Description
The PC-E984-255 is a Compact 984 programmable logic controller CPU module manufactured by Schneider Electric under the Modicon brand. Equipped with 16k words of logic memory, 42k words of extended register memory, and a logic processing scan time of 2.5 ms per 1,000 instructions, the processor is designed for localized machine control and distributed automation. It integrates onboard network interfaces, including one Modbus serial communication port and one Modbus Plus peer-to-peer network port.
Onboard Interfaces and Data Preservation
The CPU features an integrated Modbus Plus interface, allowing direct peer-to-peer high-speed deterministic communication across distributed controller networks without requiring an external co-processor. Program storage and system overhead registers rely on internal RAM backed by a lithium battery, while a hardware memory-protect switch prevents accidental overwrites. The unit also includes an auxiliary slot supporting optional 8-byte or 32-byte EEPROM cartridges for non-volatile backup.
Programming and Architecture
Operating within the Compact 984 architecture, the PC-E984-255 executes standard Modicon 984 ladder logic programs developed via Modsoft or ProWORX software packages. The module directly mounts to A120-series base plates to handle local and expansion I/O point traffic.

Frequently Asked Questions
Q: How does the PC-E984-255 differ from the PC-E984-251 model?
A: The PC-E984-251 provides two standard RS-232 Modbus serial ports, whereas the PC-E984-255 includes one Modbus RS-232 port and adds an onboard Modbus Plus peer-to-peer networking port.
Q: How is the user program protected against power loss or unauthorized modification?
A: Program registers and logic are sustained by an internal lithium battery. Hardware security is enforced via a physical memory-protect switch, and additional non-volatile backup can be added using an optional EEPROM cartridge.
