4.1.6 Interfacing ProtoNode to Siemens LMV3x and Yokogawa Controllers
The LMV3 and Yokogawa profile will be selected in the ProtoNode for installations containing the
Siemens LMV3x and Yokogawa controllers on the boiler. Refer to 4.1.4 above for required LMV3x
controller settings.
Refer to the boiler Installation and Operation Manual and the electrical drawing for specific wiring
requirements. If the Modbus capable Yokogawa is factory installed on the boiler, the Modbus wiring from
the Yokogawa to the boiler terminal blocks will already be installed. If the Modbus capable Yokogawa is
to be installed in the field, the Yokogawa and LMV3x Modbus wiring will need to be installed so that the
devices are in a continuous daisy chain to the ProtoNode.
Terminals 301/304 and 302/305 on the Yokogawa UT32A must be jumped to provide proper operation
even if it is a single device with no daisy chain.
Yokogawa Controller Settings:
• Simultaneously press and hold the “PARA” and left arrow keys for 5 seconds until “Set.M” is
displayed.
• Use the right arrow key to scroll and find the “RS485” menu then press the “SET/Enter” key.
• Set “PSL” to “MBRTU” for Protocol Selection.
• Set “BPS” to “19200” for the baud rate.
• Set “PRI” to “None” for the parity.
• Set “STP” to “1” for the stop bits.
• Set “DLN” to “8” for the data length.
• Set “ADR” to “10 + the LMV Address”. Refer to Figure 8 for LMV and Yokogawa Modbus
addressing.
• If writing the setpoint to the Yokogawa, perform the following:
o Press and hold the “PARA” button for 5 seconds until “OPE.M” is displayed.
o Use the right arrow key to scroll and find the “SPS” menu then press the “SET/Enter” key.
o Scroll down to “SPT” and change this to “OFF” for PV Tracking selection.
