilities. It is mounted under the EIMnet communication network, and can directly convert its own BI/AI/BO/AO/PI software points to the BI/AI/BO/AO/PI points of the upper DDC controller to achieve the same DDC Complete the effectiveness of the control program to ensure the reliability of the independent operation of the control system.
【Features】
- Built-in EIMnet communication interface, following the MODBUS RTU communication format, using RS-485 transmission, the line can extend up to 1,200 meters.
- Built-in RS-232 communication interface, through AD-Linker, with EIMXM exclusive editing program (EIMXM editor) to modify the communication parameters.
- With Address dial switch, the address range can be set from 1 to 24, but each DDC controller only allows one EIMXM module to be connected.
- With communication and equipment status indicator lights, it is convenient for on-site engineers to grasp the system operation status and troubleshooting in time.
- It can be used with AIRTEK WC, GC, DAC, and DSCB microcomputer programmable controllers, which can flexibly allocate points, reduce equipment costs and increase the integrity of the control program.
- The BI/A0/BO/AO software points on the EIM can be directly converted to the BI/A0/BO/AO points on the controller without complicated settings and conversions.
- The maximum number of points that can be converted is BI*32 or AI*32 or BO*16 or AO*16, which is the number of physical hardware points that can be connected to 4 EIM..M. All combinations are acceptable and convenient All kinds of applications, but the excess points will not be able to correspond, so please pay attention to use. And the number of EIM..M corresponding to EIMXM will take up the total number of EIMnet communication interface connections, so you must pay attention to it during application.
- It adopts sliding rail design to save space and easy to install. It adopts pluggable terminal design and has communication and equipment status indicators for easy troubleshooting.
- The reading and writing of analog point data can support multiple non-standard numerical forms such as floating-point numbers, double-precision floating-point numbers, long integers, and BCD codes.
- Each analog read and write command supports one addition/subtraction/multiplication/division operation for numerical offset or magnification adjustment.
