Memory and expansion depend on the CPU version
Firmware1.100 and GX Works3 1.047Z or later support128k program steps and up to384 local I/O points; earlier versions use64k steps and up to256 local I/O. Local and remote I/O together remain within512 points. Memory capacity is distinct from scan time and the number of physical terminals.
Use the built-in ports for engineering and machine communication
Ethernet supports MELSOFT connections, SLMP, socket communication and MODBUS/TCP among the documented functions. The built-in serial interface supports MODBUS RTU and other listed protocols; configure protocol parameters and the terminal resistor for the connected network. Ethernet availability alone does not mean that an EtherNet/IP interface is built in.
Match the field circuit to the suffix
The /D version uses sink input wiring for no-voltage contacts or NPN open-collector devices and sink-type transistor outputs. Its field circuit differs from the /DSS source-output version even when the total I/O count is the same.
Field signal and load limits

- Y4 and subsequent maximum load

- Common group limit
0.8 A per common for8 output points
- Off-state output leakage
≤0.1 mA at30 V DC
- Y0–Y3 on-state drop

- Y4 onward on-state drop
≤1.5 V
Manufacturer transistor output circuits and limits
Hardware manual p.33. Use sink wiring for /D and source wiring for /DSS. Common-group and per-point limits both apply.
Fast I/O is terminal-specific
The high-speed input group is X0–X5, with200 kHz response under the specified pulse conditions. The remaining input groups have lower response frequencies. Y0–Y3 have faster switching characteristics than later outputs; do not apply the fast-channel ratings to every terminal.
Power and physical installation

Budget the complete extension system
The CPU-only wattage does not include the complete extension configuration or external field loads. The CPU’s internal supply capacities are720 mA at5 V and500 mA at24 V; calculate extension consumption and any required extension power supply for the selected modules.
Manufacturer connector-type CPU dimensions
Hardware manual p.38: use the 42.1 mm width row. The32/64/96-point bodies have different widths; leave room for I/O cables and extensions.
Manufacturer simultaneous-I/O derating curve
Hardware manual p.34. Only the lower I/O derating graph applies to these transistor CPUs; the upper relay table describes a different model.
Apply the simultaneous-ON and temperature conditions
Permitted simultaneous input/output ON ratios depend on ambient temperature and whether extension modules are connected. The -20 °C lower endpoint applies to products manufactured from June2016; earlier products have a0 °C lower endpoint. For operation below0 °C, use the manual’s low-temperature precautions. Provide external protective circuits for inductive loads and output short circuits.
