The 1771-SDN DeviceNet scanner module acts as an interface between
DeviceNet devices and a PLC-5 controller. The scanner module
communicates with DeviceNet devices over the network to:
• read and write inputs and outputs to and from a device.
• download configuration data to a device.
• monitor operational status of a device.
The scanner module is a single-slot module that resides in a 1771 I/O chassis
that either contains a PLC-5 controller or is on an extended-local I/O link,
remote I/O link, or ControlNet network connected to a PLC-5 controller. The
scanner module has Auto Device Replacement, change of state, cyclic I/O,
pass-through, and Slave mode capability.
The number of PLC DeviceNet scanners that can reside in the same I/O
chassis is limited only by the I/O chassis size, power supply capacity, and
available memory.
