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)

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.

Counters using the addition operator. The current value is equal to the set value, the counter, contact is connected. While in the OUT port c command is executed, when counter coil are connected or disconnected, the current values are updated and perform contact ON/OFF operations. Counter values are reset, RST-c can be used to perform.

Interrupt counter is to interrupt the counter counts the number of occurrences. When an interrupt when the conditions are met to update the current value of the counter. Interrupt counter starting counter number available parameter set (uses 256 counting from the first counter). Interrupt counters count is not in place. Use it for control, MOV … Continue reading Mitsubishi Q Series PLC interrupt counter

Data register is a CPU module for working with numerical data in a soft component. 16-bit data can be saved in the data register ( -32768~32767 or 0H~FFFFH), for 2 points (for example, D0 and D1) can store 32-bit data ( -2147483648~2147483647 or 0H~FFFFFFFFH).

(1) the link register (w)The link register is linked to the MELSECNET/H network module registers (LW) when the data is refreshed, using soft components in the CPU module. Link register save 16 bit data, 2 32-bit data that can be stored in a row.(2) the link special register (SW)Links to specific registers are saved MELSECNET/H … Continue reading Mitsubishi Q Series PLC link register special register with the link (SW)

Features soft components is a soft element to use when calling a subroutine. Through the use of functional soft component, could decide as a subroutine call software components used by the source. Even if you don't know what other programs called source, you can also use the same subroutine.1) features input (FX): used when data … Continue reading Mitsubishi Q Series PLC features soft elements (FX, and FY, and FD)
