Interface
93 RS-485 Communication Interface (Option 5)
6.6 RS-485 Communication Interface (Option 5)
● One to one connection
- Use twisted pair cables for connection. (Noise margin will be expanded.)
However, parallel 2-core cables may be used for short-distance connection.
- Install 100 - 200Ωlevel terminal resistors on the receiving side.
- The terminal SG is a grand terminal used on the circuit for protecting the circuit.
When the main body of F701 and the device connected to F701 are grounded by D type ground, there
is usually no need to use the terminal SG.
However, confirm the specifications of the devise connected before connecting the terminal SG,
when it is necessary to connect it according to the situation of the site.
● One to multiple connection
•How to communicate
1. Set the ID number for each F701(ID ≠ 0000).
2. Send Start command including ID number.
3. One F701 specified by master is now open to communication.
4. Communication commands are RS-232C format.
5. Send Stop command including ID number.
＊ Do not use “0000” as an ID number in a system with multiple F701’s, Communication is opened at
start up with ID number “0000”.
