EC: Productivity3000 P3-SCM serial communications module
The Productivity3000 programmable automation controller (PAC) is a compact logic controller that combines the features and capabilities of a PC-based control system with that of a typical programmable logic controller (PLC). The P3-SCM is a Productivity3000 4-port serial communications module with three RS-232 (RJ12) half or full duplex ports; Port 4 is selectable between an RS-232C (RJ12) or an RS-485 4-wire terminal block. All ports support Modbus RTU Master/Slave, ASCII In/Out and Custom Protocol up to 38.4K baud rate. Using multiple P3-SCMs (up to 11) in the Productivity3000 provides additional serial ports to connect to many peripherals such as HMI displays (C-more, Micro, ViewMarQ, etc.), drives (GSDrives, SureStep, SureServo, etc.), weight scales, printers and most any Modbus or ASCII device.
