e-9K Modules
e-9K series modules are provided for combining a variety of I/O functions within the AXP-9000
and ALX-9000 programmable automation controllers (PAC). e-9k series is based on a high-speed
bus interface (e-Bus) with speeds up to 2GB/s (e-Bus x4) and 500MB/s(e-Bus x1), and also
supports DMA (Direct memory access) data transfer without the need for a central Processing unit
intervention. e-Bus new generation high-speed bus interface.
ICP DAS fully supports the new generation of high-speed bus interface (e-Bus) in the new
generation flagship controller (AXP/ALX9000). In addition to the maximum speed of up to 2GB/s
(e-Bus x4) and 500MB/s(e-Bus x1), it also supports DMA (Direct memory access) data transmission
without the need for the central processing unit to intervene in processing. Under the burden of
the processor at the same level, DMA is a fast data transfer method, which can provide a large
amount of data transmission and high-speed data comparison of the expansion module, and
improve the working efficiency of the controller.
ICP DAS utilizes the powerful performance of the e-Bus bus interface to fully develop a new
generation of e-9K I/O expansion modules, and fully demonstrate the performance of e-Bus on
the new generation flagship controller (AXP/ALX9000) to provide customers with the high-cost
performance ratio.
