Modicon Modbus Plus Option Card
The EZTouch Panel Models EZ-T10C-FSM, and EZ-T15C-FSM have the Modbus
Plus Option Card installed. A special connector is attached to these option
boards and is accessible from the bottom of the unit.
The bottom of the plastic back cover has a section that has been removed to
allow access to the Modbus connector (9-pin Female D-SUB) that extends over
the edge of the board. Two types of connectors are available from Modicon for
connecting devices to the network. Each inline drop requires a line connector,
Modicon part number AS-MBKT-085. This part number contains one connec-
tor. The drops at the two ends of the cable, each require a terminating connec-
tor, Modicon part number AS-MBKT-185. This contains two connectors.
The Modbus Plus node address can be set using the first six positions of the
DIP switches located at the top of the option board as shown in the diagram
below. When the board is seated in the panel, setting the DIP Switch in the UP
position is the ON position. There are three Status LEDs on the Modbus Plus
option card: MBP, TXD, and RXD. The TXD and RXD LEDs indicate the board
is transmitting or receiving data. The MPB LED (leftmost LED) indicates Modbus
Plus status.
