11 MODBUS COMMUNICATIONS
Modbus is an application layer messaging protocol used for client/server communication and is implemented
according to specifications
provided by Modbus Organization ( http://www.modbus.org/specs.php
11.1. TCP/IP Modbus — Optional
Modbus communications over TCP/IP is optional and requires configuration using the SENS Setup Utility
or the keypad. To adjust settings using the keypad, ensure the access level is set to allow adjustments.
Adjust IP address as desired. It may take up to 10 seconds for the network setting changes to apply. A
TCP/IP address of 0.0.0.0 implies DHCP (Dynamic) addressing. Adjust the Gateway and Subnet Mask
values as required. The displayed Hardware Address is the MAC address corresponding to the Ethernet
interface. The MAC address is also shown on the label on the inside of the field wiring cover. This value
is not adjustable. Configure Modbus slave address and enable/disable Modbus write access as desired.
See section
6.8 for connection information.
