Description
Specifies stations reserved for future use. The reserved stations are not
actually connected, but counted as connected stations. The stations are not
detected as faulty stations even though they are not actually connected.
Makes an interrupt request to the CPU module to start the interrupt program if
the interrupt conditions preset using the engineering tool are met. Interrupt
conditions are based on the changes in the link devices (LB, LW, LX) and the
network statuses (SB, SW) checked every link scan or the data reception status
of the channel specified via the RECVS instruction.
Performs communications in a protocol such as FTP and HTTP using the
specified IP address of an Ethernet device, over CC-Link IE Controller Network.
With this function, two networks of CC-Link IE Controller Network and Ethernet
are not required, resulting in reduced wiring cost.
Sets the station numbers of a normal station (own station) using a program.
When there are normal stations with the same program and network
parameters (excluding the station numbers), setting the station numbers using
a program allows project data items other than the station number to be the
same, leading to reduced development work hours. ( MELSEC iQ-R
