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. I-8124W Architecture DeviceNet Version: Volume I & II, Release 2.0 Programmable Master MAC ID and Baud Rate. Baud Rate: 125K, 250K, 500K bps Support Group 2 and UCMM connection I/O Operating Modes: Poll, Bit-Strobe, Change of State / Cyclic I/O Length: 512 Bytes max (Input/Output) per slave Slave Node : 63 nodes max Support Auto-Search slave device function.
