Perfect for OEMs that need a cost-effective solution with enough functionality for demanding applications.Backlit color TFT LCD display provides excellent color and a wide viewing angle for a clear picture of machine or process.Built-in connectivity includes serial ports, Ethernet, and USB.It is also a research company, investing EUR10 billion in innovation and RD for sustainable development between 2015 and 2025.
A Do-more runs at about 800 for the base model, which is just about the lowest price for this tier of PLC. As programmed intelligence, a controller runs by itself with no need for human interaction, except to receive updated set points or supervisor commands from the SCADA system or local HMI. Changing priorities or schedules on HVAC equipment, or performing automatic throw-over (ATO) on electrical switchgear are just a few examples. If youve been tasked with determining what control solution is needed for your next application, a control system integrator (CSI) can be an excellent resource. Their priority should be to understand your specific technical and commercial requirements. If a CSI tries to make your application fit in to their PLC solution, then you are not working with a true systems integrator. Knowing how fast you want to go (CPU speed), how many people can it accommodate (number of IO), its reliability (warranty and redundancy options), and if you need to go off-road (environmentconformal coatings) are just a few of the considerations we ask you about as we seek to establish your requirements. We are experienced with a multitude of different PLCs brands, each with its own merits. Ultimately, it all boils down to reliability, serviceability, maintainability, cost, and long-term effectiveness. Very cost effective, but not hardened. Why hospitals should use PLC not DDC controllers ). These are just our observations and insights from our 14 years helping customers select the correct PLC for their environment. The engineer who programs the PLC can mix and match between ladder logic, function block diagram, structured text, instruction list, and sequential function chart. Not only does this allow for a broader range of developer backgrounds, but some languages lend themselves to greater efficiency in certain tasks. More efficiency and flexibility boils down to less budget spent in hourly development time. Another great pro to Modicon is that the hardware is hardened for industrial environments. Most models are made to control large and complex machines in dirty environments. Additionally, they have incorporated the EthernetIP standard in their product line to allow for deterministic distributed IO, which is important in mission critical control environments. A typical cost will be a bit higher than average, especially compared to other non-hardened PLCs. They might do this to avoid competition poaching or simply to ensure the device is programmed correctly. However, this proprietary policy makes it very difficult for customer OM techs to fix minor issues, and forces them to schedule out and pay extra for certified Schneider Electric techs or control vendors. In addition, their technical support agents native language might not be English. But it all depends on what equipment youre getting, and in which part of the world its sourced. They arent a great fit for redundancy or for smart instruments, but are a fantastic cost-effective solution for basic analog, discrete, and Modbus communications.
