11.2 Overview of FP1 I/O Link Unit
The FP1 I/O Link Unit is the interface unit for exchanging I/O information between programmable
controllers "FP2/FP2SH/FP3/FP10SH" and "FP1".
When the FP1 is connected to the FP2/FP2SH/FP3/FP10SH Remote I/O system [MEWNET-F] via the
I/O link unit, you can exchange I/O information in the serial communication format, using a 2-conductor
cable.
11.2.1 Idea of I/O Link
By connecting the output relays of one programmable controller to the input relays of the other
programmable controller, the output information on one controller can be treated as the input information
on the other controller.Exchanging I/O information like this is called "I/O link".
[Example]
The output relays Y0 to Y7 of "FP1" and the input relays X0 to X7 of "FP2/FP2SH/FP3/FP10SH" are
connected in parallel as shown in the figure below.
Relays Y0 to Y7 correnspond to relays X0 to X7 respectively. If the otuput relay Y3 of "FP1" is turned
ON, the input relay X3 of "FP2/FP2SH/FP3/FP10SH" will be ON.
The following sequence control is available with the I/O link.
The FP1 I/O link unit is the interface unit for exchanging I/O information between programmable
controllers "FP2/FP2SH/FP3/FP10SH" and "FP1" connected with a 2-conductor cable using the
[MEWNET-F].
