1785 PLC-5 Programmable Controller: 

The PLC-5 programmable controller brings together current and future systems through networks such as EtherNet/IP, ControlNet and DeviceNet, and offers connectivity among SLC 500, ControlLogix, and MicroLogix controllers.  Since they include embedded network connections, PLC-5 controllers enable your control architecture to be flexible enough to include cost-effective connections to a wide range of devices.

A PLC-5/1771 control system includes a programmable controller and I/O modules in a single 1771 chassis with a power supply.

Use specific PLC-5 controllers with network connections and install multiple communication modules into the PLC-5 backplane to route control and information data between the different networks. The networking capabilities, led by EtherNet/IP, ControlNet, and DeviceNet networks, allow information exchange between a range of devices and computing platforms and operating systems. PLC-5 controllers come with different network connections. Choose the network that best meets your needs.
