Monitoring the cycle time Monitors the cycle time. CPU Unit built-in functions Inputs High-speed counter inputs High-speed pulse inputs High-speed pulses from devices such as a rotary encoder are counted. The counted values are stored in the Auxiliary Area. Interrupt tasks can be executed when target is reached or by range comparison. Input pulse frequency measurement The frequency of pulses input by the PRV instruction is measured. Interrupt inputs Relevant interrupt tasks are executed during the cycle when the CPU Unit built-in inputs turn ON or turn OFF. Quick-response inputs Inputs can be read without being affected by cycle time. Use the quick-response inputs to read signals shorter than the cycle time. Normal inputs I/O refreshing Cyclic refreshing The CPU Unit’s built-in I/O are cyclically refreshed. Immediate refreshing I/O refreshing by immediate refreshing instructions Input response times Input constants can be set for Basic I/O Units. The response time can be increased to reduce the effects of chattering and noise at input contacts. The response time can be decreased to enable detecting shorter input pulses. Outputs Pulse outputs (Models with transistor outputs only) Pulse control A pulse signal is output and positioning or speed control is performed with a servo driver that accepts a pulse input. Continuous mode for speed control or independent mode for position control can be used. There are functions for changing to positioning during speed control and for changing the target value during positioning. Origin positioning Origin searches and origin returns PWM outputs (Models with transistor outputs only) Pulses for which the duty ratio (ratio between ON time and OFF time during one pulse cycle) can be set are output. Normal outputs Load OFF function All of the outputs on the CPU Unit’s I/O can be turned OFF when an error occurs in RUN or MONITOR mode. Built-in analog Analog input Convert analog signal into digital value range from 0 to 6,000. Analog output Convert digital value range from 0 to 6,000 into analog signal. Expansion I/O Units and Expansion Units Functions supported by both Expansion I/O Unit and Expansion Unit I/O refreshing Cyclic refreshing The Expansion I/O Units and Expansion Units are cyclically refreshed. Refreshing by IORF I/O refreshing by IORF instruction Load OFF function All of the outputs on Expansion I/O Units and Expansion Units are turned OFF (0000 hex) when an error occurs in RUN or MONITOR mode. Expansion I/O Units Input response times The response time can be increased to reduce the effects of chattering and noise at input contacts. The response time can be decreased to enable detecting shorter input pulses. Expansion Units Unit error detection Errors in Expansion Units are detected. The CPU Unit is notified that the Expansion Unit stopped due to an error. Memory management functions Holding I/O memory when changing operating modes The status of I/O memory can be held when the operating mode is changed. The forced-set/reset status can be held when the operating mode is changed. Automatic backup to the backup memory (built-in EEPROM) Automatic backup of ladder programs and parameter area to the backup memory (built-in EEPROM) Communic ations Peripheral USB port Peripheral bus (toolbus) For communications with programming device (CX-Programmer). Serial port (N/NA-type only) -- Host Link (SYSWAY) communications Host Link commands can be sent from a PT or a computer to read/write I/O memory, and perform other operations for PLC. No-protocol communications I/O instructions for communications ports (TXD/RXD instructions) can be used for data transfer with peripheral devices such as bar code readers. 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. Serial PLC Links Up to ten words per Unit can be shared by up to nine CPU Units, including one Polling Unit and eight Polled Units. Note: Programmable Terminal (PT) cannot be connected. Modbus-RTU Easy Master function Modbus-RTU commands are sent by the Modbus-RTU Master function. Modbus slaves, such as inverters, can be easily controlled with serial communications. Interrupt Scheduled interrupts Tasks can be executed at a specified interval (1.0 ms min., Unit: 0.1 ms). Interrupt inputs Interrupt tasks are processed when the built-in input turns ON or OFF. High-speed counter interrupts This function counts input pulses with the CPU Unit’s built-in high-speed counter and executes an interrupt task when the count reaches the preset value or falls within a preset range (target value or zone comparison). |
