Page 11: Df1 Configuration
EGW1-IA3-MB-DF1 – Modbus TCP a DF1 User’s Manual Exemys values, the web service (actually every network connection) will only be available with the newer settings and after the device is reset (software reset takes about three seconds). TCP Keep Alives: This is a common mechanism used to early detect broken TCP connections. If enabled (by setting this parameter to a value bigger than zero) the device will send a frame to those Modbus TCP masters that do not generate requests for a period longer than this value. - Page 12 EGW1-IA3-MB-DF1 – Modbus TCP a DF1 User’s Manual Exemys DF1 Source Address: DF1 frames define Source (SRC) and Destination (DST) addresses, corresponding to the stations that want to exchange data. While these parameters seem to be important, most implementations do not take care of its values. This is because DF1 is commonly used as a point-to-point protocol, where only two stations are connected to the wire.

Page 13: Translation Tables Page
EGW1-IA3-MB-DF1 – Modbus TCP a DF1 User’s Manual Exemys 3.5 Translation Tables page. In these sections, some basic aspects on Modbus TCP and DF1 protocols are outlined. Modbus TCP data are classified into four types, such as defined in Modbus ASCII/RTU. - Page 14 EGW1-IA3-MB-DF1 – Modbus TCP a DF1 User’s Manual Exemys Modbus TCP address boundaries are assigned automatically by the device. For example, if you insert a record into the first position of the N Table, the first Element is mapped to Holding Register 40192, the second Element is mapped to Holding Register 40193 and so on.

Page 15: Operating Modes
EGW1-IA3-MB-DF1 – Modbus TCP a DF1 User’s Manual Exemys 4 Operating modes 4.1 Modbus TCP a DF1 converter Protocol conversion is based on tables that store the mapping between incoming requests (using Modbus TCP protocol) and PLC data areas. Table translation applies for internal memory, but is not used for Inputs/Outputs. - Page 16 EGW1-IA3-MB-DF1 – Modbus TCP a DF1 User’s Manual Exemys Figure 1 - Translation Tables page The page is divided into three sections, the first three are user-configurable, while the last one is fixed. N section lets you add and remove N Files. Each element in an N File is 16-bits wide.

Page 24: Modbus Statistics
EGW1-IA3-MB-DF1 – Modbus TCP a DF1 User’s Manual Exemys B. Modbus statistics You can monitor the internal statistics by reading Modbus locations. These data are the same that those provided through the web service. Think of this method as a way to gather statistics by means of a SCADA that eventually could store a log just by issuing periodical Modbus TCP reads. -

EGW1-IA3-MB-DF1 – Modbus TCP a DF1 User’s Manual Exemys E. Configuring FlexLogix and ControlLogix PLCs Time ago, Allen Bradley came out with some modifications about the way that newer PLCs exchange data. In the new approach, the PLC defines tags to map data, rather than Files. At the moment of this publication, those PLCs belong to the FlexLogix and ControlLogix family. -
