7.2.21 Serial Communications
Use {–MENU– / SERIAL COMM} to configure the serial communications port for operation using the
MODBUS protocol (refer to the Pulsanet Specification section at the back of this manual for further
information).
By using the serial communications port you can communicate digitally with your DLCM. This allows
a PC/PLC or another DLC or DLCM to send and receive exact values. This eliminates inaccuracies
typically associated with analog signal conversion.
In order for two or more devices to communicate using serial communications they must:
− Be electrically connected (refer to Section 5.3: Electrical Wiring).
− Enabled.
− Speak the same language (protocol).
− Speak at the same speed (baud rate).
− Use the same error detection protocol.
− Have unique addressing in the network..
− Have only one master on a given network.
The {SERIAL COMM} menu allows the setting of these communication parameters.
