Communication driver
This is one type of software (OS) for communicating with the PLC.
There is a dedicated communication driver for each communication format (bus connection,
direct CPU connection, etc.), so always install it on the GOT with the OS installation function.
Counter (C)
This is a device that counts how many times the input came ON and switches the contact ON
when the set value is reached.
To clear a counter value, it is necessary to reset the counter with a reset command.
Cyclic communication
This is a function for data communication between stations on the same network with
MELSEC.
This function uses the link relay (B), link register (W), link input (X), and link output (Y) devices.
A GOT directly connected to MELSECNET can use B and W as its own station devices.
D
Data register (D)
This is a PLC register for storing numbers. It is also called a D register.
A data register can handle 16-bit or 32-bit data.
With some PLC types, the data registers can handle not only integers, but real numbers as
well.
The GOT has dedicated GD registers.
Default value
This is the initial value.
Device
This is the general name for memory in the PLC CPU.
There are various devices, such as input (X), output (Y), and data register (D), for various
applications.
Display conditions (write conditions)
Operating (displaying or writing) only when the set conditions are met.
There are the following eight types of conditions.
• Ordinary: Always display.
• Rising: Only display when the specified device comes ON.
• Falling: Only display when the specified device comes ON.
• While ON: Always display while the specified device is ON.
• While OFF: Always display while the specified device is OFF.
• Sampling: Display with the specified cycle unit (1-3600 seconds).
• Cycle during ON: For each specified cycle (1-3600 seconds), always display if the
specified device is ON.
• Cycle during OFF: For each specified cycle (1-3600 seconds), always display if the
specified device is OFF.
