The Micro800 programs with a software package known as Connected Component WorkBench (CCW). ©Rockwell Automation Downloading Programming Software Wiring the Serial Communication ModuleĬonnect the RJ45 plug on your drive to your Micro800 controller’s isolated serial port by using a two-wire, twisted-pair shielded cable (Belden 3105A, recommended). The serial plug-in module (2080-SERIALISOL) does not require a connector it has a terminal block and the networking cable (RS485) will directly into the plug-in module. AK-U0-RJ45-TB2P drive terminals come with six terminals and two resistors in each package for easy connection to the network. The baud rate helps with noise immunity versus higher-speed networks.Įach drive will need a two-position terminal with an RJ45 connector on one end of the device.

The physical wiring is a very simple design called “daisy chaining,” place each wire on top of each other, ground the shields to drain any noise that may get on the network. If you are not placing many devices on a network, this might be an excellent alternative to a CompactLogix system. The advent of the UDFB (user defined function block) takes many steps out of programming. The Micro830 is more suitable for the cost to perform well on slow serial networks such as Modbus RTUĮtherNet/IP is an extremely fast network compared to Modbus RTU, but don’t overlook Modbus and Micro800 on low-budget, high-priority jobs.If the Micro800 can do Modbus RTU, the CompactLogix and the ControlLogix can accomplish the same networking scheme.End resistors of 120 ohms should be placed at the physical end of the network.If you are considering this solution, here are some factors to keep in mind: With a 19.2K baud rate, if your system requirements are minimal, a Micro830 with a serial plug-in module may make sense for you. ModBus RTU is a lower-cost, more code-intensive solution.
