(c) MC protocol communication (
• External devices such as personal computers and display devices read/write
device data from/to the Built-in Ethernet port QCPU. This enables external
devices to monitor the operation of the CPU module, analyze data, and
manage production.
(d) Time setting function (SNTP client) (
• The time setting function enables automatic time setting for the Built-in
Ethernet port QCPU, resulting in reducing the maintenance cost for time
setting.
• By synchronizing the Built-in Ethernet port QCPU connected via Ethernet,
error occurrence order for each process can be checked and troubleshooting
becomes easy.
• Since time setting can be performed automatically at programmable
controller CPU power ON, the CPU module can start operation with accurate
time data.
(e) File transfer function (FTP) (
• An external device with a FTP client function can read/write files from/to the
Built-in Ethernet port QCPU in units of files, so that data such as in the
program file and/or file register can be transferred easily.
(f) Remote password (
• The Built-in Ethernet port QCPU can prevent unauthorized access from
outside of the system and enhance the security by setting the remote
password.
POINT
New functions of a CPU module may be added depending on the upgrade of the
serial number of the CPU module or the function version of GX Developer.
For the list of functions have been added with the upgrade of the Universal model
QCPU, refer to Appendix 4.5.
