Introduction
The PROFI-8455-G Remote I/O Unit is specially designed for the slave device of PROFIBUS DP protocol. It supports up to 4 slots for ICPDAS I-8k series, I-87k Low Profile series, and I-87k High Profiles series I/O modules. In addition, we also provide hot-swap function for I-87k High Profiles series I/O modules. To setup network, users can choose and configure I/O modules by using the GSD file without any other setting tools.
Features
- Protocol & Hierarchy : DP-V0 Slave
- Transmission Rate Setting : detected automatically
- Address Setting : 0~126 set by Rotary switches
- I/O modules Configuration : Configured by GSD file
