Description
Backs up latch data such as device data and error history without using a battery.
Writes/reads device data to/from the standard ROM using an instruction.
Reads the model name of a module connected.
Saves the data in a CPU module to an SD memory card when changing the CPU
module.
Controls the clock data of the CPU module.
Prolongs a battery life by limiting the data to be latched to clock data only.
Collects data from the specified device of a CPU module at a specified timing.
Obtains ON and OFF signals via 16 built-in external input devices.
Outputs ON and OFF signals via eight built-in external input devices.
Executes an interrupt program using a built-in external input or output signal as a
trigger.
Catches pulse signals with the ON time shorter than the scan time that the general-
purpose input function cannot catch.
Controls a drive unit by outputting pulses from an external I/O connector.
Counts data such as pulses that are input to the external I/O connectors. Also
outputs ON/OFF data by comparing the counted values and measures the ON-
pulse width of the input pulse.
Connection with a programming tool and GOT using a hub is allowed.
Connection with a programming tool is allowed only by one Ethernet cable.
Device data of the CPU module can be read and written using the MC protocol.
Sends and receives any given data by TCP/UDP to and from devices connected on
Ethernet using a dedicated instruction.
Automatically sets the clock by obtaining a clock data from the clock information
server connected on the LAN.
Reads and writes files to and from a target device using the server of FTP.
Checks a remote password upon request of a connection.
Allows communications via the built-in CC-Link.
