ENGLISH 4 Software Implementation of the Gateway 4 2 8 Description of Services Assigned to Gateway O On the FIPIO network all the inputs outputs that correspond to the gateway are periodic the same is not true of the Modbus network There are therefore two types of service periodic services and aperiodic services All of these services correspond to FIPIO objects For a more detailed description see Chapter 5 FIPIO Objects Available for Programming page 38 Periodic communications inputs For the configuration described here the value of each of the first 8 gateway input words corresponds to the value of the status register of a TeSys U motor starter register located at address 455 Periodic communications outputs Likewise the value of each of the first 8 gateway output words corresponds to a value to be sent to the command register of a TeSys U motor starter register located at address 704 The FIPIO objects corresponding to the gateway s periodic Modbus communications are described in Section 5 1 Periodic Command and Control Words page 39 See also Section 11 3 Command and Control of the 8 TeSys U Motor Starters page 115 for an example of how these periodic communications services are used with the type of configuration adopted in this gateway implementation 8 TeSys Us If you delete any motor starters from the configuration you will need to adjust the two tables on the previous page according

202. us responses and output memory for the contents of the queries 11 1 Introduction The periodic exchanges between the FIPIO master PLC and the LUFP1 gateway are limited to transferring the contents of the gateway s input memory to the IW inputs on the PLC and transferring the PLC s QW outputs to the gateway s output memory gt Each LUFP1 gateway is delivered so that it can be configured using PL7 PRO instead of ABC LUFP Configurator This method makes the gateway easier to configure However the gateway is limited to a blank pre configuration as it will be configured by the master PLC itself when the FIPIO network is initialised The FIPIO network is totally separate from the Modbus network The frames on a network are not directly translated by the gateway to generate frames on the other network Instead the exchanges between the contents of the gateway s memory and the Modbus slaves make up a system independent of the one entrusted with managing the exchanges between the gateway memory and the FIPIO master The following synopsis illustrates the independent management of each of the two networks Management of FIPIO master gateway Modbus slave exchanges LUFP1 Gateway PL7 PRO Configuration of FIPIO exchanges for the Input memory master PLC by user excluding programming 0x0000 gt 0x0033 p W AU Profile standard profile FED C32 P LAS Service a PKW Response and LUFP1
