[7] Communication system using the JW-20DN DeviceNet
The JW-20DN conforms to the DeviceNet * and can connect various slave stations. It can share other
facilities inside/outside Japan.
- It employs multi-drop system that can connect between nodes using a single special cable. Therefore,
it offers much wire saving. Branching using a T-branch tap is also available.
- A maximum of four JW-20DN modules (total number of modules including the JW-23LMH) can be
mounted on a single basic rack panel. Shortening communication time or separation of systems by
dividing systems is possible.
- The editing function of scan list facilitates easy allocation of slave station I/O addresses. There is no
need configurator.
