Physically adding a MotiFlex e100 drive to a Modbus/TCP network

The diagram below indicates the pin-out of the Modbus/TCP connector on the edge of the

Modbus/TCP Fieldbus Option card (remember this card MUST be plugged into slot 1 of the

MotiFlex drive):

A ‘crossover’ CAT5e (screened) Ethernet cable should be used to connect the Fieldbus Option to

the Modbus/TCP network.

Once the drive has been physically connected to the network it is ready for communication with

the Modbus/TCP client (e.g. PLC). As mentioned previously, the default drive’s Modbus/TCP

address is 0.0.0.2, which can be changed using the Connectivity Wizard in Workbench.

Refer to MotiFlex Fieldbus Option Card Installation Manual MN1954 for full details on the physical

installation of the option card/module including information about the status LEDs on the card.

Testing Read and Write Data

For the purposes of this Application Note we have used a PC based Modbus/TCP client (a demo

application from Automated Solutions called MiniHMI that illustrates the use of their Modbus/TCP

ActiveX control). See http://www.automatedsolutions.com for further details on their range of

controls. The Modbus/TCP ActiveX and MiniHMI application is available to trial free for 30 days.

The communication parameters for the TCP connection were set as follows:

1 2 ... 6 7 8 9 10 11 12 13 14 15 16 ... 21 22
