Modbus Plus Option - Mettler Toledo PANTHER Guide D'installation

Modbus Plus Option

There are two connections for the Modbus Plus Interface.
•
The standard connection for the PANTHER panel-mount terminal is the DE-9 female
connector. Wiring instructions come with the connector. The Modbus Plus network
uses pins 1, 2, and 3 of the DE-9 connector (supplied by Modicon).
•
The PANTHER harsh environment terminal must use a pluggable terminal strip.
When the terminal strip is used, the Modbus Pigtail Cable kit 0900-0320 is
available.
The Modbus Plus pigtail is wired to the PANTHER terminal as follows:
