Controller co-ordinates up to four robots
The IRC5 is the fifth generation robot controller from ABB and is claimed as the biggest technological step forward since the introduction of the first generation S1 in 1974.
Easy to use interface for any automation project
The new SCADA Portal from ABB is an easy-to-use graphical interface for controlling remote processes from small, standalone applications to five clients and up to 10,000 I/O per server
They have been successfully used as a way to quickly develop demonstration units used in training classes.
The simulators are also an effective way for programmers to debug and troubleshoot programs on the actual PLC equipment.
The simulators come in two different configurations.
The first models mount directly on the terminal strip of the PLC eliminating the need for wiring.
This provides a quick way to connect the simulator while removing the need for a lot of wiring.
Another simulator configuration is DIN rail mountable and requires wiring into the PLC.
Digital simulators consist of a series of switches that directly correspond to the digital inputs on the PLC card.
Toggling the switches forces the PLC input on or off.
There are eight digital inputs per module.
The switches have a 24V DC rating and are rated for 20,000 cycles.
analogue simulators have a row of small knobs that control the individual analogue channels on the PLC.
Each simulator module can control four analogue channels.
The adjustment range is from 0-10V.
In the past this type of simulation has been done with large expensive panels.
These PLCdev simulators now make simulation inexpensive, compact and modular.
