10 / 29 page CJ2M-CPU3 @/-CPU1@/-MD21@ 10 *12.A Serial Option Board is required to use a serial port for the CJ2M-CPU3@ CJ2M CPU Unit. *13.Supported only by the CJ2M-CPU3@. Function Description Communications − Peripheral (USB) Port Peripheral Bus Bus for communications with various kinds of Support Software running on a personal computer. High-speed communications are supported. Serial Port (Option) *12 Application is possible when a Serial Communications Option Board is mounted. Host Link (SYSWAY) Communications Host Link commands or FINS commands placed between Host Link headers and terminators can be sent from a host computer or PT to read/write I/O memory, read/control the operating mode, and perform other operations for PLC. No-protocol Communications I/O instructions for communications ports (such as TXD/RXD instructions) can be used for data transfer with peripheral devices such as bar code readers and printers. NT Link Communications I/O memory in the PLC can be allocated and directly linked to various PT functions, including status control areas, status notification areas, touch switches, lamps, memory tables, and other objects. Peripheral Bus Bus for communications with various kinds of Support Software running on a personal computer. High-speed communications are supported. Serial Gateway This gateway enables receiving and automatically converting FINS to the CompoWay/F. Serial PLC Links Data is exchanged between CPU Units using serial ports without communications programming. PTs set to the 1:N NT Link protocol can be included in the network. EtherNet/IP Port *13 100Base-TX/10Base-T Protocols: TCP/IP, UDP, ARP, ICMP (ping only), BOOTP Applications: FINS, CIP, SNTP, DNS (Client), FTP (Server) CIP Communications Service Tag Data Links Programless cyclic data exchanges with the devices on the EtherNet/IP network. Message Communications Any CIP commands can be received from the devices on the EtherNet/IP network. FINS Communications Service Message Communications Any FINS commands can be transferred with the devices on the EtherNet/IP network. Interrupt Scheduled Interrupts Tasks can be executed at a specified interval (minimum of 0.2 ms, Unit: 0.1 ms). Resetting and restarting with MSKS(690) When MSKS(690) is executed, the internal timer is restarted and the time to first interrupt is set to a fixed value. Reading present value of internal timer with MSKS(690) MSKS(690) can be used to read the time that has elapsed until the schedule interrupt is started or since the previous scheduled interrupt. Power OFF Interrupts A task can be executed when CPU Unit's power turns OFF. I/O Interrupt Tasks A task can be executed when an input signal is input to an Interrupt Input Unit. External Interrupt Tasks A task can be executed when interrupts are requested from a Special I/O Unit or a CPU Bus Unit. Clock Clock Function Clock data is stored in memory. Accuracy (Accuracy depends on the temperature.) Ambient temperature of 55 °C: −3.5 to +0.5 min error per month Ambient temperature of 25 °C: −1.5 to +1.5 min error per month Ambient temperature of 0 °C: −3 to +1 min error per month Operation Start Time Storage The time when operating mode was last changed to RUN mode or MONITOR mode is stored. Operation Stop Time Storage The last time a fatal error occurred or the last time the operating mode was changed to PROGRAM mode is stored. Startup Time Storage The time when the power was turned ON is stored. Power Interruption Time Storage The time when the power is turned OFF is stored. Total Power ON Time Calculation The total time that the PLC has been ON is stored in increments of 10 hours. Power ON Clock Data Storage A history of the times when the power was turned ON is stored. User Program Overwritten Time Storage The time that the user program was last overwritten is stored. Parameter Date Storage The time when the Parameter Area was overwritten is stored. Power Supply Management Memory Protection Holding Area data, DM Area data, EM Area data, Counter Completion Flags, and counter present values are held even when power is turned OFF. CIO Area, Work Area, some Auxiliary Area data, and Timer Completion Flags, timer present values, index registers, and data registers can be protected by turning ON the IOM Hold Bit in the Auxiliary Area, and by also setting the IOM Hold Bit to “Hold” in the PLC Setup. Power OFF Detection Time Setting The detection time for power interruptions can be set. AC power supply: 10 to 25 ms (variable) DC power supply: 2 to 5 ms (CJ1W-PD022) or 2 to 20 ms (CJ1W-PD025) Power OFF Detection Delay Time The detection of power interruptions can be delayed: 0 to 10 ms (Not supported by the CJ1W-PD022.) Number of Power Interruptions Counter The number of times power has been interrupted is counted. |
