Description
Allows the programming and monitoring using the engineering tool, and
monitoring and testing programmable controller from the GOT with Ethernet
connection.
Reads/writes the buffer memory, devices, and others from the external
device to an SLMP-compatible device connected in the same network as
the Ethernet-equipped module. Read/write can also be executed to a CPU
module device.
Allows the communication processing only with the program of the start
instruction when the protocol data for communication with the external
device is registered using the engineering tool. The protocol required for
communication with the external device (such as temperature controller and
barcode reader) can be set easily using the engineering tool's
communication protocol support function.
Exchanges arbitrary data with an external device connected by Ethernet
over TCP/IP or UDP/IP using dedicated instructions.
Exchanges arbitrary data between the CPU module and external device
using the fixed buffer of the RJ71EN71 and the RnENCPU (network part).
Reads/writes data from multiple external devices to the random access
buffer of the RJ71EN71 and the RnENCPU (network part).
Allows the MODBUS/TCP-compatible device connected in the same
network as the RJ71EN71 and the RnENCPU (network part) to read/write
the buffer memory or devices from/to the RJ71EN71 and the RnENCPU
(network part).
Reads/writes data from/to other station CPU modules on other networks via
Ethernet using the link dedicated instructions.
Monitors and diagnoses the CPU module via network using a Web browser.
Reads/writes data in file units using the dedicated FTP commands from an
external device.
Enables the CPU module, as an FTP client, to transfer files to an FTP
server connected over Ethernet by using the file transfer function
instructions.
Automatically performs time setting of the CPU module by collecting clock
data from the time information server (SNTP server) on the LAN.
Identifies the IP address of the access source to limit access to the
Ethernet-equipped module.
Prevents Illegal access of the CPU module from a remote location.
Allows data communications between specified devices at the specified
timing just by doing simple settings from an engineering tool.
Changes the CPU module's IP address without changing the parameter
settings.
Checks the connection state, protocol state, and line state using the
engineering tool.
Detects devices supporting iQSS which are connected to the CPU module
(built-in Ethernet port part), and automatically displays them on "List of
devices" and "Device map area" using an engineering tool.
