Product details

Processor placement in a Modicon M340 rack

The BMXP3420102 is a Modicon M340 processor module that draws its supply from the rack backplane, so no separate 24 VDC feed to the module itself — budget the 90 mA draw in the rack power supply sizing. It hosts two fieldbus personalities: a CANopen master port (M20 DS 301/303-2/405, up to 63 nodes, bit rates from 20 kbit/s to 1 Mbit/s) and a non-isolated serial Modbus port (RS232C or RS485, RTU/ASCII, up to 19.2 kbit/s). The CANopen bus handles up to 64 devices per segment depending on data rate; the Modbus port addresses 0..248 slaves in RTU or ASCII mode. Internal RAM is 4096 kB total (256 kB dedicated to data, 3584 kB for program, constants, and symbols). A supplied memory card (BMXRMS008MP) provides backup of programs, constants, symbols, and data in case of power loss.

Performance and task structure

Executes Boolean logic in 0.12 µs, single-length words in 0.25 µs, and floating-point operations in 1.16 µs. Mixed instruction throughput is 6.4 Kinst/ms at 65 % Boolean + 35 % fixed arithmetic; pure Boolean reaches 8.1 Kinst/ms. Application structure allows one cyclic/periodic master task, one periodic fast task, and up to 64 event tasks. The fast-task overhead is 0.13 ms; the master task overhead is 0.7 ms. Supports up to 256 analogue I/O channels and 4 racks. CANopen motion control is available for independent axis control — relevant if you are coordinating servo or stepper drives over the CANopen bus.

Carries marking for CE, UL, CSA, RCM, EAC, UKCA, China RoHS, and WEEE. Conforms to IEC 61131-2, IEC 61010-2-201, UL 61010-2-201, CSA C22.2 No 61010-2-201, IACS, EN/IEC 61000-6-5 (interface types 1 and 2), and EN/IEC 61850-3 (location G). Ambient operating temperature range is 0…60 °C, with relative humidity 5…95 % without condensation. IP20 protected; protective treatment is TC (conformal coating per class TC). For semiconductor fab or harsh environment use, the coating limits particle shedding and moisture ingress.

Frequently asked questions

What compliance documentation does Schneider provide for the BMXP3420102 (RoHS, UL, IEC)?

The module carries CE, UL, CSA, RCM, EAC, UKCA, China RoHS, and WEEE markings. It conforms to IEC 61131-2, IEC 61010-2-201, UL 61010-2-201, CSA C22.2 No 61010-2-201, IACS, EN/IEC 61000-6-5, and EN/IEC 61850-3.

What supply voltage does the BMXP3420102 need?

The module is powered internally via the rack backplane. It draws 90 mA at 24 VDC from the rack, so no separate power supply wiring is required to the module.
