[3] Data transmission between master PC and slave PC

Providing synchronous transfer gives positive data communication.

[An example of synchronized transfer by OUT instruction]

- 00000 is turned "ON" at the master station side.(OUT 02000 is a self-holding circuit.)
- When 02000 is turned "ON" at the slave station side, OUT 02030 is also turned "ON." This is sent

back to the master station side.
