It's rated for IEC 61131-2 and UL 61010-2-201, so it passes into a UL 508A panel without compliance hassle. ## Execution speed and memory Boolean execution at 0.12 µs, single-length words at 0.25 µs, floating point at 1.16 µs. Internal RAM totals 4096 kB (3584 kB for program/constants, 256 kB for data). Supports up to 4 racks and 256 analog I/O. One fast task at 0.13 ms overhead handles time-critical loops. ## Connectivity: CANopen, Modbus, serial Integrated CANopen master on a SUB-D 9 port runs at 20 kbit/s to 1 Mbit/s, managing up to 63 slaves. Two serial RJ45 ports handle Modbus RTU/ASCII and character mode on RS232 or RS485, with non-isolated links up to 10 m or isolated up to 1000 m. A USB port at 12 Mbit/s is available for programming.","metaTitle":"Schneider BMXP3420102CL Modicon M340 Processor, CANopen","metaDescription":"BMXP3420102CL Modicon M340 processor module, active lifecycle, internal power via rack, 90 mA @ 24 V DC, CANopen master, CE UL CSA.
