NOTES
• To connect the unit you require a Host Link Unit at the PLC end. This unit must support at least the
following command codes:
“RR“,“RH,“RD“,“WR“,“WH“,“WD“ and “SC“
• These command codes are all available in command level 1 and so no special settings are required.
Addressing registers (HR, IR, DM) that are not available will initiate communication errors!
• In order to establish active communication the station number setting on the Host Link Unit must match
the addressed station.
• The physical interface of the ZB4-601/609-IF1 must be configured for RS 422 (not MP) and the
parameters on the Host Link Unit must be set as specified.
• IMPORTANT: The Link Type Selector on the Host Link Unit must be set for Multiple Link.
• During active communication the RCV and XMT LEDs on the Host Link Unit will flicker. If only the RCV
LED flashes (very shortly), this means that the station numbers are not matching or the Link Type
Selector is set for Single Link.
• The bus terminating resistors on the first and last units must be activated. If only two units are linked, then
the resistors of both units must be switched on.
• Fit the screen on the plug connector housing of the ZB4-601/609-IF1. Refer to Omron specifications for
how to fit the screen on the PLC.
