![]() ![]() The programming software allows you to perform offline simulations before installing a system.Īn LCD built into the PLC allows faults to be identified using diagnostic codes. The PLC can be programmed using any of six IEC 61131-3 languages. ![]() The interchangeable PLCs are the same size, avoiding the need to change connecting parts or terminal bases when you upgrade. There is a choice of three plug-and-play CPUs, with memory sizes ranging from 64kb to 4MB. These can be used together, or can be integrated independently into existing automation systems. ![]() The AC500 system consists of three products PLCs, I/O modules and HMIs. James Large, product manager for automation components at ABB`s low-voltage products division, says that sales of the AC31 were hindered by the "lack of a coherent support and growth strategy". The new PLC (above) supersedes the earlier AC31 family which has had limited success in the UK since it was launched about a decade ago. Its main targets will be existing users of ABB automation equipment, such as drives and motors in particular, OEMs and systems integrators. ABB has launched a mid-range modular PLC system which, it says, will compete on cost with systems from Mitsubishi, Rockwell and Siemens.ĪBB hopes that the new AC500 system will help it make inroads into a UK market that it estimates is worth £55m. ![]()
