For the differences in setting due to the link unit or PLC type, see the next subsection “Setting the PLC”. 1. In [[Comm settings-1]], set the following data. • Match the baud rate, data length, parity and stop bit length of the BL-600 to those of the PLC. • Disable the RTS/CTS protocol. • Disable the multi-drop link. 2. In [[Comm settings-2]], set the following data. • Type of the PLC When using the KV-L2* in “Display interface mode”, set “SYSMAC-C” in the BL-600 settings. • PLC trigger input area • DM head address • PLC unit No./station No. • Set whether or not the final register is used. 8.2.2 Setting the PLC Set the PLC or link unit as follows: ■ Setting MELSEC-A Series 1. Set the RS-232C communication parameters (baud rate, data length, parity and stop bit length) according to the BL-600’s settings. 8 2. Set the station number according to the BL-600’s setting. 3. Set the mode to “Protocol Type 4 ”. * Only for the AJ71QC24, set the mode to “Special protocol”, “ASCII”, and “Type4”. 4. Set the main channel to either “RS-232C” or “RS-422A”. 5. Set “Checksum” to “Enable”. 6. Set “Write during running” to “Enable”. 7. Set “Selecting computer link/multi-drop” to “Computer link” (for the AJ71UC24 only). 132
