Using network module
Using remote I/O slave module
PCs which can use
1①Data link/computer link function
This function enables to send and receive ON/OFF signals and numeric data between modules on a network (satellite net) which is connected PCs and personal computers having network module
If remote I/O slave module
·In the remote I/O function, the remote I/O can choose either of synchronous or asynchronous for sending and receiving data with slave stations.
Synchronous type: Slave station scans input/output operation one time for each operation of the PC.
Asynchronous type: When PC's operation time is longer than data transfer required time of the remote I/O, the slave station scans input/output operation one time for each operation of the PC. When PC's operation time is shorter than the data transfer required time of the remote I/O, the slave station operate input and output one time for several operation of the PC.③Remote programming/remote monitor function
By constructing a satellite system using the
·These remote programming and remote monitor functions are also available beyond one hierarchical layer difference (satellite net ←→ satellite net, satellite net ←→
