Q Series PLC also has analogue modules, temperature control module, high-speed counter module, serial communication module, module, ID interface modules, Windows high performance such as CPU module module, greatly enriched the PLC control functions.

Input is done by button, switch, limit switch, digital switches and other peripherals to the PLC transmits commands and data. Enter a refreshing entry and direct access input. Refresh Refreshes when the input is at the END, read from all input devices together. In a sequential program by x-direct access input refers to each touch … Continue reading Mitsubishi Q Series PLC inputs (x)

Output refers to the procedure of control results to the outside coil, such as lights, digital display output. Output refresh, and direct access to the output. Flushes the output is at the END when refreshed on total output module output together, in sequence control program using y-; direct access to the output means each coil … Continue reading Mitsubishi Q Series PLC output (Y)

Internal relays inside the CPU module is not latching (that is, non-power outages keep) a kind of auxiliary relays. Power on or when CPU module reset and clear the latch when it is set to OFF. Program results to an external output, the output (Y).

Signal alarm is used to detect equipment malfunction or failure of a convenient internal relays. Signal when the alarm is ON, special relay (SM62) ON, special register (SD62~SD79) will signal the number of save is set to ON and the serial number. Fault detection using signal alarm program, when a special relay (SM62) was ON … Continue reading Mitsubishi Q Series PLC signal alarm (F)

Latching relays inside the CPU module used is a latch can be carried out (that is, power outages remain) the auxiliary relay. The power is switched on, even if the CPU module reset, logical result can also be maintained. If latch removal operation, it can be set to OFF, program results to an external output, … Continue reading Mitsubishi Q Series PLC latching relays (L)

Edge can only be used when the contacts of the relay, in indexing structured programs, jump (OFF → ON) appears to perform operations.

Link to relay (b) is a link MELSECHET/H network module module relay (LB) Refresh on the CPU module, or flush data to the MELSECHET/H network module in the CPU module and other modules link to relay (LB), the CPU module uses software components (relays). LB and b set to refresh refresh parameters of the ranges … Continue reading Mitsubishi Q Series PLC link relay (b)

Operation with the addition of the timer. Coil when the timer is switched on, starting today, the current value reaches or exceeds the set value, timing, contacts are closed. Timer, low speed, low accumulation, high accumulation of four, specifying the method varies. Cumulative timer even when the coil is OFF, can keep the current value … Continue reading Mitsubishi Q Series PLC timer (t)

(1) links to special relays (SB)Used to monitor MELSECHET/H network communication status and the internal relays of the exception.(2) step relay (s)Step relay (s) is used on the SFC's soft components.
