1 Port Programmable DeviceNet Master Interface
I-8124W
The I-8124W can represent an economic solution of DeviceNet application and be a DeviceNet
master device on the DeviceNet network. I-8124W supports Group 2 and UCMM functions
simultaneously. It can be installed in ViewPAC or WP-8000 series PAC. It is popularly applied in the
industrial automation, building automation, vehicle, and embedded control network. There is a
complete DeviceNet protocol firmware in the I-8124W. The users can easily access the slave device
via I-8124W in the ViewPAC and WP-8000 and need not to deal with the complex DeviceNet
protocol. The uses can use as easy as “Read/Write” functions to access slave I/O data.
