SSCNETIII/H compatible and SSCNETIII compatible servo amplifiers can be used together.(The communications speed when SSCNETIII compatible products are used together in the same system: 150 Mbps full duplex).Long distance wiring is possible up to 3200 m (10498.69 ft.) per system (maximum of 100 m (328.08 ft.) between stations x control axes up to 32 axes), suitable for large-scale systems.Synchronous communications are achieved with SSCNETIII/H, offering technical advantages for machines that require deterministic control.
System response is dramatically improved.Communications speed is increased to 150 Mbps full duplex (equivalent to 300 Mbps half duplex), three times faster than the conventional speed.M8039 – If its coil is energized, the PLC will operate according to the scan time specified in D8039.High-speed Synchronous Network SSCNETIII/H M8034 – If the coil is energized, the output of the PLC is completely disabled. M8033 – If its coil is energized, the output image memory and data register contents are maintained when the PLC is stopped. The PLC performs a specific action after the coil is driven by the user program. M8003 – Initialize pulse normally closed contact, OFF one scan cycle when PLC is running. M8002 – Initialize pulse normally open contact, ON one scan cycle when PLC is running. M8001-Operation monitors normally closed contacts, and the PLC keeps OFF when it is running. M8000-Operation monitors normally open contacts, and the PLC is always ON when it is running. If you want to know more, you need a programming manual. There are other special auxiliary relays, which are commonly used. It is a time pulse with periods of 10ms, 100ms, 1000ms (one second), m8020, m8021, m8022, which are standard real bits, representing benefits, zeros, and endings. When plc is just started, it closes a cycle, but 8001 is normally closed, 8002 is normally open, m8011, 8012, 8013.
m8001 and m8002 are initialization pulses. PLC M8000-M8990 is a special internal relay of Mitsubishi PLC.
