According to latest research, Ladder logic continues to be the dominant language for programming PLCs, accounting for more than 81% of the global market, despite the availability of several other languages defined in the IEC 61131-3 standard.
The research from Technavio suggests that Functional Block Diagram (FBD) programming represents just over 11% of the market, with other languages accounting for the remaining 7.24%.
The Global PLC Software Market 2016-2020 report predicts that PLC programming will merge with motion control and robotics programming, and forecasts that the global market for PLC software will be worth $684m by 2020 – representing a CAGR of more than 7% since 2015, when it was worth $485m.
“Traditionally, industrial robots, motion controllers, and PLCs were programmed separately,” explains Technavio automation research analyst, Bharath Kanniappan. “PLCs are programmed in ladder logic, motion controls with their wide range are programmed using a PC library or other proprietary language, and industrial robots are programmed in complex proprietary languages that are difficult for non-technical personnel to understand.
